The Planet FT-80x series Fast Ethernet Bridge converters offer a quick, efficient and inexpensive solution for conversion between 100BASE-FX fiber and 10/100BASE-TX shielded twisted pair (STP). These converters accept various types of Ethernet Media on an RJ-45 port, and the fiber port of the converters operates at 1310 nm and uses ST, SC, MTRJ, VF45 or WDM connectors. Multi-mode models that support distances up to 2km and single-mode models that support distances up to 15/20/35/50/60km are available. Plus, these converters are built with metal housing with anti-corrosion treatment, ensuring reliable strength and durability to withstand harsh environments.

Auto Adaptability
The converter auto-adapts to the highest level of performance supported by the device connected to the STP port. When the device is a switch or a workstation that supports full duplex, the converter adapts to the full-duplex mode and provides an effective 200Mbps bandwidth. When the connected device is a hub or a workstation that supports only half duplex, the converter adapts to the half-duplex mode and provides the nominal 100Mbps bandwidth. An override switch provides total manual control over the half/full-duplex operation in fiber-optic interface.
Enhanced Management
The FT-80x series is with LFP (Link Fault Pass-through function which includes LLCF and LLR) and the DIP switch design. LLCF/LLR can immediately alert administrators to the problem of the link media and provide efficient solution to monitoring the net. The DIP switch provides the disabling or enabling of the LFP function
LLCF (Link Loss Carry Forward) means when a device is connected to the converter and the TP line loses the link, the converter's fiber will disconnect the link of transmission. LLR (Link Loss Return) means when a device is connected to the converter and the fiber line loses the link, the converter's fiber will disconnect the transmission link. Both can immediately alert administrators to the problem of the link media and provide efficient solution to monitoring the net.
Applications
Standalone and Centralized Management Media Converter Installation
To meet the demand for the growing network, PLANET FT-80x has provided the advanced media conversion technology. The FT-80x media converter provides various fiber connecting types to meet different network applications. It is very flexible for the FT-80x to work as a standalone device or to be installed into the central standard media converter chassis for providing centralized power. The FT-80x is an ideal solution to building a network solution of FTTH (Fiber to the Home) or FTTC (Fiber to the Curb) and FTTB (Fiber to the Building) for ISPs, campuses and enterprises.

The PLANET FT-802S35 is a 10/100BASE-TX-to-100BASE-FX media converter for connecting an Ethernet device with an RJ45 port to a single-mode fiber link up to 35 km, making it suitable for extending 10/100 Mbps network connections over long distances.
Recommended For
- Network installers extending a 10/100 Ethernet connection between buildings or campus locations over an existing single-mode fiber link with SC connectors, where a 100 Mbps fiber link is sufficient.
- ISPs or enterprise network teams connecting a copper Ethernet device to a 100BASE-FX fiber path for FTTH, FTTC, or FTTB deployments that need a standalone media converter.
- Installers replacing a copper segment with a fiber run of up to the model’s specified 35 km, when both ends have compatible single-mode SC equipment and the link does not need gigabit throughput.
- Organizations deploying several compatible PLANET converters that want individual units powered by adapters or installed in a PLANET media-converter chassis for centralized power.
Real-World Use Scenarios
- Connecting two Ethernet network segments across an existing single-mode fiber run: use a compatible 100BASE-FX connection at the far end to carry traffic between copper Ethernet equipment at each end, up to the link’s supported distance.
- Linking a branch office or separate building to a main site over single-mode fiber: the converter bridges a local 10/100 Ethernet connection to the fiber link, providing a practical option for existing Fast Ethernet equipment.
- Extending a campus or enterprise network beyond a copper Ethernet segment: connect a switch or workstation to the RJ45 side and carry the connection over compatible single-mode fiber, rather than relying on a long copper run.
- Adding fiber links in a central wiring closet: install the converter in a compatible PLANET media-converter chassis to consolidate multiple links and power them centrally; this suits sites managing several copper-to-fiber connections.
- Connecting older 10/100 Ethernet equipment to a fiber-based network: the converter provides a copper-to-fiber bridge without requiring the endpoint to have a built-in fiber port, while the connection remains limited to Fast Ethernet rates.
