FPB-X PM Bow Tie Fiber Couplers

Fused; Fiber Type PM Bow Tie; 900-1199 nm; Number of Legs 1x2, 2x2; Splitting Ratio 1/99-50/50; Fiber Length 0.5, 1 m; Excess Loss 0.3 dB; RL 50 dB; Dimensions Ø3.0x60/76, 5x5x85 mm

Gooch & Housego’s FPB-xxxxxxxxx series of fused PM bow tie couplers enable the accurate monitoring and splitting of optical signals in polarization maintaining (PM) fiber. Manufactured using PM bow tie fiber, the FPB-X PM couplers are available in any coupling ratio from 1 to 50%.

Based on Gooch &Housego’s (G&H) fused fiber technology, the FPB-X PM bow tie couplers demonstrate very low loss, high power handling and there is no price penalty for adding a second input port. The center operating wavelength may be chosen from within the 1 μm operating passband, other operating passbands are available dependent on fiber availability.

In common with all PM components, it is necessary to launch into either the slow or the fast axis to maintain polarization. For the G&H PM FPB-X series bow tie couplers, specifications are based on slow axis launch, although fast axis versions are also available if requested.

NOTE: Other component types including ultra-low ratio taps (ULRT) and wavelength division multiplexers (WDM) are available on request, please contact AMS Technologies with your specific requirements.
