Addressing bandwidth requirements in visual technology
The data capacity crisis is approaching image designers.In established and emerging markets,multiple imaging sources and more advanced sensors output millions of pixels for real-time processing and display.When designers deal with new bandwidth requirements,they must also consider system costs and future scalability.
The imaging industry experienced a series of similar challenges a decade ago,by utilizing established networks and telecommunications standards to provide the GigE Vision standard to address the challenges of cabling,networking,and multicast.In addition,this standard provides imaging system designers with greater authority to reduce costs,as well as widely available and on-site validated components.
To support the next generation of imaging systems,emerging NBASE-T 2.5G and 5G-BASE-T technologies are used as solutions to help designers address bandwidth gaps.
Introduction to NBASE-T Technology
The NBASE-T specification,which is compatible with the recently adopted IEEE 802.3bz standard,has determined a new type of Ethernet signal that can effectively improve the data transmission rate of twisted pair cables,greatly exceeding the previous speed limit of 1Gbps and reaching speeds of 2.5Gbps and 5bps,with a transmission distance of up to 100 meters.This specification supports automatic negotiation systems between the new NBASE-T speed and the lower 1Gbps speed,or,if supported by network infrastructure,this speed can reach 10Gbps
This specification is managed by the NBASE-T Alliance,which is an alliance of over 45 companies covering all major aspects of network infrastructure.The alliance members are focusing on promoting the IEEE 802.3bz standard,encouraging the widespread use and deployment of 2.5G and 5G Ethernet,and promoting the development and collaboration of products with each other.
The initial development of NBASE-T technology was to assist existing campus networks in meeting the new bandwidth requirements brought about by mobile devices,IoT applications,high-resolution video streaming,conference calls,and service quality requirements in multi-user situations.Using a new 802.11ac wireless access node with a total capacity of 5Gbps,help designers find low-cost and effective solutions to connect access nodes and local area networks.
By improving the bandwidth capability of existing Cat5e and Cat 6 cabling,the NBASE-T solution can help users effectively control costs and improve their network speed with minimal change.In addition to meeting the requirements and challenges of wireless local area networks,this technology is also being used to connect clients and desktops to Ethernet switches,network storage devices for wired network infrastructure,and gateways for integrating audio,video,and data services for limited television and telecommunications networks.
NBASE-T and Visual System Design
NBASE-T technology provides a natural way to transition to high-performance imaging systems through its high bandwidth support,low-cost cabling,and compatibility with the G igE Vision standard.
Using the GigE Vision system on NBASE-T and IEEE 802.3bz,designers can transmit uncompressed images at a speed of 5Gbps on Cat 5e copper wire and up to 10Gbps on Cat 6A copper wire.
