The 100G QSFP28 to 4x 25G bi-directional AOC has been issued a U.S. provisional patent.
Englewood Cliffs, NJ, May 30, 2023 — Vitex LLC, a New Jersey-based supplier of specialized, superior quality fiber optic and connectivity products, announced that their new-to-market and award-winning 100G to 4x 25G bi-directional AOC (active optical cable) has been granted a United States Patent and Trademark Office (USPTO) “provisional patent”.
The pending patent–entitled “Multichannel Fiber Optic Transceiver”– describes in detail the design of a device that plugs into a single high-speed transceiver port on a communication switch or other device and creates multiple, simultaneous bi-directional fiber optic connections to lower-speed fiber optic transceivers located in other switches or devices.
The essence of the invention is a bi-directional AOC that allows a 100G port to break out to 4x 25G LC connections, where each 25G connection is a single fiber. The QSFP28 device contains 4 optical engines, each of which is a 25G-BiDi transmitting at 1270 nm and receiving at 1330 nm. The interface to fiber fronthaul infrastructure is provided with 4x single-fiber pigtails.
Vitex’s new 100G BiDi AOC device is designed for 5G telecom networks to:
- double existing fronthaul fiber capacity
- provide 25G bi-directional connectivity over a single fiber
- deploy 25G BiDis to denser 100G routers
- be interoperable with off-the-shelf SFP28 transceivers
“As a specialized developer and supplier of fiber optic connectors for twenty years, I was thrilled when the Vitex 100G BiDi breakout AOC was recognized as unique with a prestigious Lightwave award. The excitement has only multiplied with our very first patent-pending notification,” says Michael Ko, Managing Director at Vitex. “Our mission and interest is solving communication problems. In this particular situation, the 100G QSFP28 to 4x 25G parallel bi-directional AOC was developed for the 5G telecommunications market as a singular solution for condensing 4x 25G installations into a single 100G QSFP socket. The product’s success is lockstep with our commitment to solving engineering problems with creativity and innovation.”
