Product information

Description

The LevelOne SFP-9221 is a single‑mode bidirectional (BIDI) SFP transceiver designed for fiber‑optic networks. It supports data rates up to 1.25 Gbps over single fiber cores for distances up to 10 km, transmitting at 1310 nm and receiving at 1550 nm. The module is compatible with the SFP Multi‑Source Agreement (MSA), uses a single LC connector, requires a +3.3 V power supply, and meets EN 60825‑1 laser safety standards. It is suitable for Gigabit Ethernet and Fibre Channel applications and is CE/FCC compliant.

Advantages

The SFP-9221 provides cost‑effective bi‑directional transmission over a single fiber core, reducing fiber infrastructure needs. It supports multiple data rates from 125 Mb/s to 1.25 Gb/s with NRZ encoding, offers a standard SFP form factor for hot‑pluggable installation, and is RoHS compliant and lead‑free. Its LC connector and MSA compatibility ensure broad interoperability with network equipment that accepts SFP modules.

Suitable for

Gigabit Ethernet links up to 1.25 Gbps
Fibre Channel connections (compatible with 1.06 Gbps specifications)
Long‑reach single‑mode links up to 10 km using a single fiber core
Environments requiring hot‑pluggable SFP transceiver modules

Key specifications

Interface type: SFP (MSA compatible)
Maximum data transfer rate: 1250 Mbit/s (1.25 Gbps)
Wavelengths: TX 1310 nm, RX 1550 nm
Reach: up to 10 km over single‑mode fiber
Connector: LC (single)
Power supply: +3.3 V; max current 0.3 A
Standards: IEEE 802.3z (Gigabit Ethernet), EN 60825‑1 (LASER Class 1)
RoHS compliant, lead‑free
Weight: 0.02 kg

How to use

Insert the SFP-9221 into an SFP slot of a compatible switch, router or transceiver cage while the device is powered according to the host equipment manual. Connect a single‑mode LC patch cable to the module. For bi‑directional operation on a single fiber core, pair this TX‑1310/RX‑1550 module with a complementary SFP module that transmits at 1550 nm and receives at 1310 nm. Verify link status and data rate negotiation on the host device and observe manufacturer guidance for hot‑plug handling.

Usage recommendations

Use the SFP-9221 in matched BIDI pairs (one TX 1310 / RX 1550 and one TX 1550 / RX 1310) for single‑fiber links; confirm compatibility with your switch/vendor firmware and follow ESD and laser‑safety precautions when installing or servicing the module.
