TYPE
NAME ML720J45S , ML720K45S, ML720Y45S
ML725B45F , ML725C45F
DESCRIPTION
ML7XX45 series are InGaAsP laser diodes which provide
a stable, single transverse mode oscillation with emission
wavelength of 1310nm and standard continuous light output
of 5mW.
ML7XX45 are hermetically sealed devices having the photo
diode for optical output monitoring. This is suitable for such
applications as FTTH (Fiber to the Home) and ~ 1Gbps Ethernet
/ Fiber channel systems.
FEATURES
•1310nm typical emission wavelength, FP-LDs
•Low threshold current, low operating current
•Wide temperature range operation
(Tc=-40 to 85deg.C)
•φ5.6mm TO-CA N package
Flat window cap : ML720J45S, ML725B45F
Ball lens cap : ML720K45S, ML725C45F, ML720Y45S
APPLICATION
•~155Mbps FTTH system
•~1Gbps Ethernet , Fiber channel
