OPLINK DWFC0240P00HP

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.
