NEC's 1310 nm InGaAsP MQW FP LASER DIODE NX7303BA-CC IN COAXIAL PACKAGE NX7303CA-CC FOR 155 Mb/s APPLICATION FEATURES DESCRIPTION • CENTER WAVELENGTH: λC = 1310 nm • OPTICAL OUTPUT POWER: Pf = 1.0 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 NEC's NX7303BA-CC and NX7303CA-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 a light source for Synchronous Digital Hierarchy (SDH) systems, STM-1 and long-haul L-1.1 ITU-T recommendations.
