Optical Transport

Walker and Associates offers cost-effective, scalable, flexible end-to-end solutions to meet the bandwidth needs for today, as well as the future. Walker’s optical transport solutions cover multiple types of transport services and a broad range of applications that optimize service implementation, minimize complexity in network planning, upgrade existing infrastructures, and create solutions to expand new services to meet demand for transport capacity. Walker’s unique market position as distributor for multiple venders and technologies enables our team of certified specialists to design, build, install and support the optimum network for our clients.

CWDM/DWDM

Wavelength Division Multiplexing (WDM) is a technology that combines several streams of data, storage, video, or voice protocols on the same physical fiber optic cable by using several wavelengths or frequencies of light with each frequency carrying a different type of data. By utilizing Course and Dense (CWDM and DWDM) network systems or the mixture thereof, carriers and enterprises are able to transport services from 2 Mbps up to 100 Gbps of data.

ROADM

Reconfigurable Optical Add-Drop Multiplexers (ROADM) are used in networks to route and switch traffic on and off to optimize capacity and maintain critical 99.999% network up time. Remote reconfiguration capabilities reduce network operating costs, while enabling service providers to add network capacity and manage network resources in real time.

SONET

Synchronous Optical Network (SONET) offers highly secure, cost-effective transport for voice, data, and video traffic. SONET technology uses two or more transmission paths between network nodes, facilitated with digital cross-connects (DCSs) or add/drop multiplexers (ADMs). SONET services scale quickly and easily to handle large amounts of voice and data traffic without compromising reliability. They are designed to allow easy application adoption to your network without disruption.

Packet Optical Networking

As the rapidly evolving transport market moves towards packet-based services such as Ethernet and IP, Packet Optical Networking enables multilayer network convergence, eliminating the cost and complexity of multiple legacy elements, and allowing service providers to leverage their existing network infrastructure.
