SFP transceiver module BlueOptics EMA2G-LD3TA-MT-BO 1250 Mbit/s

The BlueOptics EMA2G-LD3TA-MT-BO is an SFP fiber optic transceiver module designed for 1000Base-SX multimode fiber links and a maximum data rate of 1250 Mbit/s. Housed in a silver SFP enclosure, it implements LC Duplex connectivity and MSA-compliant electrical and optical interfaces for broad compatibility with switches, routers, storage systems and other networking hardware. The module supports simultaneous transmit and receive operation using 850 nm laser optics and is compatible with devices that accept standard SFP 1.25 Gbit/s multimode transceivers.

Advantages

The module offers a compact SFP form factor with low weight (approx. 20 g) and standard LC Duplex fiber connections for easy installation and hot-plug replacement. Manufactured to MSA-compatible specifications and assembled from proven optical and IC components, it delivers reliable operation, long service life and stable optical performance. Built-in digital diagnostics (DDM/DOM) provides real-time monitoring of parameters such as supply voltage, laser current, transmitted and received optical power and temperature when supported by the host equipment.

How to use

Insert the EMA2G-LD3TA-MT-BO module into a compatible SFP port on the powered-off or hot-pluggable network device until it clicks into place. Connect LC Duplex multimode patch cables to the transceiver’s LC ports, ensuring correct TX/RX orientation. If the host device supports digital diagnostics, enable or query the DDM/DOM interface via the management system to monitor optical power, temperature and supply parameters. Use compatible transceiver settings on your switch or router to configure link speed and duplex as required by the network.

Recommendations

Use multimode fiber and matching LC Duplex patch cables rated for 850 nm to achieve the specified reach and performance. Verify host device compatibility and firmware support for third-party SFP modules if required. For reliable long-term operation, avoid mechanical stress on the fiber connectors, protect unused ports with dust caps, and perform periodic optical power and DDM checks as part of routine network maintenance.
