## Long description

The BlueOptics 321-0435-BO is an SFP transceiver module intended for fiber optic network links. It supports a maximum data transfer rate of 1250 Mbit/s over multimode fiber and uses an LC fiber connector in a compact SFP form factor. The module is finished in silver and is designed for use in compatible SFP ports on switches, routers or media converters. With a specified mean time between failures (MTBF) of 1,000,000 hours, the transceiver is built for continuous network operation and predictable reliability.
Advantages
This SFP transceiver provides a standardized 1.25 Gigabit Ethernet interface for short-range fiber connections and occupies a small SFP slot without additional adapters. The LC connector ensures a common, low-loss fiber termination and the 550 m maximum transfer distance supports campus and building backbone links over multimode fiber. The silver housing and SFP form factor simplify installation and replacement in equipment racks and media converters while the high MTBF value indicates long-term operational stability.
Suitable for
Short-range multimode fiber links within buildings and campuses
Upgrading or expanding switch and router SFP ports to fiber
Media converters that require LC SFP transceivers
Network environments needing a 1.25 Gigabit Ethernet fiber interface
Key specifications
Maximum data transfer rate: 1250 Mbit/s
Maximum transfer distance over multimode fiber: 550 m
Ethernet interface: 1.25 Gigabit Ethernet
Fiber optic connector type: LC
Form factor: SFP (Small Form-factor Pluggable)
Housing colour: Silver
Reliability (MTBF): 1,000,000 hours
How to use
Install the BlueOptics SFP transceiver into a compatible SFP slot on a switch, router or media converter until it clicks into place. Connect an LC-terminated multimode fiber patch cable to the transceiver's LC connector, observing proper fiber handling to avoid bends or contamination at the connector end faces. Power on the host device and verify link status through the device management interface or LED indicators. If necessary, configure the host port for the appropriate speed and duplex settings according to the network design.
Usage recommendations
Store and handle the transceiver in a clean, dry environment; keep dust caps on connectors when not connected. Use compatible multimode fiber and ensure connector end faces are clean to maintain optimal signal quality. Verify that the host equipment supports SFP modules and the specified 1.25 Gigabit Ethernet interface before installation.
