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 Co-
axial 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.
