Build your own fiber network as a professional Network Engineer

What does a fiber optic network business?

The basic philosophy of modern LAN cabling is the concept of structured cabling. The entire network system is divided into pieces that allow workstation wiring to be concentrated.

In a typical enterprise LAN systems, fiber optic telecommunications network is composed of rooms, backbone cabling, horizontal cabling and workspaces.

Let's illustrate this with a 3-storey building.

For eachplan, there will be a telecommunications room is located on top of each other. These rooms will all telecommunications network equipment like routers, servers and switches. Telecommunication rooms are connected with fiber-optic vertical wells, which are called backbone cabling / electrical cabling or vertical / wiring.

The fiber optic backbone cables usually performed at 10 Gbps Ethernet speeds to provide sufficient bandwidth for the whole company.

The workworkstation areas (PC), divided into compartments. These workstations are connected to each telecommunications room plan with horizontal cables. This horizontal copper / fiber optic cables typically run at 1 Gbps Ethernet speeds.

As the cable pulling the fiber through the vertical axis

The backbone cabling used copper twisted pair. But now the typical single-mode or multimode fiber.

There are many tools availableExtend vertical fiber backbone cables. These include Gopher poles, cable or fish tape drawing tools caster. It usually has an eye for pulling fiber cables and connectors to protect pulling the fiber cables to be installed.

Ending a fiber optic backbone vertical?

The fiber optic backbone to connect without termination (connector). You usually need to solve these connections with fiber optic fibers, asST, SC or LC connectors.

The procedure for termination are not extremely difficult, but it does a thorough training before a good enough job.

Fiber termination tools

The tools needed for fiber terminations are strippers fiber optic cable, Kevlar cutters, fiber cleavers, ST, SC, MTRJ or LC fiber optic connectors, fiber optic connector polishing puck by hand, polishing films and fiber microscope fiber inspection .

Fibreoptical cable termination steps

1. Strip the fiber

Fiber cables come with 3 mm jacket, Kevlar strength member and 0.9 mm coating buffer. To access the fiber coating of 0.125 mm, you have a jacket with a 3 mm fiber jacket stripper, cut, cut the Kevlar fiber with Kevlar, the last buffer strip of 0.9 mm 0.125 mm fiber coated with a stripper.

2. Divide the fiber

After removal of the coating of 0.125 mm fiber, pleaseInsert the fiber into an SC or ST connector LC, and then inject some epoxy in fiber optic connector with a syringe.

You will see the connector and put it in a hot oven until the fiber epoxy cure, so it can keep the fiber taut.

After curing, when it is extra fiber in the connector tip with a fiber cleaver.

3. hand polishing of the fiber

In the next phase connector (fiber glass already installed inside) in one hand polishing puckwhich acts as a fixture, while polishing the front surface of the connector to a high mirror finish to get.

You should keep the puck grinding and polishing of the connector on a connector lapping film in the shape of Figure 8 to 10 ~ 15 times.

Repeat steps to strengthen the hand polishing 12um, 0.5um to 3um lapping film.

4. Termination of fiber quality

The final step is to check the quality of your work. You insert the connector end in a fiber networkinspection microscope that magnifies 200-400 times the level of showing all the scratches and pits that may exist on the front of the connector. If everything seems perfect, you can have the fiber optic networks.
