SFP-lähetin-vastaanotinmoduuli BlueOptics SFP-GLS-W3520-A-BO 1250 Mbit/s

The BlueOptics SFP-GLS-W3520-A-BO is a fiber optic SFP transceiver module designed for 1250 Mbit/s single-mode optical links. Housed in metal and operating at 3.3 V, this compact SFP module weighs approximately 3 g and uses an SFP interface with an LC simplex optical connector. It supports 1000BASE-BX-U type point-to-point transmission over single-mode fiber, combining a 1490 nm transmitter and a 1310 nm receiver to enable bidirectional data transfer on a single fiber up to long distances as defined by the 1000BASE-BX-U application.

Advantages

The module’s metal housing provides mechanical robustness and electromagnetic shielding while the small form factor complies with SFP MSA dimensions for broad hardware compatibility. Operating at a standard 3.3 V supply and weighing only 3 g, the transceiver is easy to install and suitable for dense port environments. The device supports digital diagnostics (DDM/DOM) when the host system exposes the feature, enabling remote monitoring of key optical and electrical parameters to simplify maintenance and troubleshooting.

How to use

Insert the BlueOptics SFP-GLS-W3520-A-BO module into a compatible SFP slot on your switch, router or media converter while the host device is powered according to the manufacturer's guidance. Connect an LC simplex single-mode patch cord to the module’s optical port and route the fiber to the remote transceiver. Ensure the host device supports 1000BASE-BX-U and, if required, enable or verify Digital Diagnostics (DDM/DOM) support in the system to monitor supply voltage, laser bias current, transmit power, receive power and temperature. After insertion, verify link status and data throughput on the host device port.

Recommendations

Use single-mode LC simplex patch cords and follow the host hardware vendor’s compatibility list to ensure full functionality. Avoid touching the optical connector endfaces, keep dust caps on when not in use, and perform cleaning with appropriate fiber-optic cleaning tools to maintain signal quality. Confirm that the receiving and transmitting wavelength directions match the remote transceiver’s specification before deployment.
