ComNet Fiber Optic and Ethernet Transmission Equipment is Setting the Standard for Value and Performance.

ComNet is a major provider of video, audio and data transmission and network communication solutions for the security market.

Currently the product line is focused on two different forms of fiber optic transmission.

First is the traditional point-to-point fiber optic method of transmitting video, audio and data over multimode or single mode fiber optic cables. The second method is Fiber Optic Ethernet.
All ComNet products are designed for use in tough industrial environments and are backed with the ComNet exclusive lifetime warranty.


ComNet fiber optic video products can transmit up to 32 individual video feeds over one optical fiber plus camera control data. ComNet offers multiple models from economical AM modulated video to high quality digital video. The main benefits to video over fiber include, longer distances, immunity from EMI/RFI as well as bandwidth to transmit multiple video feeds over a single optical fiber.

Access Control

ComNet fiber optic data transmission products are used to the transport RS-232, RS-422 and RS-485 serial data that is commonly used for many Access Control Systems. Some of the many benefits to serial data over optical fiber include increased distances and immunity to EMI/RFI. Products for these applications include serial data (RS-232/RS-422/RS-485) point-to-point, linear add-drop/point-to-multipoint, and self-healing ring transmission equipment.


ComNet offers fiber optic audio transmission products that can transmit balanced line-level 24-bit digitally encoded audio. The product line includes two bi-directional audio channel with contact closure and four-channel audio with bi-directional contact closure models.


Ethernet-based security networks perform a critical role in security; therefore, the highest level of control and management must be achieved to keep the network functioning optimally. Managing the devices on the network is an important element. No matter whether it is the network infrastructure or the devices connected to it – the cameras, switches, servers and more – that are the nodes on the network, reliability is critical.

ComNet has a complete line of environmentally hardened Ethernet transmission equipment that included CAT 5/6 electrical to optical media converters, CAT 5/6 to coaxial cable/UTP media converters to increase distances or utilize existing transmission media as Ethernet transmission media and wireless Ethernet products and cellular radio Ethernet products..

ComNet also offers RS-232,422 and RS-485 data to Ethernet converters and contact closure to Ethernet products.

The switch line includes five to twenty-eight port managed Ethernet switches with and without power over Ethernet (PoE). Many Comnet switches are now made in the USA. ComNet also offers a line of 10/100 Mbps and 1000 Mbps unmanaged four and eight-port switches to round out the product line.

Security demands continuous, dependable network functionality. ComNet is so confident in the performance of our Ethernet products, we can back them with a no-questions-asked Lifetime Warranty.
