10Gbps InGaAsP DFB LASER DIODE
TYPE
NAME
ML792E32/ML792H32
DESCRIPTION
APPLICATION
10Gbps Ethernet/Short Reach
ML7xx32 series are uncooled DFB (Distributed Feedback) laser
diodes for 10Gbps transmission emitting light beam at 1310nm.
l /4 phase shifted grating structure is employed to obtain excellent
SMSR performance under 10Gbps modulation. Furthermore, ML7xx32
