Finisar Corporation introduced several new products to be demonstrated at OFC, the optical networking and communication conference and exhibition. The products include 400G QSFP-DD LR8 and FR8 transceivers, a 400G QSFP-DD active optical cable, a 100G serial QSFP28 transceiver, and two 50G SFP56 transceivers supporting a variety of next generation of Ethernet applications. These new form factors and data rates represent the latest advances in networking technology, geared toward the next generation of optics that will operate at 50 and 100 Gb/s per lane. The 50G and 100G lanes use PAM4 encoding instead of the traditional non-return-to-zero (NRZ) format, and are crucial to enable hyperscale data centers, service providers and enterprises to meet tomorrow's voracious bandwidth demands. The QSFP-DD (Quad Small Form Factor Pluggable Interface Double Density) is the latest module form factor targeting 400G data rates. The design provides an eight-lane electrical interface, compared to traditional single or four-lane interfaces, thereby increasing bandwidth, channel capacity and port density. Defined by the QSFP-DD MSA Group, this module addresses the need for high-density, high-speed networking solutions in a backward compatible form factor. 400G QSFP-DD LR8 and FR8 TransceiversFinisar is unveiling the industry's first demonstration of a 400G QSFP-DD LR8 transceiver, whose 10km reach is a critical requirement for service provider applications. Using 50G PAM4 technology, the demonstration will show an optical module transmitting data over 10km of duplex single mode fiber (SMF). In addition to the 10km LR8 module being demonstrated, a 2km FR8 variant of this module will also be available from Finisar, primarily for intra-data center applications. Both the LR8 and FR8 modules leverage DML transmitter technology, providing a low power, low risk, cost- effective solution for 400G. 400G QSFP-DD Active Optical CableFinisar is extending its leadership in the market with the addition of the industry's first 400G active optical cable (AOC) in the QSFP-DD form factor. Leveraging VCSEL technology to achieve the lowest power dissipation and lowest cost structure, this product provides a desirable alternative to copper cables, which cannot scale to the required cable lengths at these high data rates. In a joint collaboration, Finisar is demonstrating the 400G QSFP-DD AOC running traffic through a Cisco demonstration switch.
