Fiber Optic Pigtail SC FC LC/APC Coaxial SM 2.5G DFB Laser Diode
Fiber Optic Pigtail Types
Fiber optic pigtails are available in various types: Grouped by
pigtail connector type, there are LC fiber optic pigtails, SC fiber
pigtails and ST fiber pigtails, etc. By fiber type, there are
single-mode fiber optic pigtail and multimode fiber optic pigtail.
And by fiber count, 6 fibers, 12 fibers optic pigtails can be found
in the market.
By Fiber Type
Fiber optic pigtails can be divided into single-mode (colored
yellow) and multimode (colored orange) fiber. Multimode fiber optic
pigtails use 62.5/125 micron or 50/125 micron bulk multimode fiber
cables and terminated them with multimode fiber optic connectors at
one end. 10G multimode fiber cables (OM3 or OM4) are also available
in fiber optic pigtails. The jacket color of 10G OM3 and OM4 fiber
optic pigtail is usually aqua. Single-mode fiber pigtail cables use
9/125 micron single-mode fiber cable and terminated with
single-mode fiber connectors at one end.
By Connector Type
According to different types of pigtail cable connector terminated
at the end, there are LC fiber pigtail, SC fiber pigtail, ST fiber
pigtail, FC fiber pigtail, MT-RJ fiber pigtail, E2000 fiber pigtail
and so on. With different structures and appearance, each of them
has their own advantages in different applications and systems.
Let’s go through some widely used ones.
SC Fiber Optic Pigtail: SC pigtail cable connector is a non-optical
disconnect connector with a 2.5mm pre-radiused zirconia or
stainless alloy ferrule. SC fiber pigtail is economical for use in
applications such as CATV, LAN, WAN, test and measurement.
