NEC's φ50 µ
µm InGaAs APD
IN COAXIAL PACKAGE NR8501 Series
FOR 2.5Gb/s APPLICATIONS
FEATURES
DESCRIPTION
• SMALL DARK CURRENT:
ID = 7 nA
NEC's NR8501 Series are InGaAs avalanche photo diode
(APD) coaxial modules with optical fiber pigtail. They are
designed for long wavelength 2.5 Gb/s optical communication
systems and are ideal as a reciever for Synchronous Digital
Hierarchy (SDH) system, STM-16 ITU-T recommendations.
• 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 = 2.5 GHz at M = 5
• COAXIAL MODULE WITH SINGLE MODE FIBER (SMF)
or GI-50 Fiber
• WITH SC CONNECTOR: Standard, FC connector: Option
(Refer to Ordering Information)
