LASER DIODE
NX8509 Series
1 550 nm FOR LONG HAUL 2.5 Gb/s
InGaAsP MQW-DFB LASER DIODE
DESCRIPTION
The NX8509 Series is a 1 550 nm Multiple Quantum Well (MQW)
structured Distributed Feed-Back (DFB) laser diode coaxial module with an
internal optical isolator.
These devices are ideal for Synchronous Digital Hierarchy (SDH) system,
long haul STM-16 (L-16.2), ITU-T recommendations, and SONET OC-48 (LR-
2).
FEATURES
• Internal optical isolator
• Peak emission wavelength
• Optical output power
• Operating case temperature range
• Side mode suppression ratio
• InGaAs monitor PIN-PD
• With SC-UPC connector
• Based on Telcordia reliability
