.. NEC's φ50 µm In Ga As APD IN COAXIAL PACKAGE NR8501 Series FOR 2.5Gb/s APPLICATIONS Features - SMALL DARK CURRENT: ID = 7 n A - 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: f C = 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) DESCRIPTION NEC's NR8501 Series are In Ga As avalanche photo diode (APD) coaxial modules with optical fiber pigtail. They are designed for long wavelength 2.5 Gb/s optical munication systems and are ideal as a reciever for Synchronous Digital Hierarchy (SDH) system, STM-16 ITU-T remendations.
