With the nation’s most extensive Fibre providers, including AT&T, Verizon, Frontier, Lumen (CenturyLink / Quantum), and Windstream planning to pass 55 million homes on Fibre by 2030, Fibre installations mean that connecting Internet services is becoming more and more critical and needs to be understood.
Overall, Fibre optic installation bridges the gap between households that “can” be connected to Fibre and homes that “can” be connected to Fibre – to provide high-speed Internet, video, and voice. High. In other words, the customer penetration rate of a Fibre supplier.
Digital Infra provides a detailed overview of the Fibre optic installation process, including Fibre removal, Fibre splicing, “concealment” or terminal box installation, Fibre entry into the home, end-to-end setup optical network (ONT), and enables Internet, video, and voice services over Fibre.
What is Fibre installation?
Fibre installation is a home’s transition from the “home connection” phase of construction to the “connection” or installation phase with Fibre optics. The differences between these two phases are:
Household pass: The Fibre optic cable is “passed through the house along the street,” meaning that the house is “possible” to be serviced by the provider’s Fibre optic distribution facility but may not yet be “connected.” do
Connected: A Fibre optic “drop” cable connects to your home from the nearest network access point. It allows customers to order and receive Internet, video, and voice services from Fibre providers.
Preparing for Fibre Optic Installation
Before laying Fibre for home use (FTTH), Fibre providers perform civil engineering, preparation, and permitting work, including the following tasks:
Civil Engineering:
- Site survey
- Site inspection
- utility competition analysis (e.g., power and water)
- Mapping
Preparation:
Field survey of the ground or utility poles used to bring Fibre from roads to homes.
To take proper permission:
- Submission of engineering plans.
- details of equipment installation or relocation.
- We are securing municipal use rights.
What is meant by Fibre Drop?
A Fibre optic drop is a process by which a Fibre optic service provider’s access point is connected via a Fibre optic cable to an optical network terminal (ONT) at the customer’s home.
A Fibre optic “drop” cable must be installed and connected from the “home connection” point to the home to activate the new service.
This location is called a “drop point” and may take the form of a Fibre optic pedestal (above a ground access point), handhole, maintenance hole, chamber, or utility/telephone pole.
“Originating Point” means the location where a Fibre Transport Network Feeder Cable originating from the Fibre Provider’s Central Office (CO) terminates or terminates. Another standard method of joining Fibres when they are unterminated or unterminated is called splicing.
From the “starting point,” the Fibre optic installer connects the Fibre optic drop cable to the box on the outside wall of the house in two ways:
- Underground: Install Fibre optic cables underground using tillage, ditching, or directional drilling techniques. Fibre optic cables can be routed to homes through this infrastructure if underground ducts are installed.
- Aerially: Fibre optic cables are routed to the customer’s home via overhead power lines or utility poles.
Fibre splicing
“Fibre splicing is the Fibre-to-Fibre connection it Joins the ends of the two Fibre strands.” The following describes the preparation and process of Fibre splicing.
Preparing for Fibre optic cable connections
Preparing the Fibre for splicing involves stripping the Fibre optic cable down to the Fibre itself and removing all protective components:
- In this installation example, the Fibre optic cable includes a metal shield within the outer jacket, multiple Fibre strands within the buffer tube, Kevlar strands to protect the buffer tube further, and a ripcord used to remove the outer coat. Increase.
- Preparation begins by removing part of the outer jacket of the Fibre optic cable using a ripcord. It exposes the metal shield, buffer tube, and Kevlar strands. Then remove and discard the metal shield and Kevlar strands, leaving only the bare core casing. Pulling back the buffer tube exposes the optical Fibre used for splicing.
- After the Fibre is stripped, it is cleaned with alcohol, placed in a holder, and cut to precise lengths with a Fibre cutter. A splice protection sleeve is added to protect the Fibres after splicing.
How to splice Fibre optic cable? Splicing is commonly used to connect “active” Fibres brought into the home to newly installed Fibres within the home. Below are two examples of splicing Fibre optics at different locations in your home. - Fibre drop connection: The video below shows how to splice a Fibre optic drop at a Fibre optic socket “drop” point outside a customer’s home. This splicing allows a single Fibre to be routed and installed at the customer’s home.
- Fibre connection at Optical Network Terminal (ONT): The video below shows the Fibre splicing at the optical network terminal (ONT) mounted on the wall of the customer’s home.
Methods for Fibre splicing
There are two methods of Fibre splicing:
- Fusion splicing
- Mechanical splicing.
Fusion splicing is the most commonly used method for splicing optical Fibres. The fusion splicing process uses a unique fusion splicer to precisely align the two Fibre ends. Then “weld” the edges of the glass with an arc. Then use the heater on the fusion splicer to shrink the splice sleeve.
CCTV and Fibre Optics
Most people installed Fibre optics cables to connect the surveillance cameras. Many of us question the method and process of connecting and installing surveillance cameras and connecting Fibre optics with CCTV. The security and surveillance sector has been around for centuries.
But before technology, closed-door televisions, etc., places were most often manually guarded using a few simple weapons. Security guards still exist and have their significance, but there is great value in installing a CCTV video system kit.
Whether in an industrial unit, campus, or gated community, having the right surveillance system in place is extremely important given today’s conditions and applicable worldwide. Surveillance systems have become more complex today and can be connected to network networks using Ethernet cables.
As Fibre becomes more critical, legacy networks will be replaced or combined with this new evolving technology. In a Fibre optic or mixed network, you can choose Fibre optic cable for CCTV connection to your network. This post guides using Fibre optic cable for CCTV applications and more.
