Business Segments Description


Transition Networks designs, assembles and sells media converter devices, NIDs, Ethernet switches and other connectivity products that enable customers to transmit voice and data across networks and between systems using different types of media (for example, between copper and fiber). These products assist customers in resolving challenges in the areas of bandwidth constraints, security risks, and distance limitations as networks extend from local area to wide area networks and adapt to ever increasing end-user demands. As enterprise networks continue to change and evolve, our solutions enable customers to both integrate fiber optics into their existing infrastructure as their networks grow, and to extend advanced data services to their customers at remote locations, including supporting wireless networks and backhaul requirements. Many of our products incorporate features to perform advanced levels of fault management and diagnostics to troubleshoot fiber optic and copper network infrastructure. Our growing Power-over-Ethernet (PoE) products support remote devices such as cameras and wireless access points by passing electrical power along with data on Ethernet cabling, eliminating the need for local power in hard-to-reach locations.

Transition Networks products support a wide variety of protocols, including: 10 Gigabit Ethernet, Gigabit Ethernet, Fast Ethernet, Ethernet, T1/E1, T3/E3, DS1/DS3, RS232, RS485, OC3, OC12, among others. Transition Networks develops product hardware and software internally, and expenses the related costs as they are incurred. In connection with the sale of its hardware products, Transition Networks provides its customers with a variety of software management options including Network Management System (NMS) software for providing superior provisioning and monitoring of its Ethernet switches and other managed devices. Transition has been developing and marketing Ethernet-based networking products for over 30 years. Transition Networks continues to develop products that address the enterprise, service provider, industrial, government, and security markets.
