NX8564/8565/8566LE Series
EA MODULATOR INTEGRATED
1 550 nm MQW-DFB LASER DIODE MODULE FOR
2.5 Gb/s DWDM ULTRALONG-REACH 360 km, 600 km, 240 km APPLICATIONS
DESCRIPTION
The NX8564/8565/8566LE Series is an Electro-Absorption (EA) modulator
integrated, 1 550 nm Multiple Quantum Well (MQW) structured Distributed
Feed-Back (DFB) laser diode. The module is capable of 2.5 Gb/s applications
of over 360 km, 600 km, 240 km ultralong-reach and available for Dense
Wavelength Division Multiplexing (DWDM) wavelengths based on ITU-T
recommendations, enabling a wide range of applications.
FEATURES
