DATA SHEET
PHOTO DIODE
NR7800 Series
φ80 µm InGaAs PIN-PD COAXIAL MODULE
FOR 622 Mb/s, 156 Mb/s FIBEROPTIC COMMUNICATIONS
AND EDFA MONITOR
DESCRIPTION
The NR7800 Series is an InGaAs PIN photo diode (PIN-PD) coaxial module with optical fiber pigtail. This module
is designed for long wavelength optical communication systems and ideal as a receiver for Synchronous Digital
Hierarchy (SDH) system, STM-4 and STM-1, ITU-T recommendations.

S = 0.89 A/W @ λ = 1 310 nm
S = 0.94 A/W @ λ = 1 550 nm
• Low operating voltage
VR = 5 V
• Coaxial module with SMF or GI-50 fiber
• With SC connector : standard, FC connector : option
