General Description

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.

Optical Characteristics

Note 1: Launched into 9/125um Single Mode Fiber.

Note 2: Measured with a PRBS 2^31-1 test pattern @9.9532Gbps and ER=6dB, BER ≤10-3.

Electrical Characteristics

Note 1: Measured with a PRBS 2²³-1 test pattern @2.488Gbit/s and ER=9dB, BER =10^-12.

Note 2: A decrease in optical power above the specified level will cause Los output to switch from a low state to a high state;

An increase in optical power below the specified level will cause Los output to switch from a high state to a low state.

Note 3: CML output, AC coupled internally, guaranteed in the full range of input optical power (-8dBm to -28dBm).

핀 설명

Notes:

1. Default Factory Mode is Tx Fault. For Small Cell type of applications, during Activation/ provisioning, it will be

software configured to ToD.

2. This PIN is an open collector/drain output pin and shall be pulled up with 4.7K-10K ohms to a Host_Vcc on the

host board.

3. PIN7 can support Dying Gasp function. Dying Gasp function is managed by software. If software turn off the dying

gasp function,no influence to the module if logical “0” or “1”. If software turn on the function,no influence to the

module if logical “1”; if logical “0”, the module will report dying gasp to OLT and the module will repeating restart.

4. Default Factory Mode is Veer. For Small Cell type of applications, during Activation/ provisioning, it will be software

configured to 1PPS.
