Sieťový mediakonvertor PLANET FST-802

The PLANET FST-802 is a network media converter that converts between 10/100BASE-TX copper Ethernet and 100BASE-FX fiber optic connections. It features a 10Base-T / 100Base-TX TP port and a 100Base-FX SC multimode fiber port operating at 1310 nm, supporting transmission distances up to 2 km. The device supports data rates up to 100 Mbit/s, is FCC and CE certified, and is powered by a 5 V, 2 A DC adapter.

Advantages

The FST-802 extends Ethernet links over fiber to increase distance and reduce electromagnetic interference. It supports auto MDI/MDI-X on the TP port and uses a store-and-forward mechanism to prevent forwarding of faulty packets. DIP switch configuration allows manual selection of duplex and speed modes and enables smart functions such as Link Loss Return (LLR) and Link Loss Carry Forward (LLCF) for timely link-failure alerts. The unit can operate as a standalone converter or as a slide-in module in PLANET 19-inch media converter chassis for centralized monitoring.

Suitable for

• Extending 10/100 Mbps Ethernet links over multimode fiber up to 2 km
• Connecting copper-based network equipment to fiber infrastructure
• Deployments requiring EMI immunity or isolation between network segments
• Standalone installations or integration into PLANET media converter chassis

Key specifications

• Model: PLANET FST-802
• TP Interface: 10Base-T / 100Base-TX (RJ-45), auto MDI/MDI-X
• Fiber Interface: 100Base-FX SC, multimode, 1310 nm
• Maximum fiber distance: up to 2 km (multimode)

How to use

Install the FST-802 by connecting the copper Ethernet device to the RJ-45 TP port and the fiber optic cable to the SC port. Power the unit with the supplied 5 V DC adapter. Use the DIP switches to set duplex and speed modes or leave auto-negotiation enabled. If used within a PLANET media converter chassis, slide the module into an appropriate slot and monitor its status via the chassis RS-232 console or web interface.

Recommendations

For reliable links, use multimode fiber of appropriate grade and ensure connectors are clean. Verify DIP switch settings match the connected device (speed and duplex). When integrating into a chassis, confirm firmware and chassis compatibility for remote monitoring.
