Lantronix CWDM-A2A8xxLCR-B Series Fiber Connectivity for Advanced Traffic Mana - Page 2

Case Study signals on county roads. As traffic camera resolutions improve and collect more data, higher-bandwidth networks are essential to handle additional data load and the distance from the light signal to the control center. A fiber-optic network would allow for each traffic signal to communicate and transmit real-time traffic conditions to local operations centers to enable improved signal timing and better overall traffic flow. However, purchasing and installing fiber optic cabling is expensive. Fiber must be crimped and requires costly and time-consuming underground trenching to lay the cabling. Minimizing the amount of new fiber needed for the network was critical to keep the project under budget. The Solution The county decided to capitalize on its existing fiber infrastructure by selecting Lantronix Coarse Wavelength Division Multiplexing (CWDM) Mux/Demux, Add/Drop Mux devices and CWDM SFPs to enable its fiber-optic connectivity. CWDM is a wavelength division multiplexing (WDM) technology that transmits multiple optical signals onto a single fiber pair by using different wavelengths of light. It can send data via unique wavelengths for simultaneous transmission over fiber pair cables. CWDM is a cost-effective method to capitalize on existing fiber cabling because it uses the nanometer channel spacing between wavelengths, allowing more data to be transmitted. Lantronix's CWDM Mux/Demux and Add/Drop Mux optical devices allow for expanded capacity using existing fiber infrastructure and provides the scalability to grow fiber capacity with little or no increased cost. The devices can transmit high speeds and multiple protocols over an existing duplex fiber with no configuration or utility power necessary. Lantronix Solutions Lantronix CWDM SFP transceivers offer a cost-effective and flexible means to accommodate network modifications for growth and provide 1G to 10G speeds. The SFPs are Multi-Sourcing Agreement (MSA) compliant, ensuring interoperability with all other MSA-compliant networking devices. The CWDM modules are available as 4-channel, 8-channel, or 16-channel mux/demux modules, supporting an optional add/drop capability and a scalable bandwidth of up to 10 Gbps per channel over existing fiber links. The modules are plug-and-play, requiring no configuration of CWDM components, and can use existing standard optical ports on switches and routers. The modules support a wide temperature range (-20 to 70◦C). transition.com | +1.952.941.7600 081121 2
