The module features a metal housing for durability and operates at an input voltage of 3.3 V. Weighing only 20 g, it is lightweight and easy to install in various networking applications.

## Long description

The BlueOptics B239-BO 1250 Mbit/s SFP 1550 nm is a compact fiber optic transceiver module designed for single-port SFP slots. It supports a maximum data transfer rate of 1250 Mbit/s at a 1550 nm operating wavelength and is housed in a metal casing that provides mechanical protection and electromagnetic shielding. The module requires a 3.3 V input supply, has a lightweight design of approximately 20 g and a silver finish, making it suitable for use in a variety of network equipment where reliable optical links are needed.
Advantages
The module's metal housing improves durability and helps with thermal dissipation while the SFP form factor ensures compatibility with many switches, routers and media converters that accept hot-pluggable SFP modules. With a specified data rate of 1250 Mbit/s and operation at 1550 nm wavelength, it supports standard fiber network links over longer distances where the 1550 nm band is preferred. The compact, lightweight design simplifies installation and reduces mechanical strain on SFP ports.
Suitable for
 Point-to-point fiber links in enterprise and carrier networks
 Optical uplinks between switches and routers
 Use in media converters and SFP-compatible network appliances
 Environments requiring a 1550 nm wavelength for extended reach

How to use
Insert the BlueOptics B239-BO module into a compatible SFP slot on your network device while the device is powered according to the manufacturer's hot-plugging guidelines. Ensure the device supports a 1250 Mbit/s SFP transceiver at 1550 nm and verify connector type and fiber type match your cabling (single-mode fiber is typically used at 1550 nm). After insertion, connect the optical fiber connector securely and confirm link status via the network device interface or status LEDs. Follow any device-specific configuration required for enabling the optical port.
Usage recommendations
Handle the transceiver by the housing, avoid touching optical interfaces, and use protective caps when the module is not connected. Ensure cleanliness of fiber connectors and follow ESD precautions during installation. Verify compatibility with your network equipment's SFP specifications before deployment and consult device documentation for supported wavelength and data-rate settings.
