| Polarization Maintaining WDM Couplers |
Gould's truly fused polarization maintaining WDM couplers offer high extinction ratio with polarization launch into a single or dual axis (Slow & Fast) .Gould utilizes our proven Fused Biconical Taper (FBT) process to manufacture polarization maintaining couplers.
Key Strengths
- Low Loss
- Low back-reflection
- Made in U.S.A. on Gould's Proven high reliability Fused Biconical Taper (FBT) Process
