Ultra-Low PDL Fused Tap Coupler (1310, S, C, L Band) LPTC Series Product Description The Oplink LPTC (1x2 and 2x2) coupler series feature exceptionally low polarization 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 function module or subsystem.

Temperature Dependent Loss (TDL) is defined as Insertion Loss ( IL) variation within –5 to 75 °C operating temperature. For example, TDL are 0.2dB and 0.02dB respectively for the two ports of 1/99% tap coupler. Smaller coupling ratio tends to have higher TDL. A 5% tap coupler has smaller TDL than 1% tap coupler on tap port and higher TDL on signal port. [3] Operating temperature range at -5 to 75°C 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. [1] [2] S0093 - R04.
