## Summary description

LevelOne single-mode BIDI SFP transceiver with a maximum data transfer rate of 1250 Mbit/s. Designed for fiber optic network connections over a distance of up to 10km using TX 1310nm and RX 1550nm wavelengths. Features an SFP interface and operates at an input voltage of 3.3V. Compliant with RoHS, CE, and FCC standards, ensuring reliable performance in professional network setups.

## Long description

The LevelOne SFP-9221 Single-mode BIDI SFP Transceiver is a high-performance fiber optic network component designed to deliver reliable data transfer rates of up to 1250 Mbit/s. This single-mode bi-directional transceiver utilizes a single fiber core to transmit and receive data simultaneously by using separate wavelengths, specifically transmitting at 1310nm and receiving at 1550nm. It is engineered for professional network setups requiring stable connections over distances of up to 10km, ensuring efficient and seamless communication across distributed infrastructure.
Advantages
This SFP transceiver provides significant efficiency by utilizing a single fiber optic strand for bi-directional communication, which effectively optimizes existing cabling infrastructure and reduces deployment costs. Its hot-swappable design allows for easy installation and replacement without disrupting overall network operations. Furthermore, compliance with major industry standards ensures dependable operational safety, electromagnetic compatibility, and environmental responsibility in diverse professional networking environments.
Suitable for
Extending Gigabit Ethernet network connections up to 10km over a single-mode fiber core
Connecting remote switches, routers, and enterprise network equipment
Fiber Channel applications requiring reliable data transfer at speeds up to 1.25Gbps
Upgrading existing fiber infrastructures using bi-directional wavelength division multiplexing
When it may not be suitable
This transceiver is not designed for multi-mode fiber optic cabling setups and will not function correctly if mixed with incompatible media types. Additionally, it is not suitable for ultra-long-distance network links exceeding 10km or applications requiring data transfer rates significantly higher than 1.25Gbps.
Key specifications
Fiber optic SFP interface type
Maximum data transfer rate of 1250 Mbit/s
Single-mode operation with TX 1310nm and RX 1550nm wavelengths
Maximum transmission distance of up to 10km
Input voltage of 3.3V
Single LC connector interface
RoHS, CE, and FCC compliant
How to use
To install the transceiver, gently insert it into an available SFP slot on your compatible network switch, router, or media converter until it clicks securely into place. Connect the single-mode fiber optic cable with an LC connector to the transceiver ports, ensuring the corresponding wavelengths align with the receiving equipment at the opposite end of the link. The hot-swappable capability allows the device to be inserted or removed without powering down the host hardware, though you should verify link status indicators after installation to confirm proper connection.
What to consider before purchase
Verify that your network hardware features a standard SFP slot compatible with 3.3V transceivers
Check that the opposing network device utilizes a matching complementary bi-directional wavelength configuration
Confirm that the total cable run between network points does not exceed the 10km operational limit
Ensure your infrastructure utilizes single-mode fiber cabling with an LC connector type
Usage recommendations: Always handle the optical transceiver with care and keep dust plugs inserted into the optical bore whenever the fiber cable is disconnected to prevent contamination of the optical components.
