com NEC's φ50 µm InGaAs APD IN COAXIAL PACKAGE NR8501 Series FOR 2.
5Gb/s APPLICATIONS FEATURES • SMALL DARK CURRENT: ID = 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 = 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 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.
