NEC's 1550 nm InGaAsP MQW FP

PULSED LASER DIODE IN DIP PACKAGE

FOR OTDR APPLICATION (135 mW MIN)

NX7561JB-BC

FEATURES

DESCRIPTION

NEC's NX7561JB-BC is a 1550 nm developed strained Mul-

tipleQuantumWell(st-MQW)structurepulsedlaserdiodeDIP

module with single mode fiber and internal thermoelectric

cooler. It is designed for light sources of optical measurement

equipment (OTDR).

• HIGH OUTPUT POWER:

Pf = 135 mW MIN at IFP = 1000 mA,

Pulse width (PW) = 10ms, Duty = 1%

• LONG WAVELENGTH:

λC = 1550 nm

• INTERNAL THERMOELECTRIC COOLER

• HERMETICALLY SEALED 14 PIN DUAL-IN-LINE PACKAGE

• SINGLE MODE FIBER PIGTAIL

ELECTRO-OPTICAL CHARACTERISTICS (TLD = 25°C, TC = -20 to +65°C, unless otherwise specified)
