Sumitomo Electric Receives the World’s First Thunderbolt Certification for the Optical Thunderbolt Cable, and Starts Mass Production

Sumitomo Electric Industries, Ltd. (TOKYO:5802)(ISIN:JP3407400005) has become the first company to receive Thunderbolt certification from Intel Corporation for the optical Thunderbolt cable and has started the mass production. Based on Intel’s Thunderbolt technology, this new optical Thunderbolt cable enables long-distance data transmission. Sumitomo Electric developed this cable through its expertise in optical fiber and module development and, in April 2012, began shipment of the sample products.

All Thunderbolt products must undergo a certification process to ensure optimal operation and end-user experience. The officially certified products provide highly reliable data transmission at a high speed of 10Gbps.

“Thunderbolt technology continues to bring performance and versatility to Macs and PCs today,” said Jason Ziller, Director, Thunderbolt Planning and Marketing, Intel Corporation. “Sumitomo’s new optical Thunderbolt cables add another level of versatility to Thunderbolt, especially for media creators and enthusiasts.”

The optical Thunderbolt cable is an active optical cable that enables long-distance transmission up to 30 meters to connect Thunderbolt devices together. The optical Thunderbolt cable is the same diameter as the conventional metal Thunderbolt cable (4.2 mm), and handles just as easily. Sumitomo Electric’s special optical fiber makes the cable robust and durable for everyday use. This optical fiber offers high bending performance even when pinched up to 180 degrees or tangled in knots.

DXWorldEXPO LLC announced today that Telecom Reseller has been named "Media Sponsor" of CloudEXPO | DXWorldEXPO 2018 New York, which will take place on November 11-13, 2018 in New York City, NY. Telecom Reseller reports on Unified Communications, UCaaS, BPaaS for enterprise and SMBs. They report extensively on both customer premises based solutions such as IP-PBX as well as cloud based and hosted platforms.
Enterprises are striving to become digital businesses for differentiated innovation and customer-centricity. Traditionally, they focused on digitizing processes and paper workflow. To be a disruptor and compete against new players, they need to gain insight into business data and innovate at scale. Cloud and cognitive technologies can help them leverage hidden data in SAP/ERP systems to fuel their businesses to accelerate digital transformation success.
The deluge of IoT sensor data collected from connected devices and the powerful AI required to make that data actionable are giving rise to a hybrid ecosystem in which cloud, on-prem and edge processes become interweaved. Attendees will learn how emerging composable infrastructure solutions deliver the adaptive architecture needed to manage this new data reality. Machine learning algorithms can better anticipate data storms and automate resources to support surges, including fully scalable GPU-centric compute for the most data-intensive applications. Hyperconverged systems already in place can be revitalized with vendor-agnostic, PCIe-deployed, disaggregated approach to composable, maximizing the value of previous investments.