Advantages of Fibre Optics Cables
- Fibre optic cables offer the highest bandwidth performance of any media type used in security and surveillance camera systems today. A recent trend in surveillance cameras is the move to Internet Protocol (IP), taking advantage of the low-cost Ethernet system electronics, digital transmission, and ability to work with multiple security systems.
- Multimode Fibre is the predominant Fibre type for analog and digital Ethernet systems up to 2 kilometers (km). In contrast, single-mode Fibre is the choice for distances greater than 2 km in digital Ethernet systems. Optical Fibre is a dielectric transmission medium immune to electromagnetic interference (EMI) and radio frequency interference (RFI).
- There are no isolation restrictions for indoor or outdoor placement from sources of EMI or RFI intrusion, such as motors, fluorescent lights, or power cords. Near-end and far-end crosstalk issues associated with unshielded twisted-pair copper (UTP) communication cables do not apply to Fibre optic cables.
- UTP and coaxial cables on copper are prone to ground loops and require surge protection in addition to environmental EMI. Due to its dielectric nature, there is no EMI output signal to pick up, making Fibre optic the safest and most reliable transmission method possible.
- Physically tapping the Fibre requires considerable skill to do so undetected. After installation, testing and validating Fibre optic cable connections is nothing more than a simple loss measurement for power connections. While TIA/EIA-568B.1 states that field testing/certification of Category 5e or better cabling must comply with several separate electrical tests, optical cables have a single test link loss. Just fill it up.
- Fibre optic cables have the most robust mechanical and environmental performance of any media type used in such security video surveillance systems. Fibre optic cables withstand harsh indoor/outdoor facility installations and harsh environmental conditions without sacrificing reliable video transmission performance.
- Fibre optic cables are smaller than other media types, maximizing path and space utilization. Perfect for indoor and outdoor routing of surveillance or surveillance cameras.
Ways to Connect Security IP Cameras with Fibre Optical Cable
Following are the four ways to connect the security IP cameras with Fibre optical cable:
Use a pair of media convertersMedia converters convert electrical signals to Fibre optic signals and vice versa, allowing camera video to be transferred over Fibre optic cables. Setting up a Fibre optic connection requires two media converters on each side.
There are usually two terminal ports with converters – RJ45 and SFP Fibre. As well as a convenient Ethernet port, the RJ45 connects to surveillance cameras or the leading network. The two Fibre optic ports are connected via a Fibre optic cable. The Fibre optic cable distance between the camera and the leading network is 80 km.
The choice of Fibre optic cable and connector depends on the SFP modules installed in the media converter. SFP module is a critical component of a media converter that generates light. Single-mode Fibre optic cable is better suited for surveillance cameras because the total distance is longer than multimode Fibre.
SC and LC are Two Types of Connectors
- SC connectors are about two sizes larger than LC connectors. SC connectors are ideal for manual Fibre optic connections.
- LC connectors must be machined with tools. Performance has to be treated differently when it comes to media converter solutions.
Both the camera and media converter require power. It contrasts with copper connections, where you can use PoE technology to transmit power and data over a simple Ethernet cable. Fibre optic technology transmits light, which cannot be carried by electricity.
Fibre Optics with Copper Wire
A second option is to replace the front media converter with a Fibre optic PoE extender. You can think of it as a particular type of media converter. Besides converting the video stream to a Fibre optic signal, the extender also provides PoE for remote IP cameras.
The media converter accepts a power input range of 12VDC to 48VDC, so the conversation can move the power supply to the rear if AC power is unavailable on the front end. In this case, two copper wires or a composite Fibre can be used to supply direct current. B. Transmitting 48 V DC.
The maximum distance between the power adapter and the camera is 2.5 km. Also, the outdoor environment can be harsh, especially in the summer when the sun is cooking the case. Therefore, all media converters, SFP modules, and extenders must withstand a wide temperature range. Industrially cured products are used for this outdoor application.
Fibre PoE Switch and Media Converter
A Fibre optic PoE switch is helpful if you have multiple security IP cameras in an area. A Fibre optic PoE switch has multiple ports that can accommodate multiple IP security cameras, providing data and power over a single Ethernet cable.
Instead of running each Fibre optic cable to each security IP camera, one Fibre optic connection between the media converter and the Fibre optic PoE switch is sufficient. A convenient Ethernet cable maintains the connection between the Fibre optic PoE switch and the camera. Thanks to PoE technology, there is no longer a need for power and the need to close each camera.
Simplify network design and save overall costs. However, this solution is controversial. Some people prefer separate Fibre connections between each IP camera because the leading network is more reliable. One of the Fibre optic connections is not working, but it does not affect the rest of the cameras.
As long as the Fibre optic PoE switch and its components, including the power supply and SFP module, are industry-hardened products, the Fibre optic PoE switch is still a reliable solution.
Optical Fibre PoE Ring Network
Take pictures from all the cameras placed on the road or cycle over a large area. Topology network infrastructure is inconvenient and complex. Ring Fibre networks are interconnected using Fibre optic cables to create a daisy chain. You might think that if one of the switches fails, all the cameras connected to that switch go offline.
A ring network must address these issues. To establish connectivity, the first switch must connect to the last switch. Create redundant paths. If one of the switches fails, the network will reverse and follow the opposite path back to the leading network.
Because the Fibre is compact and a thin wire can carry multi-strand glass Fibre, it is easy to set up straight Fibre connections with returned strand wires in the same conductor. A Fibre optic ring network requires a dedicated Fibre optic PoE switch.
Just connecting two switches with two Fibre optic patches breaks the IEEE802.3 protocol. Switches have firmware that determines which path to send data directly.
