FOR 622 Mb/s APPLICATIONS
FEATURES
DESCRIPTION
• CENTER WAVELENGTH:
λC = 1310 nm
• OPTICAL OUTPUT POWER:
Pf = 0.2 mW
• LOW THRESHOLD CURRENT:
ITH = 9 mA
• HIGH CUTOFF FREQUENCY:
fC = 2.0 GHz
• InGaAs MONITOR PIN-PD
• WITH SC-UPC CONNECTOR
• WIDE OPERATING TEMPERATURE RANGE:
-40 to +85°C
• BASED ON TELCORDIA RELIABILITY
NEC's NX7302BA-CC and NX7302CA-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 light sources for Synchronous Digital Hierarchy (SDH)
systems, STM-4 and short-haul S-4.1 ITU-T recommendations.
