1550nm InGaAsP strained MQW for FP-LD Ø2mm ball lens TO CAN
KLT-155452x
Rev.002
Description
KLT-155452x series are long wavelength Fabry-Perot LD sources in TO-56 package with ball lens cap
KLT-155452x series consist of an InGaAsP strained multi-quantum well(MQW) laser diode(LD) and an InGaAs
PIN-PD for output monitoring. They operate at 1550 nm wavelength band and with various data rates from
155Mbps upto 1.25 Gbps.
They are 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 Ø2.0mm ball lens cap
● High reliability and environmental endurance
● Operating wavelength of 1.55µm band
● Wide operating temperature range from –40℃ to 85℃
● Various data rates from 155Mbps upto 1.25Gbps
APPLICATIONS
● SONET OC-1~ OC-48/SDH STM-1 ~ STM-16
● 155Mbps, 622Mbps, and 1.25Gbps for ATM and Ethernet
● Suitable for fabrication of coaxial LD module, TOSA, and Bi-Di module
