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.
