| PRELIMINARY DATA SHEET NEC's 1310 nm InGaAsP MQW FP LASER DIODE IN COAXIAL PACKAGE NX7304BG-CC FOR FIBER OPTIC COMMUNICATIONS NX7304CG-CC FEATURES * CENTER WAVELENGTH: C = 1310 nm * HIGH OUTPUT POWER FROM FIBER: PF = 2.0 mW MIN * LOW THRESHOLD CURRENT: ITH = 10 mA * HIGH CUT-OFF FREQUENCY: fC = 2.0 GHz * InGaAs MONITOR PIN-PD * WIDE OPERATING TEMPERATURE RANGE: TC =-40 to +85C * WITH SC-UPC CONNECTOR * BASED ON TELCORDIA RELIABILITY DESCRIPTION NEC's NX7304BG-CC and NX7304CG-CC are 1310 nm Multiple Quantum Well (MQW) structured Fabry-Perot (FP) laser diode coaxial modules with single mode fiber. These modules are ideal as a light source for ITU-T recommended Synchronous Digital Hierarchy (SDH) systems, for fiberoptic communications such as SONET and for digital transmission.
