## Long description

BlueOptics 37973177-BO cSFP fiber optic transceiver module offers single-port optical connectivity in a compact silver enclosure. The module supports a maximum data transfer rate of 1250 Mbit/s and is designed to fit into compatible SFP cages for easy installation. With a small form factor and a lightweight design of 20 g, it is intended for telecom and data networking equipment that require reliable small-form-factor optical links.
Advantages
The cSFP form factor provides a compact solution for adding fiber connectivity without occupying a full-size SFP port bay. Support for up to 1250 Mbit/s makes the module suitable for common fiber Ethernet and telecom links. Its lightweight silver housing aids heat dissipation while keeping the module easy to handle and install. The plug-and-play design is compatible with standard SFP cages, simplifying deployment in switches, routers, and media converters that accept cSFP modules.
Suitable for
 Single-port fiber uplinks in switches and routers
 Telecom and carrier access links
 Media converters and small form-factor networking equipment
 Applications requiring compact fiber transceivers with 1250 Mbit/s throughput
Key specifications
 Interface type: cSFP
 Maximum data transfer rate: 1250 Mbit/s
 Weight: 0.02 kg
 Product colour: Silver
 Form factor: Small form-factor pluggable (cSFP)
How to use
Ensure the host device supports cSFP modules before installation. With the device powered down or following the manufacturer's hot-swap guidelines, insert the BlueOptics cSFP module into a compatible SFP cage until it seats firmly. Connect appropriate fiber optic cabling to the module's optical interface, observing correct transmit and receive orientation and connector type. After insertion, verify link status on the host device and confirm the module negotiates the expected 1250 Mbit/s connection.
Usage recommendations
Handle the transceiver by the housing to avoid contaminating the optical interface; keep protective dust caps on connectors when not in use. Use clean fiber connectors and follow standard fiber handling procedures to maintain signal integrity. Verify compatibility with the host equipment and firmware to ensure proper operation at the module's rated data rate.
