TIA’s TR-42.7 Engineering Committee on Telecommunications Copper Cabling Systems (568) has issued a call for interest for document ANSI/TIA-568.6, initially titled, “Single Pair Multi-Drop (SPMD) cabling and component specifications.” The standard will address the need to support applications that use a bus topology with multiple branches connecting communication devices.
“If you go proprietary rather than standards-based, you’ll rue the day,” says Glenn Sexton. “When we build to standards, we know interoperability is not going to be an issue. We have school-system clients where cable we spec’d in the mid-1990s is still delivering 100Base-T to workstations, to this day.”
In a perfect world, all network devices would be located within the standard 100-meter run length, But design and budget constraints don’t always allow for that, and there are instances when data transmission does need to exceed 100 meters. Lately, there has been quite a bit of attention surrounding cable products that claim to support data and Power over Ethernet (PoE) to distances far beyond the standard length. Do they merit the attention, and do they represent good network design practices?
The standardization that 5G brings is good for interoperability, but if implemented poorly, presents a greater cyber risk to future cities. 5G will replace not just legacy cellular standards, but a multitude of other wireless and wired communication standards and therefore its scope will cover personal use, business operations, transportation and smart city infrastructure. This, together with its support for dense IoT networks – which could potentially have over 1 million devices per square kilometre – means an exponential increase in the attack surface and exposure to cyber attacks on an unprecedented scale.
It’s challenging to make the right decision on passive infrastructure deployment in the presence of incomplete information on future transmission technologies and future network architectures. One tactic to deploy hybrid cables to account for potential disruptions that next-generation transmission technologies may bring. A hybrid optical fiber cable is one that features two or more different fiber types within the same physical construction to provide greater flexibility for the network operator.
TIA TR-42.11 Engineering Committee on Optical Fiber Systems (568) has issued a call for interest on two documents: ANSI/TIA-568.3-E and TIA-526.14-D. The revision to TIA-568.3-D will include General Updates and any additional content deemed appropriate by formulating subcommittee. For TIA-526.14-D, the committee will develop guidelines for Optical Power Loss Measurement of Installed Multimode Fiber Cable Plant and add reference to bend insensitive MM fiber for testing with EF compliant launch cord.

The standards development efforts that will produce specifications for single-pair data transmission and single-pair cabling systems will build on a vehicular-related foundation. In 2015 the IEEE completed its 802.3bw standard which specifies 100Base-T1 systems, driven by the automotive industry’s needs.
For edge data centers to live up to their potential, a number of specific requirements need to be taken into consideration, directly impacting the design, size, costs and location. Standards bodies like TIA are defining the differences between traditional data centers and edge data centers and developing the standards that address availability, power, cooling, physical security, and critical cabling systems.
The growing popularity of 400-Gbps transmission rates will lead DWDM coherent port shipments to reach 1.3 million by 2024, according to Dell’Oro Group. The market research firm states in its latest report that the total optical transport market, which Dell’Oro defines as including multiservice multiplexers and WDM systems, will be worth nearly $18 billion by that year.
