## Summary description

The LevelOne SFP-2503 is a fiber optic SFP transceiver module designed for high-speed data transfer at 2500 Mbit/s. It operates at a wavelength of 1310 nm and features a compact SFP form factor. With a typical power consumption of 1 W, it is compliant with various standards including CB, CE, FCC, RoHS, TÜV, and UL. This module is ideal for network applications requiring reliable and efficient data transmission.

## Long description

The LevelOne SFP-2503 is a single-mode SFP transceiver module designed for Gigabit Ethernet and higher-speed links. It supports bidirectional data transfer up to 2.5 Gbps over a single duplex 9/125 µm fiber core and is specified for links up to 20 km. The module uses a 1310 nm DFB laser transmitter with a PIN-TIA receiver and provides an LC duplex connector in a hot-swappable SFP form factor. Typical power consumption is 1 W and the unit complies with common safety and regulatory standards.
Advantages
The SFP-2503 offers a compact SFP package that is hot-swappable for easy installation and replacement, supports 2.5GBASE-LX single-mode operation for extended reach, and includes Digital Diagnostics Monitoring (DDM) for status and performance measurement. Its 1310 nm DFB transmitter and PIN-TIA receiver deliver stable optical performance for links up to 20 km while maintaining low typical power consumption.
Suitable for
Upgrading switches and routers to 2.5 Gbps single-mode fiber links
Long-distance fiber links within campus and metro networks (up to 20 km)
Fiber connections requiring LC duplex interfaces and SFP form factor

How to use
Power down the host device if recommended by the equipment vendor, insert the SFP-2503 module into an appropriate SFP port until it seats firmly, and secure any module latch if present. Connect duplex LC single-mode fiber patch cables (9/125 µm) observing correct transmit/receive orientation. After insertion the module is recognized by compatible network equipment and can be managed or monitored via device interfaces that support DDM.
Usage recommendations
Use certified 9/125 µm single-mode fiber and LC duplex connectors for reliable links. Verify compatibility with your switch or router vendor and enable or check DDM status for optical power and temperature monitoring. Observe the commercial operating temperature range (0 °C to 70 °C) and follow ESD precautions when handling the transceiver.
