# TP-Link GPON OLT SFP optical module | TP-DS-PMA-C++

The TP-Link TL-SM331T is a Class C++ GPON OLT SFP optical transceiver module designed for use in Optical Line Terminals (OLTs) within a Gigabit Passive Optical Network. It establishes a high-speed, long-distance PON connection from the OLT to multiple Optical Network Units (ONUs). This SFP module operates with a downstream data rate of 2.5 Gbps and an upstream data rate of 1.25 Gbps over a single-mode fibre optic cable. The Class C++ optics provide a high power budget, making it suitable for deployments requiring extended reach and a higher subscriber split ratio. It is equipped with a standard SC/UPC connector for direct connection to fibre optic cabling and is hot-pluggable for installation without service interruption. The module supports Digital Diagnostic Monitoring (DDM) for real-time tracking of operational parameters. Key Specifications: \*   Module Type: GPON OLT SFP \*   Optical Class: C++ \*   Data Rates: 2.5 Gbps Downstream / 1.25 Gbps Upstream \*   Connector: SC/UPC \*   Fibre Type: Single-Mode Fibre (SMF) \*   Standards: Compliant with ITU-T G.984.2 \*   DDM/DOM: Supported \*   Compatibility: Designed for TP-Link GPON OLTs
