## Long description

The BlueOptics ET4202-EX-BO is an SFP transceiver module for fiber optic networks, supporting a maximum data transfer rate of 1250 Mbit/s. Designed for single-port installations in switches, routers and media converters, this lightweight silver module uses an LC fiber connector and supports link distances up to 40,000 m. With an MTBF of 1,000,000 hours, the module is intended for long-term deployment in point-to-point and extended-reach fiber connections where 1.25 Gigabit Ethernet signaling is required.
Advantages
This SFP transceiver combines compact SFP form factor compatibility with a long maximum transfer distance, enabling extended fiber links without added inline equipment. The LC connector provides a standardized, secure fiber interface while the 1250 Mbit/s data rate matches devices using 1.25 Gigabit Ethernet signaling. The module's low weight and silver housing simplify handling and installation in densely populated racks or small network appliances.
Suitable for
Point-to-point fiber links between network devices
Backbone connections in small to medium enterprise networks
Fiber connections for media converters and SFP-capable switches
Extended-reach links up to 40 km where single-mode fiber is used
Key specifications
Maximum data transfer rate: 1250 Mbit/s
Maximum transfer distance: 40,000 m
Ethernet interface type: 1.25 Gigabit Ethernet
Fiber optic connector: LC
Product colour: Silver
Weight: 0.04 kg
Reliability: MTBF 1,000,000 hours
How to use
Install the BlueOptics ET4202-EX-BO into an available SFP slot on a compatible switch, router or media converter until it latches. Connect an LC-terminated fiber patch cable to the module's LC connector, ensuring correct transmit/receive orientation and using single-mode fiber for extended distances. After physical installation, verify link status on the host device and configure interface settings according to network requirements, such as speed and duplex where applicable. Follow standard electrostatic discharge precautions during handling.
Usage recommendations
Use single-mode fiber and low-loss connectors for links approaching the maximum distance. Inspect and clean LC connectors before insertion to prevent signal degradation. Ensure the host device supports 1.25 Gigabit Ethernet SFP modules and check firmware compatibility if link negotiation fails.
