## Long description

BlueOptics 37973274-BO is a fiber optic SFP transceiver module with a cSFP interface and a maximum data rate of 1250 Mbit/s. The module is designed for use in small form-factor pluggable slots and provides an optical link option for switches, routers and media converters. The transceiver is finished in silver, weighs approximately 20 g and is supplied as a single unit suitable for network upgrades and equipment replacement.
Advantages
The SFP transceiver supports a 1250 Mbit/s data rate over fiber, enabling reliable optical connections where copper links are impractical. Its compact small form-factor pluggable design allows hot-plug installation into compatible network ports without powering down the host device. The cSFP interface ensures mechanical compatibility with devices that accept cSFP modules, and the lightweight metal housing provides basic mechanical protection while aiding heat dissipation.
Suitable for
 Upgrading Ethernet ports on switches to fiber-based links
 Establishing optical connections between routers and switches
 Replacing faulty transceivers in media converters and network devices
 Deployments requiring small form-factor pluggable modules
Key specifications
 Interface type: cSFP
 Maximum data transfer rate: 1250 Mbit/s
 Form factor: SFP (small form-factor pluggable)
 Product colour: silver
 Weight: approximately 0.02 kg
How to use
Ensure the target device supports cSFP modules and a 1250 Mbit/s optical transceiver. Power on the host equipment, align the module with the SFP slot and insert it until it clicks into place. Connect the appropriate fiber optic cable to the transceiver's optical port and verify link status via the host device's management interface or status LEDs. To remove the module, power down the link if required by the host device’s instructions, release the module latch and extract it carefully to avoid damaging the socket or fiber connector.
Usage recommendations
Handle the transceiver by its housing, avoid touching the optical interface, and keep dust caps on the optical ports when not in use. Confirm compatibility with the host device's supported module types and firmware, and follow standard ESD precautions during installation or replacement.
