Appearance of single-mode SC/PC fiber jumper
Select fiber jumpers according to the following rules:
1.
Determine the length of fiber jumpers based on the actual cabling distance.
2.
Determine the fiber type based on the optical module type.
l
Use a multimode fiber jumper for a multimode optical module.
l
Use a single-mode fiber jumper for a single-mode optical module.
3.
Determine the optical connector type based on the interface type.
Ensure that the optical connector at each end of a fiber jumper is the same type as the
interface connected.
Fiber Pigtail
A fiber pigtail is an optical fiber that has an optical connector on one end and a length of exposed
fiber at the other end. The exposed fiber can be fused to another optical fiber. Fiber pigtails are
commonly used to connect optical fibers to optical fiber modules in fiber terminal boxes.
(Couplers and jumpers are also used.)
