It operates at a wavelength of 1310nm and is compatible with GSW-2453 and GVT-4000 products. This Class 1 Laser certified device ensures reliable performance with an input voltage of 3.5V and a maximum current of 0.3A. Compact dimensions of 13.5mm x 55.5mm x 8.5mm make it easy to integrate into various networking setups.

## Long description

The LevelOne SFP Transceiver 1.25Gbps 10km 1310nm is a single-mode, hot‑swappable SFP (Small Form‑factor Pluggable) module designed to add Gigabit LX fiber connectivity to compatible switches and modules. It supports a maximum data rate of 1250 Mbit/s over distances up to 10 km using a 1310 nm wavelength and a duplex LC connector. The compact transceiver is compliant with IEEE 802.3z and is powered by a single 3.3 V supply.
Advantages
This SFP transceiver provides reliable LX optical connectivity with TTL signal detection and differential LVPECL input/output for stable signal handling. It is easy to install and hot‑swappable, allowing rapid deployment or replacement without powering down equipment. The module meets Class 1 laser safety requirements and occupies a standard SFP slot for broad compatibility.
Suitable for
Adding 1000Base‑LX fiber ports to switches with SFP/mini‑GBIC slots
Connecting switches or network devices up to 10 km apart
Switch‑to‑switch uplinks and distributed multi‑processing links
High‑speed I/O file transfers and storage area network links
Key specifications
Interface type: SFP
Maximum data transfer rate: 1250 Mbit/s (1.25 Gbps)
Wavelength: 1310 nm
Maximum link distance: up to 10 km (single‑mode)
Connector: duplex LC
Power supply: single 3.3 V
Compliance: IEEE 802.3z, Class 1 Laser
Dimensions: 13.5 mm x 55.5 mm x 8.5 mm
How to use
Insert the SFP transceiver into an available SFP/mini‑GBIC slot on a compatible switch or module until it clicks into place. Connect a single‑mode duplex LC fiber patch cable between transceivers at each end of the link. Verify the link and signal status via the host device; the TTL signal detect indicator and device management will show link presence. The module is hot‑swappable, so it can be installed or removed while the host remains powered, following the host vendor's hot‑swap procedures.
Usage recommendations
Use this 1310 nm 1.25 Gbps SFP for single‑mode fiber runs up to 10 km. Ensure compatible SFP‑capable ports and confirm vendor compatibility for optimal performance. Handle the optical connector with dust caps in place when not connected and follow standard electrostatic discharge (ESD) precautions during installation.
