Frequently Asked Questions - TEG311SM Tenda

Is the TEG311SM compatible with non-Tenda switches?

The module is designed to work with Tenda switches that have SFP ports, but it may also work with other switches that comply with IEEE 802.3z and support 1.25 Gbps single-mode SFP modules. However, compatibility is not guaranteed.

What is the maximum transmission distance of the TEG311SM?

The maximum transmission distance is 20 km over single-mode fiber (9/125 µm).

Does the TEG311SM support hot-plugging?

Yes, the module supports hot-plugging, meaning it can be inserted or removed without powering off the switch.

What type of connector does the TEG311SM use?

It uses a LC (Lucent Connector) interface for single-mode fiber.

What data rate does the TEG311SM support?

It supports 1.25 Gbps in full-duplex mode, suitable for Gigabit Ethernet.

How is the TEG311SM powered?

The module is powered internally by the host switch via the SFP port, requiring 3.3V supply.

What is the wavelength of the TEG311SM?

The operating wavelength is 1310 nm, which is typical for single-mode fiber transmission.

Can I use multimode fiber with this module?

No, the TEG311SM is designed for single-mode fiber (9/125 µm). Using multimode fiber will significantly reduce the transmission distance and may cause errors.

Does the module require any configuration?

The module is plug-and-play and auto-identifies itself to the switch. No manual configuration is needed.

What should I do if the module is not detected?

Ensure the module is fully inserted into the SFP port. Check compatibility with your switch. Clean the connectors with a lint-free cloth. If the issue persists, try another SFP port or replace the module.
