Description This BOSA is a high performance optical sub-assembly in single fiber by using 1310nm transmitter and 1490nm receiver. The transmitter section uses a multiple quantum well 1310nm DFB laser supporting burst-mode operation. The receiver section uses a TO-can built in a long wavelength PIN diode and a 2.5Gbps Super transimpedance amplifier. Applications ● GPON BOB ONU optical modem, class B+ ● GPON ONU transceiver ● FTTH Bi-directional play
