Applied Optoelectronics intros QSFP+ 40-Gbps optical transceivers

Applied Optoelectronics, Inc. (NASDAQ:AAOI; AOI) has unveiled a line of short-reach 40-Gbps optical transceivers in the QSFP+ format for use in data center networks.

The QSFP+SR4 optical transceivers leverage AOI's proprietary silicon photonics-based optical engine technology, including laser and photodiode/pre-amp arrays to support multichannel links. The modules are interoperable with other 40GBase-SR4 QSFP+ and QDR transceivers and support reaches of 300 m over OM3 multimode fiber, AOI says.

To complement the standalone transceivers, AOI also has introduced 40-Gbps active optical cable assemblies (AOCs) for data centers and core network applications. The AOCs come pre-configured with a pair of 40G transceivers or can be delivered with four individual SFP+ 10G serial ports for data centers in transition.

"The need for bandwidth in the datacenter is constantly growing. As a leading provider of Internet data center optics, AOI has spent years developing the suite of technologies desired by our customers, who need interconnection speeds higher than the now-current 10 Gbps rate," says Robinson Tsai, vice president of R&D for AOI's Network Equipment Business Unit. "These technologies currently support 40 Gbps and are extensible to 100 Gbps and beyond. AOI is positioned to work closely with customers to offer a cost-effective solution with industry-leading performance and the ability to customize functions as needed for individual customer requirements."
