Dual Window Single Mode Wideband Fiber Coupler (1310 nm and 1550 nm band) DWFC Series Features Wavelength Independent Low Insertion Loss and PDL High Power Handling Guaranteed Reliability Applications Dual Window Single Mode Wideband Fiber Coupler (1310 nm and 1550 nm band) 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.
