The OnePort programmer from Approved Networks is conveniently small and portable with proprietary software that is both intuitive and easy-to-use. OnePort takes the complexity out of coding, whether programming a single transceiver or an entire batch.


Avoid Data Center Drama

Get Higher Efficiency During Deployment

Data center operators continue looking for ways to improve efficiency in all areas. They may be searching for solutions in deployment, cooling, energy, and/or rack space usage.

The right Direct Attach Copper cables (DACs) and Active Optical Cables (AOCs) can be very helpful in obtaining these goals.

NEBS certified

We are NEBS Certified!

Approved Networks optical transceivers have undergone and passed the Network Equipment Building System (NEBS) compliance test through Intertek, the industry leader in quality assurance testing.

Our optical transceivers were put through extremes to ensure they can withstand maximal temperature, vibration, and humidity for continuous network integrity in the harshest environments.

The bandwidth monster - fiber endpoints in the data center

The Bandwidth Monster and Fiber Endpoints

Question: How do I design my fiber network based on distance and bandwidth requirements?

Larry Legg says: "When we talk fiber in the optical networking realm, we don’t mean healthy dietary supplements. Fiber-optic telecommunications technology is used for delivering broadband network access to end-customers – whether to the business or the home. That’s the easy explanation."
