Mini Single Window Single Mode Fiber Coupler

The Oplink mini fused single window wideband fiber 1x2 (2x2) couplers provide

accurate optical signal coupling and splitting over wide bandwidth with high

performance and high reliability in miniature or sub-miniature package. These

couplers have excellent uniformity, low excess loss and very low polarization

sensitivity and are available with various tap ratios, wavelength ranges, fiber

types, and connector options. The small form factor with reduced cladding fiber

is essential for compact system integration. All devices are shown to be able to

handle high optical power up to 4W and are tested according to industry stan-

dard procedures. Reliability is guaranteed through stringent tests to fully meet

Telcordia GR-1221 requirements.

Oplink can provide customized designs to meet specialized feature applications. Also,

Oplink offers modular assemblies that integrate other components to form a full

functionmodule or subsystem.
