XGSPON OLT-2XGS-WDM: 2 Port 10G XGSPON OLT with WDM1r

Overview
Overview
The AirLive XGSPON OLT-2XGS-WDM is a recently launched XG(S)-PON OLT with a built-in WDM1r combiner. That caters to new optical fiber communication networks. It conforms to international standards like ITU-T G.9807 (XGS-PON) and ITU-T G.987 (XG-PON) and supports two bandwidth access modes: 1. Asymmetric mode with 2.5Gbps upstream and 10Gbps downstream speed, and 2. Symmetrical mode with 10Gbps upstream and downstream speeds. It also support ITU-T G.984 (GPON). the OLT is compatible with existing GPON OLT and ODN networks, realizing the coexistence of GPON and XG-PON or XGS-PON, making full use of the existing resources, and enhancing the network scalability and cost-effectiveness. It is an ideal fit for high-bandwidth scenarios such as carrier networks, FTTx, and enterprise networks. The compact 1U chassis of the XGSPON OLT-2XGS-WDM makes it easy to deploy.
Its Broadcom + NXP chipset solution ensures a robust performance. The XGSPON OLT-2XGS-WDM boasts many ports, providing 2*GE (RJ45) + 2*10GE (SFP+) uplink ports for full line-speed data forwarding. It also offers 2 XG(S)-PON downlink interfaces with a splitting ratio of 1:128 to access the user's ONT.
The Built-in WDR1r offers 2* GPON Inputs and 2* XG(S)-PON Inputs as well as 2* Combo output ports. This device is designed for use in FTTH (Fiber-to-the-Home) and small business applications the require the new higher data transfer speeds. You can still use your existing GPON OLT and link it to the OLT-2XGS-WDM GPON Input ports and combine the optical signal with the XG(S)-PON part of the OLT-2XGS-WDM. The Combo output ports can be connected to GPON and XG(S)-PON ONU’s. To use XG/XGS PON a XG/XGS PON SFP+ module is needed. The OLT can only work with a single PON mode selected either XG or XGS, The GPON port will comes a GPON OLT.

**Note**
PON ModeThe OLT-2XGS-WDM supports GPON, XG-PON or XGS-PON. For XG or XGS Select the PON mode in the Webui of the OLT and make sure the correct module is used. Only 1 mode can be used at any given time. For XG or XGS-PON the AirLive XG(S)PON OLT SFP+ N1 module must be used. To use GPON a GPON OLT needs to connected to the GPON Input Ports of the OLT-2XGS-WDM.**
Splitting RatioThe Max Splitting ratio is 1:256 for the XG/XGS OLT PON Port. But the XG/XGS PON module is currently limited to 1:128. This means only 128 XG/XGS ONU’s can be connected per PON port.
