## Long description

The Cudy MC100GSB-40A Gigabit Ethernet Media Converter WDM BiDi is a wired networking device that converts between copper Ethernet and fiber optic links. Supporting data rates up to 1000 Mbit/s, it offers both multi-mode and single-mode fiber operation with SC connectors and a maximum transfer distance of up to 40,000 m. The converter is intended for connecting buildings or meeting long-distance industrial control and monitoring needs and is supplied in A and B variants which must be used in pairs.
Advantages
This media converter supports Gigabit Ethernet speeds (10/100/1000 Mbps) and uses WDM BiDi technology to transmit and receive over a single fiber, reducing cabling requirements. The unit is compatible with both multi-mode and single-mode fibers and provides an SC fiber connector for straightforward installation. Its support for long-distance links (up to 40,000 m) makes it suitable for extended wired networks between sites.
Suitable for
Connecting separate buildings over fiber
Long-distance industrial control and monitoring links
Upgrading copper Ethernet segments to fiber backbone
Point-to-point Gigabit fiber connections using single-fiber BiDi

How to use
Install one A variant and one B variant at each end of the fiber link. Connect the RJ-45 Ethernet port to the local network device (switch, router, or PC) and insert the SC fiber connector into the corresponding fiber port. Power the media converter and verify link/activity LEDs to confirm the connection. Ensure the correct pairing of A and B units so the BiDi wavelengths align for transmit and receive functions.
Usage recommendations
Use single-fiber BiDi converters in pairs (A with B) and choose appropriate fiber type (multi-mode for shorter runs, single-mode for longer distances) to match the required link length and network equipment. Route fiber with proper protection and follow standard fiber installation procedures to maintain signal integrity.
