GEPON ONU BOSA PX20 SC UPC APC Pigtail TX 1310nm FP RX 1490nm PIN 1.25G 1G FTTH FTTX
GEPON ONU BOSA PX20 SC UPC APC pigtail Receptacle TX 1310nm FP RX 1490nm PIN 1.25G 1G FTTH FTTX
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.
