NEC's 1310 nm InGaAsP MQW FP NX7301BA-CC LASER DIODE IN COAXIAL PACKAGE NX7301CA-CC FOR 155 Mb/s AND 622 Mb/s APPLICATIONS
FEATURES
* CENTER WAVELENGTH: C = 1310 nm * OPTICAL OUTPUT POWER: Pf = 0.2 mW * LOW THRESHOLD CURRENT: ITH = 9 mA * HIGH CUT-OFF FREQUENCY: FC = 2.0 GHz * WIDE OPERATING TEMPERATURE RANGE: -40 to +85C * InGaAs MONITOR PIN-PD * WITH SC-UPC CONNECTOR * BASED ON TELCORDIA RELIABILITY
DESCRIPTION
NEC's NX7301BA-CC and NX7301CA-CC are 1310 nm FabryPerot (FP) laser diode coaxial modules with single mode fiber. They have a Multiple Quantum Well (MQW) structure and a built-in InGaAs monitor photo diode. These modules are ideal as a light source for Synchronous Digital Hierarchy (SDH) systems, STM-4, intraoffice I-4, and STM-1, intraoffice I-1, short-haul S-1.1 ITU-T recommendations.
