## Long description

The BlueOptics 551091-BO SFP transceiver module is a compact fiber optic transceiver designed for single-mode applications with a maximum data transfer rate of 1250 Mbit/s. It supports the SFP interface standard and operates from a 3.3 V supply. The module is constructed in a small metal housing with a silver finish and lightweight design, making it suitable for use in switches, routers and other networking equipment that accept SFP form-factor modules.
Advantages
The module offers a standardized SFP interface and a small form factor that simplifies deployment in dense networking environments. Its single-mode optical design with LC simplex connectivity supports point-to-point links at gigabit-class speeds over long distances while remaining impervious to electromagnetic interference. The transceiver’s compact dimensions and low weight enable straightforward installation and hot-plug replacement in compatible systems.
Suitable for
Single-mode fiber gigabit Ethernet links
Interconnects between switches and routers supporting SFP modules
Fiber runs in data centers and telecom access networks
Replacement or upgrade of existing SFP transceivers in compatible hardware
Key specifications
Interface type: SFP
Maximum data transfer rate: 1250 Mbit/s
Supply voltage: 3.3 V
Connector type: LC simplex (single-mode optical)
Housing colour: silver; lightweight metal housing (approx. 0.02 kg)
Compact dimensions: approximately 13.9 mm (W) × 58.4 mm (D) × 12.6 mm (H)
How to use
Insert the SFP transceiver into a compatible SFP slot on the host device while the device is powered according to the vendor’s hot-plug guidance. Connect an appropriate single-mode LC simplex patch cable to the transceiver’s optical port and verify link status on the host equipment. Ensure the host hardware supports the module’s SFP form factor and the required optical signalling. For access to diagnostic data, enable any available DDM/DOM support on the host platform if supported by both the transceiver and hardware.
Usage recommendations
Use single-mode LC simplex patch cords and ensure proper end-face cleanliness before making connections. Verify compatibility with the host device firmware or vendor compatibility list and avoid inserting or removing the module under mechanical stress. Store unused transceivers in antistatic packaging and protect optical ports with dust caps when not connected.
