NX7302CA-CC Datasheet | CEL

FEATURES - CENTER WAVELENGTH: λC = 1310 nm - OPTICAL OUTPUT POWER: Pf = 0.2 m W - LOW THRESHOLD CURRENT: ITH = 9 m A - HIGH CUTOFF FREQUENCY: f C = 2.0 GHz - In Ga As MONITOR PIN-PD - WITH SC-UPC CONNECTOR - WIDE OPERATING TEMPERATURE RANGE: -40 to +85°C - BASED ON TELCORDIA RELIABILITY DESCRIPTION NEC's NX7302BA-CC and NX7302CA-CC are 1310 nm Fabry Perot (FP) laser diode coaxial modules with single mode fiber. They have a Multiple Quantum Well (MQW) structure and a built-in In Ga As monitor photo diode. These modules are ideal as light sources for Synchronous Digital Hierarchy (SDH) systems, STM-4 and short-haul S-4.1 ITU-T remendations.
