## Long description

VALUE SFP module 21.99.3500 is a multimode small form-factor pluggable transceiver that supports 1G and 1.25G data rates and includes Digital Diagnostic Monitoring (DDM). It is designed for insertion into standard SFP ports on switches, routers and media converters to provide short-reach fiber connectivity. The module enables hot-swap installation and supplies real-time diagnostic information on optical power, temperature and other operational parameters via DDM.
Advantages
This SFP module supports both 1G and 1.25G speeds on multimode fiber, offering backward and forward compatibility for network equipment that requires those data rates. Integrated DDM provides continuous monitoring of key optical and device parameters to assist with troubleshooting and predictive maintenance. The form factor is industry-standard for SFP ports and allows tool-free hot insertion and removal, simplifying upgrades and replacements in live networks.
Suitable for
 Short-reach fiber links between switches and servers within data centers or server rooms
 Campus and enterprise network uplinks and distribution links over multimode fiber
 Media converters and legacy equipment requiring 1G/1.25G SFP transceivers
Key specifications
 Multimode fiber transceiver supporting 1.0 Gbit/s and 1.25 Gbit/s line rates
 Small Form-factor Pluggable (SFP) package for standard SFP ports
 Digital Diagnostic Monitoring (DDM) for optical power, temperature and related diagnostics
 Designed for short-reach multimode fiber links
 Hot-swappable installation
How to use
Install the VALUE SFP module into an available SFP port on a compatible switch, router or media converter until it clicks into place. Connect a multimode fiber patch cable to the transceiver and ensure the far-end device is configured for matching data rate and duplex settings. Monitor the transceiver status and diagnostic parameters via the network device management interface that exposes DDM information to verify optical levels and operational temperature. Remove the module by pulling the release tab or latch while the host device supports hot-swap removal.
Usage recommendations
Use multimode OMx-rated fiber and appropriate patch cords for short-reach connections; verify link settings on both endpoints to match 1G or 1.25G rates. Regularly check DDM readings after installation and during maintenance windows to detect degradation in optical power or abnormal temperature conditions.
