## Summary description

The BlueOptics 3CSFP91-BO is a fiber optic SFP transceiver module operating at 850 nm. It features an LC connector and is compliant with RoHS standards. Weighing only 20 g, it is compatible with CE and FC products, making it suitable for various networking applications.

## Long description

The BlueOptics 3CSFP91-BO is an SFP fiber optic transceiver module designed for short-range multimode optical links. Operating at a wavelength of 850 nm, it uses an LC duplex connector and conforms to RoHS. With a compact, lightweight metal housing and a standard SFP interface, this module integrates into compatible network equipment to provide 1.25 Gbit/s optical connectivity for Ethernet and related applications.
Advantages
The transceiver offers a small form factor SFP interface that fits standard SFP ports and supports proven multimode 850 nm optical transmission. Its LC connector provides reliable duplex fiber connections while the silver metal housing contributes to mechanical durability and thermal dissipation. Compliance with RoHS and compatibility with CE and FCC products ensure it meets common regulatory and interoperability expectations for network hardware.
Suitable for
 Short-range multimode fiber connections in switches and routers
 1 Gbit/s Ethernet uplinks and server connections
 Patch panel or fiber patch cord connections using LC duplex
 Network equipment requiring standard SFP transceivers
Key specifications
 Interface type: SFP (small form-factor pluggable)
 Optical wavelength: 850 nm
 Connector type: LC duplex
 Supported data rate: up to 1.25 Gbit/s (typical for 1000Base-SX class modules)
 Media: multimode fiber
 Weight: 0.02 kg
 Housing colour: silver metal
 Standards compliance: RoHS; compatible with CE and FCC-regulated equipment
How to use
Insert the BlueOptics SFP module into a compatible SFP port on your switch, router or network device until it latches. Connect an LC duplex multimode fiber patch cord between this transceiver and the remote transceiver or patch panel, ensuring correct transmit/receive orientation. After insertion and fiber connection, verify link status in the host device and configure the port for the intended protocol and speed if required. For removal, release the SFP latch and gently pull the module out of the slot.
Usage recommendations
Use standard OM1/OM2/OM3 multimode fiber appropriate for 850 nm transmission and keep dust caps on connectors when not connected. Ensure the host device supports SFP modules and, if applicable, Digital Diagnostics Monitoring (DDM/DOM) features to monitor optical parameters. Store and handle the transceiver in ESD-safe conditions and follow manufacturer guidance for insertion and removal to avoid connector damage.
