Webinar: Single Pair Ethernet Standards Update, Use Cases and Applications

Single Pair Ethernet is poised to enable a new class of low power devices that will facilitate networking and powering the billions of endpoint sensors forecasted by the year 2022. The SPE standards provide endpoint sensors with a unifying communication protocol and a common networking infrastructure extending the cost-effectiveness and plug-and-play simplicity of Ethernet. Endpoint sensor technology and use cases are evolving rapidly in industrial/process, building automation, data centers as well as to support “Intelligent Building” technologies; IoT infrastructure. TIA’s TR-42 committee is developing single pair telecommunication standards for single pair infrastructure topologies, cabling, and field testing.

Webinar: VIAVI Solutions YouTube LIVE Ethernet Basics

VIAVI Solutions is hosting a live Ethernet Basics session presented by System Engineers, Dave Baker and Peter Desmarais. Attendees will learn Ethernet technology basics including line rates (10M to 400G), types of pluggable optics, link establishment processes, frame structures, key performance indicators, and best practices to test connectivity and service activation. The presentation will include tips and tricks for novices as well as experts.

What’s an MPO connector?

Multi-fiber push on connectors (MPO) are a single connector that houses multiple fiber terminations, defined by IED=61754-7.14. The MPO’s rise in popularity is due to it’s ability to mate multiple fibers (2-72) within a single connector body, thereby significantly reducing the space needed.

When to use OM4+ optical fiber over OM5 optical fiber

Since the TIA ratified the specification for OM5, a wideband multimode optical fiber (WB-MMF), customers that are thinking about upgrading their existing infrastructure, or building out new, are asking a question: Should they deploy OM5 fiber? OM5 is essentially an OM4 fiber that has an additional bandwidth specification at 953nm. Both OM4 and OM5 have bandwidths specified as 4,700MHz•km at 850nm, and OM5 has a bandwidth specification of 2,450MHz•km at 953nm. OM4 does not have a bandwidth specified at 953nm. OM5 was designed to be used with optical modules that employ Shortwave Wavelength Division Multiplexing (SWDM). These new SWDM modules use four wavelengths that span from 850nm through 953nm, to implement 100Gbps links.

Industrial Ethernet testing guide available for download

A free testing guide for industrial systems integrators is available from Fluke Networks and Rockwell Automation. The guide provides a comprehensive approach to reduce startup and operational problems related to copper and fiber-optic cabling and allows integrators to deliver more-reliable customer solutions.Testing cabling during the start up process helps avoid many industrial Ethernet failures.

SINGLE-MODE Fiber Continues to Gain Momentum

Over the past several years, Leviton has polled network professionals about the type of fiber they would install today, and we have seen solid growth in single-mode. In the March 2020 poll of 281 network professionals, more than 60% said they would install single-mode (OS2) today over multimode types, with OM4 coming in second at 28%. This change is largely a result of decreasing cost and recent standards committee activities that continue to promote more single-mode options for higher speeds such as 200 and 400 Gb/s. As this trend continues, the market in general will find single-mode a more enticing option. Let’s take a closer look at reasons behind its rise.
