Dual Window Single Mode Wideband

Fiber Coupler (1310 nm and 1510 nm band)

DWFC Series

Product Description

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

accurate optical signal coupling and splitting over wide bandwidth with high

performance and high reliability.These couplers have excellent uniformity, low

excess loss and very low polarization sensitivity and are available with various

tap ratios, fiber types, and connector options. All devices are shown to be able

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

standard procedures. Reliability is guaranteed through stringent tests to fully

meet Telcordia GR-1221 requirements.
