For OC48 transmissions Applications
DenseLight’s uncooled DFB laser diodes cover wavelengths from 1490 nm to 1550 nm supporting direct modulation of up to 2.5 Gbps or OC48 data rates.
Application that can be supported are:
· ITU-T G983 PON transmissions
· SONET/SDH transmission
GENERAL FEATURES
· DFB chip based on reliable Al-free InGaAsP MQW ridge and buried heterostructure design
· Uncooled operation over 0 to 70 deg C
· Direct modulation up to OC48 or 2.5 Gbps
· Wavelengths from 1490 - 1550 nm
