SFP transceiver BlueOptics R9Q44A-BO 1250 Mbit/s 1310 nm

The BlueOptics R9Q44A-BO SFP transceiver is a compact fibre-optic module designed for duplex single-mode links at 1310 nm. It supports a maximum data transfer rate of 1250 Mbit/s and reaches transmission distances up to 10,000 m, making it suitable for metropolitan and campus networks. The module is housed in a metal casing with a standard LC connector and operates from a 3.3 V supply. With a lightweight design of approximately 20 g and an industry-standard Small Form-Factor Pluggable (SFP) footprint, it fits common switches, routers and media converters that accept SFP modules.

Advantages

The transceiver provides reliable single-mode transmission with a 1310 nm wavelength and supports long reach up to 10 km without active amplification. Its metal housing ensures mechanical durability and thermal conduction, while the LC connector offers a compact duplex interface. Low weight and the SFP form factor simplify installation and replacement in compatible network equipment. The device operates at a standard 3.3 V input, matching common SFP power requirements.

Key specifications

How to use

Ensure the host device supports SFP transceivers and is compatible with single-mode 1310 nm modules. Power down or follow hot-swap guidelines of the network equipment before inserting the module. Insert the SFP transceiver into the SFP slot until it clicks into place, then connect LC duplex fibre cable with correct polarity. After insertion, verify link status and port settings in the switch or router management interface and configure the interface speed and duplex if required. For removal, follow the equipment manufacturer's hot-swap or shutdown procedure and gently pull the module out using the release mechanism.

Recommendations

Handle the fibre connector endfaces with care to avoid contamination; always use dust caps when the transceiver is not connected. Use single-mode LC duplex fibre cable rated for the required distance and verify link parameters after installation. Operate the module within the host device’s specified temperature range and avoid exposing the metal housing to corrosive environments.
