## Summary description

Cudy MC100GSB-40B is a compact wired network media converter that connects copper Ethernet to single‑mode fiber. It features one RJ‑45 Gigabit port and one SC fiber port, supports 10/100/1000 Mbit/s auto‑negotiation and up to 1000 Mbit/s throughput, with a maximum fiber reach of 40,000 m. LED indicators, black housing and easy inline installation for long‑distance network extension.

## Long description

The Cudy MC100GSB-40B Gigabit Ethernet Media Converter WDM BiDi converts between copper Ethernet and fiber optic links, supporting 10/100/1000 Mbps speeds. Designed for connecting buildings or long-distance industrial control networks, this single-fiber solution supports both multi-mode and single-mode operation and uses SC fiber connectors. The A and B variants are intended to be used as a pair to establish a bidirectional single-fiber link with up to 40,000 m range.
Advantages
The media converter provides Gigabit data rates over fiber while maintaining an RJ-45 copper port for standard Ethernet devices. Its WDM BiDi design requires only one fiber strand for full duplex communication when paired (A and B units), reducing fiber infrastructure needs. The SC connector and support for both multi-mode and single-mode fibers allow flexibility for different network layouts. Its compact black housing is suitable for installation in various networking environments.
Suitable for
Connecting two buildings over long distances
Industrial control networks requiring extended fiber links
Upgrading copper Ethernet links to fiber for improved distance
Single-fiber deployments where reducing cabling is important
Key specifications
Maximum data transfer rate: 1000 Mbit/s
Ethernet LAN ports (RJ-45): 1
Fiber ports quantity: 1 (SC connector)
Supported Ethernet data rates: 10/100/1000 Mbps
Maximum transfer distance: 40,000 m

How to use
Install one A and one B variant of the Cudy MC100GSB-40B at each end of the fiber link. Connect the RJ-45 port to the local network device (switch, router, or NIC) and link the fiber ports using a single fiber strand with SC connectors. Ensure the fiber type (multi-mode or single-mode) matches on both ends and verify power and link LEDs to confirm operation. Configure connected network devices as needed for Gigabit operation.
Usage recommendations
Use the converter pair with appropriate single-mode or multi-mode fiber and SC connectors. For maximum range (up to 40 km), choose single-mode fiber and ensure proper fiber polishing and installation to minimize signal loss.
