## Summary description

The LevelOne 1.25Gbps Single-mode BIDI SFP Transceiver offers a data transfer rate of 1250 Mbit/s over a distance of 20km. It operates with a TX wavelength of 1550nm and RX wavelength of 1310nm. This SFP transceiver is compliant with safety standards EN 60825-1 and certified by CE and FCC. It features a compact design with dimensions of 57mm x 12mm x 13.7mm and operates on a voltage of 3.3V. Ideal for reliable and efficient fiber optic communication.

## Long description

The LevelOne SFP-9331 is a single‑mode BiDi SFP transceiver that supports up to 1.25 Gbps bi‑directional data transfer on a single fiber core over distances up to 20 km. It transmits at 1550 nm and receives at 1310 nm, enabling bidirectional communication when paired with a complementary transceiver. The module is compact, operates from a single +3.3 V supply, and meets applicable safety and interface standards such as EN 60825-1, IEEE 802.3z and relevant Fiber Channel specifications.
Advantages
The SFP-9331 provides cost‑effective fiber connectivity with multi‑rate support (125 Mb to 1.25 Gb), a simplex LC connector for single‑fiber links, and compliance with MSA for hot‑swappable SFP interfaces. It is RoHS compliant and designed for Class 1 laser safety, requiring no additional configuration or installation software.
Suitable for
Point‑to‑point single‑mode fiber links up to 20 km
Network equipment requiring SFP hot‑pluggable transceivers
Gigabit Ethernet and Fibre Channel uplinks and connections

How to use
Install the SFP‑9331 into a compatible SFP port on switches, routers or media converters while the host device is powered down or hot‑swap capable. For bi‑directional single‑fiber operation, pair this transceiver with the complementary module (e.g., SFP‑9321) that uses the opposite TX/RX wavelengths. Connect the simplex LC fiber patch cable, verify link status on the host device, and ensure the host provides a +3.3 V supply to the SFP slot.
Usage recommendations
Use certified single‑mode fiber and LC simplex patch cords, confirm compatibility with the host device vendor’s SFP support list, and avoid bending the fiber beyond recommended radii. For long‑term reliability, operate within the specified temperature and power limits and follow ESD handling procedures when inserting or removing the module.
