Passive Interconnect Components
Fiber Optic splitters/couplers
Fused(FBT) Couplers
Coupler is kind of passive components, its main function is to redistribute the input light wave as required, avoid
interrupting modulating signals.
In the application of communication, some important technique parameters are must be considered, including center
wavelength, bandwidth, typical excess loss, coupling ratio and the necessary environmental stability.
FOCONEC all-optical fused couplers which employ FBT technique are proven to have high performance in applications,
and eliminate reverse-directional reflection. Our Couplers ensure above-60dB directivity, and long-time good stability.
We offer 1x2 or 2x2 fused couplers with steel tube or plastic cassette package, The diameter of input/output cables will
be 0.9mm, 2.0mm or 3.0mm. SC, LC, FC, ST connectors could be pre-terminated at both input and output ends, and PC,
UPC or APC polishing are available.

Cassette Type Tree/Star Fused Coupler are offered with standard
1x4, 1x8, 1x16 or custom specified port configurations, offering low
insertion loss, low polarization dependence, well controlled uniformity
as well as excellent environmental stability. Standard tree/star coupler
have been widely used to split and mix optical signals in CATV, LANs
and all other kinds of optical communication systems.
The diameter of input/output cables could be 0.9mm, 2.0mm or
3.0mm, and SC, LC, FC, ST connectors with PC, UPC or APC polishing
could be pre-terminated at both input and output ends.
