LASER DIODE IN COAXIAL PACKAGE
NX7301CA-CC
FOR 155 Mb/s AND 622 Mb/s APPLICATIONS
FEATURES
DESCRIPTION
• CENTER WAVELENGTH:
λC = 1310 nm
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.
• 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 +85°C
• InGaAs MONITOR PIN-PD
• WITH SC-UPC CONNECTOR
• BASED ON TELCORDIA RELIABILITY
ELECTRO-OPTICAL CHARACTERISTICS (TC = -40 to +85°C, unless otherwise specified)
