Everything You Need to Know

Find quick answers about optical transceivers, compatibility, testing and technical support.

What Is An Optical Transceiver?

An optical transceiver is a network hardware component that converts electrical data signals into optical signals for transmission over fibre, and converts incoming optical signals back into electrical data.

What types of optical transceivers do you supply?

We supply a wide range of optical transceiver form factors and configurations, including SFP, SFP+, SFP28, QSFP+, QSFP28, QSFP56, QSFP-DD, and other industry-standard solutions. Products are available for different data rates, transmission distances, wavelengths, fibre types, and networking applications.

How important is cleaning fibre connectors?

Extremely important. Dust and contamination on fibre connectors can cause high insertion loss, poor optical performance, intermittent links, or complete link failure.

Do You Offer Technical Support?

Yes. Our experienced Optical Engineers provide both pre-sales and post-sales technical support. We can assist with product selection, compatibility, troubleshooting, optical specifications, and deployment questions.
