KLT231544

1310nm InGaAsP strained MQW DFB-LD KLT231544x, 2.5G DFB LD TO CAN Description KLT-231544x is long wavelength distributed feedback(DFB) laser diode(LD) sources in TO-56 package with flat window or ball lens or aspherical lens cap. KLT-231544x 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 2.5 Gbps. It is suitable for fabricating pigtailed LD source, TOSA(transmitter optical sub assembly), and bi-directional module.
