Converts 10/100BASE-TX copper to 100BASE-FX multi-mode fibre over SC connectors up to 2 km
The PLANET FT-802 converts 10/100BASE-TX twisted-pair signals to 100BASE-FX multi-mode fibre over a SC connector. It operates at a 1310 nm wavelength and supports link distances up to 2 km. The unit includes an auto-MDI/MDI-X RJ45 port and an external 5 V DC power adapter.
Technicians who need to bridge copper segments beyond the 100 m limit will find the 2 km fibre reach suitable. The converter auto-negotiates duplex mode and provides LED indicators for power, link and activity on both ports. It is not intended for Gigabit or 10 Gigabit backbones, nor for single-mode fibre deployments.
The fibre interface uses a SC connector on 62.5/125 µm or 50/125 µm multi-mode cable rated for 2 km. Transmitter launch power ranges from -20 dBm to -14 dBm depending on core size, while receiver sensitivity is -31.8 dBm. This optical budget determines whether the link meets the required distance.

The converter operates from 0 to 50 °C and draws a maximum of 5 V DC at 2 A from its external AC adapter, so heat output stays within those limits.
You need multi-mode fiber with SC connectors; the unit transmits at 1310 nm and is rated for 2 km over 62.5/125 µm or 50/125 µm cable.
Yes, the twisted-pair port is 10/100 Mbps with auto-MDI/MDI-X and auto-negotiates down to 10BASE-T half-duplex when connected to legacy hubs.
