SENKO receives VSFF fiber connector patent, with more on the way

April 21, 2022
SENKO says it has received more than 45 issued patents on Very Small Form Factor (VSFF) technology and has more than 65 additional applications pending.

Senko Advanced Components, Inc. says it has received U.S. Patent No. 11,280,972 from the U.S. Patent and Trademark Office for innovations related to Very Small Form Factor (VSFF) interconnect. The patent covers an LC ferrule connector that accommodates eight fibers in a QSFP transceiver footprint. SENKO says it has received more than 45 issued patents on VSFF technology and has more than 65 additional applications pending.

The VSFF patents cover technology used in such advanced fiber connectors as the SN connector (including 11,169,338) and CS connector (including 11,287,583) as well as corresponding adapters (including 11,187,857 and 11,152,748). Senko says its MT ferrule VSFF connector earned its own allowed US Publication No. 2021/0271030.

Upcoming VSFF connector technology patents SENKO expects to receive one for remote release technology (11,307,369) for VSFF connectors. SENKO adds it also has developed advanced polarity change features for VSFF connectors (including 10,191,230 and 10,705,300).

“The issued patents and the soon-to-be-issued patents demonstrate our commitment to developing the VSFF interconnect family, where the CS is currently a TIA standard (TIA-604-19) and the SN is undergoing standardization at IEC (IEC 61754-36). As of the beginning of 2022, SENKO has shipped well over 1 million VSFF connectors and we are pleased that these new innovations are well received globally,” commented Kazu Takano, president of Senko Advanced Components, a wholly owned subsidiary of SENKO Advance.

“Currently we are honored to have more than 60 companies who have adopted the CS and SN technology including 30-plus licensees and look forward to welcoming additional companies,” Takano continued. “We are very pleased with these recent accomplishments as it shows to the industry SENKO’s commitment to be a pioneer and leader in the development of fiber interconnect products”
