Tenda 1000Mbps Single-mode Single-Fiber Media Converter (TX+RX) Kit | TFC300A + TFC300B
This kit contains TWO Tenda media converters that work as a pair: one TFC300A and one TFC300B, a sender and a receiver. Together they carry a 1000Mbps Ethernet connection over a single strand of single-mode fiber for up to 3 km. Each unit has 1 Gigabit RJ45 port and 1 Gigabit SC fiber port, and converts the electrical Ethernet signal to light and back again.

Sender and receiver on one fiber: The TFC300A transmits on 1550nm and receives on 1310nm, while the TFC300B transmits on 1310nm and receives on 1550nm. Using WDM (wavelength division multiplexing), both directions travel over the same single fiber, so you need only one fiber core between the two sites instead of two. Tenda states that the TFC300A must be used together with the TFC300B, which is why they are sold here as a matched kit.

Gigabit ports: Each unit has one 1000Mbps RJ45 port for the copper network side (router, switch, camera recorder or computer) and one 1000Mbps SC port for the single-mode fiber. This lets you extend a wired Gigabit network over fiber, up to 3 km between the two units.

Plug and play: No configuration is needed. Connect the fiber between the two units, plug the Ethernet cables into the RJ45 ports, power both units on, and the link comes up. PWR, SC and LAN indicator lights on the front show power and link/activity at a glance.

6KV lightning protection and steel case: Tenda specifies lightning protection up to 6KV, and a galvanized industrial-grade steel housing for durability and heat dissipation.
Who it's for / Works with: Tenda lists 1000Mbps long-distance wired transmission for places such as hotels, universities and enterprises, including security surveillance networks with HD video.
Good to know: The two units are different models and must be used as a pair: one TFC300A at one end and one TFC300B at the other. They work with single-mode fiber only, and the maximum transmission distance is 3 km. Each unit is powered from its own power adapter (input 100–240V AC, output 5V DC 0.6A).
