Product ID: 1538
$172.00 – $195.00
780nm 1X2 2X2 Taper Type Optic Coupler with Hi780 Fiber Mini SM Fiber Coupler
780nm 830nm 850nm fused tapered optical fiber coupler (also called tapered splitter, FBT coupler) can couple the optical signals transmitted in the optical fiber at the junction area of the special structure and redistribute the optical power according to the needs. Real-time monitoring, production of unequal splitters, fused tapered splitters are widely used in fiber laser communication systems and OCT systems.
[Features]
Low insertion loss
High isolation
Good interchangeability
High stability and repeatability
