diodes for 2.5Gbps transmission emitting light beam at 1310nm.
ML7XX34 can operate in the wide temperature range from -40^oC to
95 ^oC without any temperature control.
APPLICATION
2.5Gbps transmission
FEATURES
· Wide temperature range operation (-40^oC to 95^oC)
· High side-mode-suppression-ratio (typical 40dB)
· High resonance frequency (typical 11GHz)
