SKU CH-M7H9-T797N

A managed Gigabit fibre-to-fibre converter module linking two 1000BASE-SX 850 nm multimode ST ports up to 550 m

  • TypeData & Communication
  • Managed fiber conversion for flexible network deployment
  • Gigabit throughput at 1000 Mbps for high-speed links
  • Dual 850 nm multimode ST ports for consistent connectivity
  • 550 m reach per port extends building-scale runs
  • 1804 ft distance rating matches 550 m specification

Managed Fiber Converter Module

The Perle CM-1000MM-M2ST05 is a managed Gigabit fiber-to-fiber converter module designed for network operators extending multimode links. It converts 1000BASE-SX 850 nm signals on ST connectors to the same standard on the far end. The module supports managed or unmanaged operation for flexible deployment.

Installation and Common Issues

The unit installs into a compatible Perle chassis slot without tools and operates immediately in unmanaged mode. Managed features require configuration through the chassis management interface which may need firmware alignment. A frequent issue is mismatched ST patch cords causing link faults on the 850 nm path.

Distance Headroom and Limits

Each 1000BASE-SX segment reaches 550 m or 1804 ft over 850 nm multimode fiber. The converter simply regenerates the signal so total distance equals the sum of both segments. Beyond 550 m per side the optical budget is exhausted and errors rise sharply.

Questions about this item

How can I confirm the CM-1000MM-M2ST05 is operating correctly after installation?

The module supports managed operation; check the management interface for link status on both 1000BASE-SX 850nm multimode ST ports and verify each shows a 550 m or 1804 ft reach.

What comes in the box with the CM-1000MM-M2ST05 and what must I purchase separately?

The product is a managed Gigabit fiber-to-fiber converter module; ST patch cables and a compatible chassis or power supply are not included and must be sourced separately.

Which version of the CM-1000MM-M2ST05 should I choose for my multimode fiber run?

This model provides dual 1000BASE-SX 850nm multimode ST interfaces rated for 550 m or 1804 ft; select it when both ends use the same multimode ST connection.
