SWFC S0070

Single Window Single Mode Wideband
Fiber Coupler (980, 1310, S, C, L, and C+L band)
SWFC Series
Product Description
The Oplink fused single 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, wavelength ranges, 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.

1. Insertion loss over operating wavelength range at ~23°C (excluding PDL and TDL). For S-band product, add 0.1dB due to water absorption peak of fiber.
2. Insertion loss change over the specified wavelength range. For S-band product, add 0.1dB in WDL due to water absorption peak of fiber.
3. Insertion loss change over the all input polarization states.
