| NEC's 1310 nm InGaAsP MQW FP LASER DIODE NX7303BA-CC IN COAXIAL PACKAGE NX7303CA-CC FOR 155 Mb/s APPLICATION FEATURES * CENTER WAVELENGTH: C = 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 +85C * BASED ON TELCORDIA RELIABILITY DESCRIPTION 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.
