SUB-MINIATURE TAP COUPLER
Fused Fiber Coupler
The sub-miniature tap coupler provides low loss splitting and monitoring in an ultra-short 32 mm length package.
Designed for space constrained applications, the product is manufactured using Ø 80 µm cladding fiber. This enables low fiber bend radius within modules, without compromising mechanical integrity.
Standard wavelengths of operation are the C, L, C+L or S bands for fiber amplifier applications. Many other wavelengths are available for requirements such as sensing, fiber lasers and fiber Gyros. Do not hesitate to contact us with your specific requirements.
Reliability is assured through qualification to Telcordia GR-1221.
