Media converter TENDA TFC300B WDM Tx 1310nm Rx 1550nm 3 km

TENDA TFC300B WDM Tx 1310nm Rx 1550nm 3 km is a single-fiber media converter designed to convert 10/100 Ethernet signals between copper and fiber networks using wavelength-division multiplexing. The unit transmits optical signals at 1310 nm and receives at 1550 nm, enabling a full duplex link over a single optical fiber for distances up to 3 km. It is intended for extending Ethernet connectivity where laying a single fiber is necessary or preferred, offering a compact solution for small offices, branch sites, campus buildings, and other short-reach fiber interconnects.

Advantages

The converter supports single-fiber WDM operation to reduce fiber infrastructure requirements while maintaining separate transmit and receive wavelengths. It provides transparent conversion between 10/100 Mbps copper Ethernet and fiber optics, preserving existing network protocols and devices. Its small form factor and straightforward installation minimize space and setup complexity. The device operates over a practical short-range distance of up to 3 km, suitable for many local interconnection scenarios.

Suitable for

• Extending Ethernet connections between buildings across a single optical fiber
• Connecting switches, routers, or surveillance cameras to a fiber backbone
• Small office or campus network interconnects where single-fiber runs are available
• Upgrading copper links to fiber without replacing end-network equipment

Key specifications

• Fiber mode: Single-mode fiber (SMF)
• Transmit wavelength: 1310 nm
• Receive wavelength: 1550 nm
• Maximum link distance: up to 3 km
• Copper port: 10/100 Mbps RJ-45 Ethernet
• Fiber connector type: compatible with standard single-fiber connectors (check local cabling)
• Data rate: 10/100 Mbps Ethernet

How to use

Install the TENDA TFC300B near the copper Ethernet device and connect the RJ-45 port to the switch, router, or IP camera using standard Ethernet cabling. Terminate the fiber side to the single optical fiber network using the appropriate connector and ensure the paired converter at the remote end matches the complementary wavelengths (Tx 1310 nm / Rx 1550 nm). Power the device using the supplied adapter and verify link LEDs for proper connection. For best results, confirm fiber continuity and loss budgets for the intended 3 km span before finalizing installation.

Usage recommendations

Use the converter in temperature-controlled indoor environments and within specified operating conditions. When deploying over existing fiber, check for splices, bends, and connectors that may introduce attenuation. For critical links, perform optical power testing and keep spare converters or adapters to minimize downtime during maintenance.
