NX8511UD
1 550 nm FOR LONG HAUL 2.5 Gb/s
InGaAsP MQW-DFB LASER DIODE TOSA
DESCRIPTION
The NX8511UD is a 1 550 nm Multiple Quantum Well (MQW) structured
Distributed Feed-Back (DFB) laser diode TOSA (transmitter optical sub-
assembly) with InGaAs monitor PIN-PD in a receptacle type package
designed for SFF/SFP transceiver with LC duplex receptacle.
This device is ideal for Synchronous Digital Hierarchy (SDH) system, long
haul STM-16 (L-16.2), ITU-T recommendations, and SONET OC-48 (LR-2).
FEATURES
• Peak emission wavelength
• Optical output power
• Wide operating temperature range
• Side mode suppression ratio
• InGaAs monitor PIN-PD
• Internal optical isolator
• Based on Telcordia reliability
