NX7302BA-CC

NEC's 1310 nm InGaAsP MQW FP LASER DIODE NX7302BA-CC IN COAXIAL PACKAGE NX7302CA-CC FOR 622 Mb/s APPLICATIONS FEATURES CENTER WAVELENGTH: λC = 1310 nm OPTICAL OUTPUT POWER: Pf = 0.2 mW LOW THRESHOLD CURRENT: ITH = 9 mA HIGH CUTOFF FREQUENCY: fC = 2.0 GHz InGaAs MONITOR PIN-PD WITH SC-UPC CONNECTOR WIDE OPERATING TEMPERATURE RANGE: -40 to +85°C BASED ON TELCORDIA RELIABILITY DESCRIPTION NEC's NX7302BA-CC and NX7302CA-CC are 1310 nm FabryPerot (FP) laser diode coaxial modules with single mode fiber. They have a Multiple Quantum Well (MQW) structure and a built-in InGaAs monitor photo diode. These modules are ideal as light sources for Synchronous Digital Hierarchy (SDH) systems, STM-4 and short-haul S-4.1 ITU-T recommendations.
