Our Story


How can we help you?

Will using Proline optics invalidate my warranty with the Original Equipment Manufacturer (OEM)?

No. Using Proline will not void any warranty. OEMs cannot stipulate only their branded parts be used within their systems in order to retain warranty. This is supported legally by the Sherman Anti-Trust Act and the Magnuson-Moss Warranty Act.

Are Proline optics TAA compliant?

Proline offers optical transceiver solutions that are Trade Agreement Act (TAA) compliant and designated U.S. country of origin.

Where can I get a quote for products?

Simply search our website for products you are interested in, select “add to quote” and submit with your information.

Will using a Proline transceiver impact performance?

No. Proline transceivers are built to the same high standards as the OEMs, and will not impact the host systems’ performance. Multi-Source Agreement (MSA) standards ensure all transceivers adhere to defined specifications.

What is Proline’s relationship with CDW?

Proline products are exclusively available through CDW. Our long-standing partnership began in 2011. We are committed to providing high-quality connectivity solutions to our customers.

How do you ensure that I’m getting the correct part for my system?

Compatibility testing and coding is in our DNA. We have a state-of-the-art lab and testing facility with over 400 OEM switches. Each optic is coded and tested by hand to our customers' exact specifications, in the intended environment at speed and at distance - no batch testing ever. We guarantee quality assured testing on 100% of all products shipped. Test results are available to you at anytime.
