A Revolution in Optical Aggregation Networks Is Coming

Today’s announcement from Infinera, on the industry’s first multipoint coherent transceiver technology, could very well be the next major network inflection point. XR optics technology, leveraging an innovative approach on the use of Nyquist subcarriers, enables a single transceiver to generate multiple, individually routable optical signals. The result is a single high-speed transceiver that can simultaneously communicate with numerous lower-speed transceivers, each with independent, dedicated data streams.

Sterlite’s Stellar Fibre billed as ‘universal fiber’

Sterlite Technologies introduced Stellar Fiber, billed as a ‘universal fiber’ at the India Mobile Congress (IMC) 2019. Stellar Fibre offers ITU-T G.657.A2 bend insensitivity — but with a mode field diameter the size of ITU-T G.652.D fiber, thereby offering bend insensitivity alongside compatibility with legacy fibers. The company claims that Stellar Fibre’s geometry ensures minimal splice loss and promotes proper installation. Simulations at the STL’s Centre of Excellence research facility suggest that use of the fiber can increase a fiber-optic networks lifetime by 10 years or more, thanks to its resilience to cuts and accidental bends.

Stack Infrastructure opens data center campus in New Albany, Ohio

Stack Infrastructure has acquired a purpose built, Tier III data center with 17 acres for future development in New Albany, Ohio. The campus is positioned within the ‘Golden Triangle,’ a geographic area linking Northern Virginia, Northern New Jersey, and Chicago, where the majority of data transmission in the U.S. occurs, resulting in robust fiber-optic and electrical infrastructure.

Single Pair Ethernet Consortium

Cabling Installation & Maintenance interviews Frank Straka, Panduit’s product line manager for copper products, about the Single Pair Ethernet Consortium, discussing the group’s objectives, the single-pair ecosystem, Panduit’s role in the group, and some forthcoming products related to this emerging technology.

Ethernet transceiver sales to decline 18% in 2019

LightCounting expects sales of Ethernet optical transceivers will have declined by 18% when it tallies figures for 2019. The decline is the largest the market research firm has recorded and the first year-on-year dip since 2009, when sales slipped 4%. However, LightCounting states in its new “High Speed Ethernet Optics Report” that purchases of Ethernet optical transceivers should rebound through 2024.

What hampered the deployment of 40G / 100G transceiver in data center? –

This article explores some practical problems and difficulties in the application of high-speed transceiver in the data center. For example, the 40G / 100G high-speed transceiver has not developed a revolutionary new photoelectric conversion technology, but by upgrading the manufacturing process, the original 10G transceiver technology to expand. In essence, for the 10G transceiver, by increasing the number of transceiver fiber to enhance the bandwidth. 

Webinar: TIA-942: The Case for Edge Data Center Certification

TIA-942 standard for data centers is the world’s most popular data center standard. It’s used by well over 70% of the population [of facilities] around the world. Data center stakeholders have been very concerned about ensuring that their data center was designed, built, and approved as having met those criteria. This webinar illustrates the importance and benefits of Edge Data Center certification as a precursor to 5G deployment.
