Product information

Description

The LevelOne SFP-2603 is a single‑mode fiber SFP transceiver module designed for Gigabit Ethernet and 2.5G applications. It supports bidirectional data transfer up to 2.5 Gbps over a single duplex fiber core, operates at a wavelength of 1310 nm with a DFB laser diode transmitter and PIN-TIA receiver, and uses an LC duplex connector. The module is hot-swappable and built to operate across a wide industrial temperature range.

Advantages

The transceiver delivers a combination of high performance and cost efficiency for long-reach single‑mode links up to 20 km over 9/125 μm fiber. Compliance with SFP MSA standards and support for Digital Diagnostics Monitoring (DDM) enable easy integration and real‑time status monitoring. Typical power consumption is 1 W, and the unit meets common safety and environmental certifications.

Suitable for

Metro and enterprise fiber links requiring up to 2.5 Gbps
Long‑distance single‑mode connections (up to 20 km)
Industrial environments with wide temperature ranges
Switches, routers and media converters with SFP slots

Key specifications

Data rate: up to 2.5 Gbps
Standard: 2.5GBASE‑LX single‑mode
Wavelength: 1310 nm
Transmitter: DFB laser diode; Receiver: PIN‑TIA
Connector: Duplex LC
Maximum reach: up to 20 km over 9/125 μm fiber
Operating temperature: -40 °C to 85 °C
Power consumption (typical): 1 W
Form factor: SFP (hot‑swappable); SFP MSA compliant

How to use

Insert the SFP-2603 into a compatible SFP slot on a switch, router or media converter while the host device is powered according to the equipment instructions. Connect a duplex LC single‑mode fiber patch cable (9/125 μm) to the module’s LC port, observing correct transmit/receive alignment. Monitor link status and diagnostics via the host device using DDM if supported. The module is hot‑swappable but follow your system vendor’s hot‑swap procedures to avoid transient network disruption.

Usage recommendations

Use single‑mode LC patch cables with 9/125 μm fiber and keep fiber connectors clean. Verify host compatibility with SFP MSA modules and consult the switch/router documentation for supported transceiver lists. For reliable long‑distance links, use fiber rated for 20 km and maintain proper bend radius and connector condition.
