Network Media Converter PLANET GST-802S

The PLANET GST-802S is a compact network media converter that converts 10/100/1000Base-T to 1000Base-LX for long-distance fiber connections. Designed for FTTX and other fiber deployments, it supports a Gigabit Ethernet RJ-45 port and a single-mode SC fiber port (1310 nm) to extend network links up to 10,000 meters. The unit is powered by a 5V DC input and complies with FCC Class A and CE Class A standards.

Advantages

The GST-802S delivers steady Gigabit performance over single-mode fiber for long-distance links while offering plug-and-play installation. It supports auto MDI/MDI-X on the TP port and DIP-switch configurable functions such as auto-negotiation/force for the fiber interface and Link Loss Carry Forward (LLCF) / Link Loss Return (LLR) for link diagnostics and alarm. The converter can operate as a standalone unit using its DC adapter or as a slide-in module in PLANET 19-inch managed 16-slot chassis for centralized monitoring.

Suitable for

• Extending Ethernet networks over single-mode fiber for campus or metro links
• FTTX deployments requiring 1000Base-LX connectivity
• Integration into managed media converter chassis for centralized management
• Point-to-point long-distance connections up to 10,000 m

How to use

Connect the Ethernet device to the RJ-45 port and the single-mode fiber cable to the SC fiber port. Configure the DIP switch to select auto-negotiation or force mode for the fiber interface and enable or disable Link Loss Carry Forward (LLCF) / Link Loss Return (LLR) as needed. Power the unit with the supplied 5V DC adapter for standalone use or slide it into a compatible PLANET 16-slot media converter chassis to allow remote monitoring and management via the chassis interfaces.

Recommendations

For reliable long-distance links, use single-mode fiber rated for 1310 nm and ensure proper SC connector cleaning. When deploying in managed environments, install the GST-802S in the PLANET managed chassis to centralize status monitoring and alarms. Use the LLCF/LLR functions to assist in diagnosing link issues promptly.
