SFP fiber transceiver Extralink EX.8024 — 1.25Gbps, single-mode 1550nm, LC/UPC, 80 km, DOM

Extralink EX.8024 is an SFP fiber transceiver designed for single-mode networks with a data rate up to 1.25 Gbit/s. The module transmits at 1550 nm and uses an LC/UPC duplex connector to support long-distance links up to 80 km over single-mode fiber. It integrates a DFB laser and a PIN photodetector, supports digital optical monitoring (DOM) for real-time diagnostics and complies with relevant SFP MSA and SFF-8472 standards as well as RoHS and FCC requirements. The transceiver operates from a nominal input voltage in the range of 3.13–3.47 V with a maximum current draw of 0.3 A.

Advantages

The Extralink EX.8024 offers reliable long-reach connectivity with a compact SFP form factor compatible with standard networking equipment. Built-in DOM provides monitored parameters such as optical power and temperature to assist with remote diagnostics. The module uses a DFB laser for stable transmission at 1550 nm, ensuring lower attenuation and extended reach on single-mode fiber. Compliance with SFP MSA and industry standards ensures interoperability with a wide range of switches and routers.

How to use

Install the Extralink EX.8024 into an available SFP slot on compatible networking equipment while the device is powered down or following the equipment vendor's hot-swap procedure. Connect LC/UPC duplex single-mode fiber patch cords ensuring correct TX/RX polarity. Verify the link status and monitor DOM parameters via the host device management interface to confirm optical power, temperature and other diagnostics. Ensure the equipment port is configured for the appropriate speed and duplex mode if manual configuration is required.

Recommendations

Use low-loss single-mode fiber and clean LC connectors to maintain the specified reach; check link budget before deployment. Avoid bending fiber beyond recommended minimum bend radii and operate the module within the specified voltage and current limits. For carrier or critical links, monitor DOM values regularly and keep firmware of host devices up to date for best interoperability.
