## Long description

The AddOn Networks GLC-SX-MMD-AO fiber optic transceiver module is a compact SFP solution designed for 1 Gbit/s Ethernet links over multimode fiber. Operating at a wavelength of 850 nm and fitted with an LC connector, this module supports multi-mode fiber runs up to 550 meters and is built to meet MSA (Multi-Source Agreement) interoperability standards. The module is fully functionally tested and certified by UL and cUL for reliable performance and compatibility with CISCO products.
Advantages
This SFP transceiver provides a standardized SFP interface and OEM-compatible initialization, enabling drop-in replacement or mixed deployment with Cisco and other compatible transceivers. Its compact form factor and industry-standard electrical and optical characteristics allow easy installation in switches and routers that accept SFP modules. Factory-loaded configuration data and full functional testing reduce integration risks and ensure predictable network behavior.
Suitable for
 1 Gbit/s multimode fiber Ethernet links
 Network switch and router SFP ports requiring Cisco-compatible optics
 Campus, enterprise and data center horizontal links up to 550 m
 Replacement or spare transceiver inventory for mixed-vendor networks
Key specifications
 Interface type: SFP (small form-factor pluggable)
 Maximum data transfer rate: 1000 Mbit/s (1 Gbit/s)
 Wavelength: 850 nm for multimode fiber
 Maximum reach: up to 550 meters over multimode fiber
 Connector type: LC duplex
 Compliance: MSA-compatible optical and electrical specifications
 Certifications: UL and cUL
 Dimensions (W×D×H): 13.7 mm × 56.5 mm × 18 mm
How to use
Install the AddOn GLC-SX-MMD-AO by inserting the SFP module into an empty SFP port until it latches, and connect LC-terminated multimode fiber patch cables to the module. Verify the host device recognizes the module and negotiates the 1 Gbit/s link. Ensure both ends of the link use compatible multimode fiber and that patch cords are clean and undamaged. When removing, depress the latch and pull the module straight out to avoid damaging the cage or connector.
Usage recommendations
Use this module in equipment that explicitly supports SFP optics and Cisco-compatible transceivers. Maintain cleanliness of LC connectors, avoid bending fiber beyond recommended radii, and store spare modules in anti-static packaging when not in use. For reliable operation, match multimode fiber type and link length to the specified reach and consider testing links after installation.
