## Summary description

The BlueOptics 6GK59921AL008AA0 is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s and operates at a wavelength of 850 nm. It is designed for high-speed data communication in network environments, ensuring reliable connectivity and performance. This module is ideal for use in various networking applications where fiber optic connections are required.

## Long description

The BlueOptics 6GK59921AL008AA0 SFP transceiver module is a compact fiber optic interface designed for short-range multimode links. Supporting a maximum data transfer rate of 1250 Mbit/s and operating at an 850 nm wavelength, this SFP fits standard SFP slots and provides a reliable optical connection for switches, routers and other network equipment that accept hot-swappable SFP modules. The module is intended for use in data center uplinks, enterprise LAN segments and other network environments where fiber connectivity and reduced electromagnetic interference are required.
Advantages
This SFP transceiver offers standardized SFP form factor compatibility and a 1250 Mbit/s nominal data rate suitable for legacy and certain current Gigabit applications. The 850 nm wavelength is optimized for multimode fiber, ensuring low-friction physical integration and consistent optical performance over short distances. Hot-swappable design allows replacement or upgrade without powering down host equipment, supporting minimal downtime and straightforward maintenance.
Suitable for
Short-range multimode fiber links in data centers and server rooms
Gigabit Ethernet connections that accept SFP modules
Upgrading or replacing optical ports on switches and routers
Redundant uplinks and network segmentation in enterprise LANs
Key specifications
Interface type: SFP form factor
Maximum data transfer rate: 1250 Mbit/s
Wavelength: 850 nm (optimized for multimode fiber)
Application range: short-range multimode fiber links
Hot-swappable optical transceiver designed for standard SFP cages
How to use
Insert the BlueOptics SFP transceiver into an empty SFP port on a compatible switch, router or media converter until it clicks into place, ensuring correct orientation. Connect the multimode fiber patch cable with the appropriate connector (e.g., LC) to the transceiver’s optical interface. Check link status and diagnostics via the host device management interface and verify that the port is configured for the intended speed and duplex settings. To remove, release any retention mechanism and pull the module straight out while the system is powered if the host supports hot-swap.
Usage recommendations
Use multimode fiber (OM1/OM2/OM3/OM4 as supported by your network design) rated for 850 nm operation and maintain proper fiber cleanliness. Verify compatibility with the host device’s SFP acceptance policy and confirm link settings after installation. Avoid exposing the optical port to contaminants and store unused modules with dust caps installed.
