1X2 ST/PC Multi-mode FBT Coupler

Description:

FBT optical fiber splitter is a type of optical power management device that is fabricated using Fused Biconical Tape technology.

It features small size, high reliability, cheap cost and good channel-to-channel uniformity, and is widely used in PON networks to realize optical signal power splitting.
