FiberCom has developed compact package, tube size 40mm or shorter for a wide variety of couplers,
including Wideband, Dual Window, Ultra-Low PDL types. It is bi-directional passive device made b
y
the fused biconic taper (FBT) fusing process ensuring consistent quality, reliability and high
p
erformance. These components provide low insertion loss and high directivity at all various
splitting ratios.
