NX8503BG-CC

NEC's 1550 nm InGaAsP MQW DFB LASER DIODE NX8503BG-CC IN COAXIAL PACKAGE NX8503CG-CC FOR 155 Mb/s AND 622 Mb/s APPLICATIONS FEATURES PEAK EMISSION WAVELENGTH: λP = 1550 nm OPTICAL OUTPUT POWER: Pf = 2.0 mW LOW THRESHOLD CURRENT: ITH = 15 mA @ TC = 25°C InGaAs MONITOR PIN-PD WIDE OPERATING TEMPERATURE RANGE: TC = -10 to +85°C WITH SC-UPC CONNECTOR BASED ON TELCORDIA RELIABILITY DESCRIPTION NEC's NX8503BG-CC and NX8503CG-CC are 1550 nm Coaxial Module DFB (Distributed Feed-Back) laser diode with single mode fiber. Multiple Quantum Well (MQW) structure is adopted to achieve stable dynamic single longitudinal mode operation over a wide temperature range of -10 to +85°C. The module is ideal as a light source for Synchronous Digital Hierarchy (SDH) system, STM-1, log-haul L-1.2, L-1.3 and STM-4, long-haul L-4.2, L-4.3 ITU-T recommendations.
