| NEC's 1310 nm InGaAsP MQW DFB LASER DIODE NX8303BG-CC IN COAXIAL PACKAGE NX8303CG-CC FOR 622 Mb/s APPLICATION FEATURES * PEAK EMISSION WAVELENGTH: p = 1310 nm * OPTICAL OUTPUT POWER: Pf = 2.0 mW * WIDE OPERATING TEMPERATURE RANGE: Tc = -10 to +85C * SIDE MODE SUPPRESSION RATIO SMSR = 40 dB * InGaAs MONITOR PIN-PD * WITH SC-UPC CONNECTOR * BASED ON TELCORDIA RELIABILITY DESCRIPTION NEC's NX8303BG-CC and NX8303CG-CC are 1310 nm Distributed Feed-Back (DFB) laser diode coaxial modules with an internal optical isolator. These modules are ideal as light sources for Synchronous Digital Hierarchy (SDH) systems, STM-4, long-haul L-4.1 ITU-T recommendations.
