Suitable for
Connecting switches and routers in enterprise local area networks
Data center server interconnects requiring multimode fiber links
Telecommunication infrastructure applications utilizing SFP interfaces
1000Base-SX Ethernet and dual-rate Fibre Channel environments
When it may not be suitable
This module is not designed for long-distance telecommunication links exceeding 550 meters, as it is optimized for shorter reach multimode fiber applications. It is also incompatible with single-mode fiber optic cabling infrastructures and equipment that does not support SFP transceiver slots.
Key specifications
Fiber optic SFP transceiver type
Maximum data transfer rate of 1250 Mbit/s
Operating wavelength of 850 nm
LC fiber optic connector interface
Maximum transfer distance of 550 meters
Input voltage of 3.3 V
Typical power consumption of 1 W
How to use
To install the transceiver, ensure that the network device is powered off or supports hot-swapping according to manufacturer guidelines. Gently slide the module into the designated SFP slot until it clicks securely into place. Remove the protective dust cap from the optical bore and connect the appropriate LC fiber optic patch cable. Verify that the link status indicators on your networking equipment show a successful connection before initiating data transmission.
What to consider before purchase
Verify compatibility with your existing network switches, routers, or media converters
Confirm that your cabling infrastructure consists of matching multimode fiber with LC connectors
Check the required transmission distance to ensure it falls within the 550-meter limit
Ensure that optical connectors are thoroughly cleaned before insertion to prevent signal degradation and maintain optimal network performance.
