NEC's φ50 µm

InGaAs APD IN COAXIAL PACKAGE

NR8500 Series

FOR 155 Mb/s AND 622 Mb/s APPLICATIONS

FEATURES

DESCRIPTION

NEC's NR8500 series is an InGaAs avalanche photo diode

(APD) coaxial module with optical fiber pigtail. This module is

designed for long wavelength optical communication systems

and is ideal as a reciever for Synchronous Digital Hierarchy

(SDH) system, STM-4 and STM-1, ITU-T recommendations.

• SMALL DARK CURRENT:

I^D= 7 nA

• HIGH SENSITIVITY:

S = 0.94 A/W at λ = 1310 nm, M = 1

S = 0.96 A/W at λ = 1550 nm, M = 1

• HIGH SPEED RESPONSE:

fC = 1.5 GHz at M = 10

• COAXIAL MODULE WITH SMF or GI-50 FIBER

• WITH SC CONNECTOR: Standard

FC CONNECTOR: Option

ELECTRO-OPTICAL CHARACTERISTICS (TC = 25°C, Unless otherwise specified)
