Learn fiber optic splicing: What is Fiber Optic Splicing?

It is a process used by a professional to fuse two or more fiber cables. Fiber optic splicing typically results in lower light loss and back reflection than termination making it the preferred method when the cable runs are too long for a single length of fiber or when joining two different types of cable together, such as a 48-fiber cable to four 12-fiber cables. Let us learn fiber optic splicing points.

Fiber Optic Splicing Work Steps

Step #1 – Strip the fibers  The splicing process begins with the preparation for both fibers ends to be fused. So you need to strip all protective coating, jackets, tubes, strength members and so on, just leaving the bare fiber showing. It is noted that the cables should be extremely clean.

Step #2 – Clean and cleave the fibers    A good cleaver is necessary for a successful splicing.

Step #3 – Fuse the fibers   

Step #4 – Protect the fiber  Use heat shrink sleeves to protect the optical fiber.

Learn fiber optic splicing: not Splice When Optic In Fiber

It cannot be spliced when there is light in the optical fiber, because splicing when there is light may cause deterioration of splicing quality. The splicing fiber has high loss, or even broken.
bad fiber splicing
Especially do not splice the optical fiber if it is connected to a high-power device, such as catv amplifier and CATV fiber optic transmitter. These device produce much strong optical, which may cause damage to the fiber splicer machine or other testing device, like OTDR etc.
Another reminder,
Do not look directly at the end face of the fiber when cleaving the fiber or it may be blinding. Most laser light sent down an optical fiber is at a level that will permanently damage an eye for sure and fast to.

Lomoveishiy – Finland

I needed those to connect my PC on the third floor to have internet access in that room, and ISP installed their modem on the first floor only. After dropping fiber patch cables, plugged in all cables into these media converters at both sides, and link came up instantly. Was much easier than I thought!

Raymond – USA

Great experience – units worked straight out of the box – just needed plug in cables and we were done. I also like the possibility to enable jumbo frames, while we do not have a need for this feature at the current moment it’s great to have this option.
