TEG311SM is a single-mode optical fiber module from Tenda, built to extend LAN coverage and bandwidth over fiber optic cabling. Designed to support optical fiber transmission, this module is a practical solution for extending network coverage across large and mid-sized LAN environments where copper cabling reaches its practical distance limits.
The TEG311SM complies with the IEEE802.3z standard and operates in 1310nm mode, functioning as a 1000Base-LX single-mode SFP optical transceiver module with an LC port. This gives it a genuine 1.25Gbps transmission rate over single-mode 9/125um optical fiber, well suited for carrying full Gigabit network traffic across longer fiber runs than copper cabling can reliably support.
Full-duplex mode support means the TEG311SM can transmit and receive data simultaneously, maximizing effective throughput rather than alternating between send and receive operations. The module also supports hot-plugging and auto-identification, letting installers insert or remove it from a compatible SFP slot without powering down the switch — a genuinely convenient feature for live network maintenance and upgrades.
Designed with a small form factor, the TEG311SM is built to fit directly into a switch with an SFP port, taking up minimal physical space while extending that switch’s reach over fiber. It draws power internally from the host switch itself, meaning no separate power adapter or cabling is needed — installation is as simple as plugging the module into a compatible SFP slot.
The TEG311SM is specifically designed to match well with Tenda’s series of switches that include SFP ports, making it a natural accessory for anyone building out or upgrading a Tenda-based network that needs to bridge locations over fiber rather than copper. This is particularly valuable for connecting buildings across a campus, extending coverage to a detached structure, or linking network segments over distances that exceed standard Ethernet cable limits.
Built for durability, the TEG311SM includes ESD protection rated at ±10kV for air discharge and ±8kV for contact discharge, safeguarding the module against static electricity during handling and installation. It operates across a 0°C to 45°C temperature range and carries FCC, CE, and RoHS certification.
For network installers and IT administrators extending LAN coverage across a larger site, the TEG311SM offers a simple, cost-effective way to bridge network segments over single-mode fiber without complicating the overall network design.
