The XGS-PON ONU stick transceiver is an Optical Network Terminal (ONT) with Small Form-factor Pluggable (SFP+) packaging. The XGS-PON ONU stick integrates a bi-directional (max 10Gbit/s) optical transceiver function and 2nd layer function. By being plugged into the customer premise equipment (CPE) with standard SFP port directly, the XGS-PON ONU stick provides multi-protocol link to the CPE without requiring separate power Supply.
The transmitter designed for single mode fiber and operates at wavelength of 1270nm. The transmitter uses a DFB laser diode and fully compliant with IEC-60825 and CDRH class 1 eye safety. It contains APC functions, a temperature compensation circuit to ensure compliance with ITU-T G.9807 requirements at operating temperature.
The receiver section uses a hermetic packaged APD-TIA (APD with trans-impedance amplifier) and a limiting amplifier. The APD converts optical power into electrical current and the current is transformed to voltage by the trans-impedance amplifier. The differential signals are produced by the limiting amplifier. The APD-TIA is AC coupled to the limiting amplifier through a low pass filter.
The XGS-PON ONU stick supports a sophisticated ONT management system, including alarms, provisioning, DHCP and IGMP functions for a stand-alone IPTV solution at the ONT. It can be managed from the OLT using G.988 OMCI.
