| Ultra-Low PDL Fused Tap Coupler (1310, S, C, L band) LPTC Series Features Wavelength Independent Low Insertion Loss and PDL High Power Handling Guaranteed Reliability Ultra-Low PDL Fused Tap Coupler (1310, S, C, L band) The Oplink LPTC (1x2 and 2x2) coupler series feature exceptionally low polarizatio dependent loss on both signal and tap ports as well as excellent uniformity and low excess loss. They 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. Reliabilityisguaranteed 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.

Values are referenced without connector loss. 2. Change in insertion loss from -5 to 75C. Values are depended on coupling ratio, for 99/1 coupler Temperature Dependent Loss (TDL) ~0.02/0.20dB. As tap ratio increase, TDL decreases for tap path, while increases for signal path. All TDL is specified from -5 to 75C 3. Operating temperature range changes to -5 to 75C in P2, P3 package and all package with connectors. 4. The mechanical tolerance should be +/-0.2 mm on all package dimensions unless otherwise custom specified. Oplink Communications, Inc.
