XGPON ONU BOSA N1 SC APC UPC pigtail Receptacle TX 1270nm DFB 2.488G 2.5G 2G RX 1577nm APD 9.953G 10G FTTH FTTX
Description
This XGPON BOSA is a high performance optical sub-assembly in single fiber by using 1270nm transmitter and 1577nm receiver.
The transmitter section uses a multiple quantum well 1270nm DFB laser supporting burst-mode operation. The receiver section uses a TO-can built in a long wavelength APD chip and a 10Gbps trans-impedance amplifier. High optical isolation and reflection free is achieved by using CWDM filter and optical isolator.
