PULSED LASER DIODE

IN COAXIAL PACKAGE

FOR OTDR APPLICATION (20 mW MIN)

NX7529BB-AA

FEATURES

• HIGH OUTPUT POWER:

Pulse Conditions: Pulse width (PW) = 10 µs, Duty = 1%.

• LONG WAVELENGTH:

NEC's NX7529BB-AA is a 1550 nm Multiple Quantum Well

(MQW) structured Fabry-Perot (FP) laser diode coaxial mod-

ule with single mode fiber. This module is specified to operate

under pulsed conditions and is designed for a light source of

Optical Time Domain Reflectometer(OTDR).
