Fully compatible with Fibercore SM800(4.2/80) and SM1500(6.4/80)
|
|
|
For fiber optic gyroscope, hydrophone and telecom applications
|
|
|
1x2, 2x2, 1x3 and 3x3 configurations
|
A long-established standard in the demanding fiber optic gyroscope (FOG) industry, 80 µm fibers can demonstrate clear superiority over their more conventional 125 µm counterparts in a wide variety of applications in both telecommunications and sensing.
|
Lower intrinsic bending stress reduces susceptibility to static fatigue and enchances lifetime in coiled applications (see Section 1, HB-G). Smaller physical volume saves space – an increasingly scarce commodity within the instrument racks of today’s multi-channel, DWDM systems.
|
Despite these strengths, the lack of compatibile ancillary products has limited general acceptance of 80 µm fibers. Now, high performance, fused-taper couplers are available, fabricated from SM800(4.2/80) and SM1500(6.4/80) – so, if your application really needs 80 µm, you can specify it, with increased confidence.

Ordering Information: Feasa 80 µm Fused-Taper Coupler
To order Couplers, please use part numbers in this format:
FSC –
(1) – (2) – (3) – (4)
Where:
(1) Fiber Type – SM800(4.2/80) or SM1500(6.4/80)
(2) Splitting-Ratio – 1 – 99% (1x2 and 2x2 only)
(3) Port Configuration – 1x2, 2x2, 1x3, 3x3
(4) Package Type – S (Standard), M (Miniature), UM (Ultra Miniature)
For example ‘SM800(4.2/80) – 50 – 1x2 – M’ would be
an 830 nm Coupler, fabricated in Fibercore SM800(4.2/80) with the input split
50:50 between two output ports, in a 45 mm x 3 mm package.
