1310nm InGaAsP strained MQW DFB LD for 1.25G Ø2.0 TO CAN
Description
KLT231412x
is long wavelength distributed feedback(DFB) laser diode(LD) sources in TO-56 package with
Ø2mm ball lens cap.
KLT231412x
consists of an InGaAsP strained multi-quantum well(MQW) LD and an InGaAs PIN-PD for output
monitoring.
It operates at 1310nm wavelength band and with data rates of 1.25 Gbps.
It is suitable for fabricating pigtailed LD source, TOSA(transmitter optical sub assembly), and bi-directional module.
FEATURES
High performance strained MQW InGaAsP LD with BH(buried hetero-junction) structure
Hermetically sealed TO-56 package with 2mm ball lens cap
High reliability and environmental endurance
Operating wavelength of 1.3µm band
Operating temperature range from 0°C to 70°C
Data rates of 1.25Gbps
APPLICATIONS
SONET OC-24/SDH STM-8
1.25Gbps Gigabit Ethernet
Suitable for fabrication of coaxial LD module, TOSA, and Bi-Di module
