SFP-lähetin-vastaanotin BlueOptics SFP-21AED-BO 1250 Mbit/s hopea

The BlueOptics SFP-21AED-BO 1250 Mbit/s Silver is a single‑port SFP fiber optic transceiver designed for 1.25 Gbit/s (1250 Mbit/s) optical links. Housed in a metal enclosure and weighing approximately 3 g, this compact module operates at 3.3 V and uses an LC simplex optical interface compatible with industry SFP form‑factor standards. It supports single‑mode fiber transmission using separate transmit and receive wavelengths and is intended for integration into switches, routers and other network devices that accept standard SFP modules.

Advantages

The module offers MSA‑compatible SFP form factor and a metal housing for mechanical stability and thermal dissipation. It supports 1.25 Gbit/s data rates over single‑mode fiber and includes optical transmit and receive channels for simplex LC connections. The lightweight construction and standard electrical interface make the transceiver easy to install and replace in SFP‑compatible network equipment. Where supported by host hardware, the module provides digital diagnostics (DDM/DOM) for real‑time monitoring of supply voltage, laser bias current, optical output/input power and temperature.

Key specifications

How to use

Insert the transceiver into an empty SFP port of a powered‑off or hot‑swappable host device according to the device manufacturer’s instructions until it latches. Connect an LC simplex single‑mode patch cable to the module’s optical port, ensuring correct orientation of transmit and receive fibers when linking to a corresponding transceiver. Power on the host device (or rely on hot‑swap capability) and verify link status through the device management interface. If the host supports digital diagnostics, access DDM/DOM registers to read voltage, temperature and optical power values for monitoring and troubleshooting.

Recommendations

Install the BlueOptics SFP-21AED-BO in SFP‑compatible hardware that accepts standard MSA modules and confirm host compatibility for 1000BASE‑BX‑U or 1.25 Gbit/s single‑mode applications. Use high‑quality single‑mode LC patch cords and follow connector cleaning best practices to maintain link performance. If DDM/DOM is required, ensure the host device supports the diagnostic interface to take advantage of real‑time monitoring.
