Finisar Unveils New Solutions for Optical Networks

Leading optical transceiver and component solution provider, Finisar has unveiled a series of new product solutions for technology demonstrations during the Optical Networking and Communication Conference  & Exhibition (OFC) being held in San Diego, the USA. Finisarisshowcasing optical module solutions for hyperscale data centers, 5G wireless networks, and data center interconnects.

The live demonstrations will include the latest form factors that will drive the next generation of optical networks. The New product solutions include, 2x200G and 400G FR4 Optical Modules for data centers, 400G DR4 QSFP-DD Modules, 400G SR8 OSFP Modules, 25G Direct Detect Tunable Bidi SFP28 for 5G networks, 25G LR Lite SFP28 Optical Transceivers, and 64G Baud Integrated Coherent Transmit & Receive Optical Sub-Assembly.

Finisar will Demonstrate the following;

A suite of 200G, 2x200G, and 400G FR4 modules for high-speed data centers
A 200G FR4 module in a QSFP56 form factor, a 2x200G FR4 in an OSFP form factor, and a 400G FR4 in a QSFP-DD form factor, each running over single mode fiber.

400G DR4 QSFP-DD modules in break-out and shuffle configurations
400G DR4 QSFP-DD module in both break-out and shuffle configurations, allowing maximum deployment flexibility. In the break-out configuration, two 400G DR4 modules receiving data streams from an Ixia AresONE QSFP-DD test system, transmit four independent 100G PAM4 lanes to four separate Finisar 100G FR QSFP28 modules. In the shuffle configuration, 100G PAM4 lanes from a 400G DR4 module connect to another 400G DR4 module via shuffled lane assignments. The 400G DR4 transceiver module, compliant to the IEEE802.3bs standard, is critical not only to support the continuing growth in network bandwidth but also to provide the flexibility needed by large scale data center customers that require 100G granularity in their architectures.

400G SR8 OSFP modules for multimode applications
400G transceiver modules designed for short reach, multimode applications. Multimode fiber has long been a staple of data center infrastructure, especially in the enterprise and small cloud markets. This demonstration will showcase IEEE-compliant 400G SR8 optical modules in the OSFP form factor, running over 100 meters of standard OM4 multimode fiber. The modules use a 16-fiber, MPO-16 optical connector and can be deployed as point-to-point or in a break-out configuration of its 50G PAM4 lanes. They leverage VCSEL technology in the 850nm band to achieve the lowest power dissipation and lowest cost structure.

Finisar has actively participated in the definition of the QSFP-DD (Quad Small Form Factor Pluggable Interface Double Density) and OSFP (Octal Small Form Factor Pluggable) MSA modules, which are the latest form factors targeting 400G data rates. Both designs provide an eight-lane electrical interface, compared to traditional single or four-lane interfaces, thereby increasing bandwidth, channel capacity, and port density. These form factors address the need for high-density, high-speed networking solutions.

25G Direct Detect Tunable Bidi SFP28 technology for 5G wireless networks
Next generation 25G tunable Bidi technology in an SFP28 form factor. This technology is the key building block for deploying these transceivers and will enable cost-effective next-generation 5G wireless build-outs while also providing significantly more data capacity per fiber than other 25G-based optical architectures. The Bidi technology will also incorporate innovative and unique Finisar transceiver features, such as T2DOC™ and Flextune™. These features enable Transceiver-to-Transceiver communications and self-wavelength tuning of remote modules during commissioning without host interaction. Both T2DOC™ and Flextune™ simplify field installation and remote maintenance while lowering operational expenses.

25G LR Lite SFP28 transceiver for 5G Mobile networks
A new, cost-optimized 25G SFP28 module for front-haul applications in 5G wireless networks, which uses a Fabry-Perot (FP) laser. Most single-mode 25G optical modules rely on more costly Distributed Feedback (DFB) lasers to reach the 10km distances set by the IEEE standard. Finisar’s demonstration will show how low-cost FP lasers running at 25G data rates can support not only the 300 meters of reach required by the majority of 5G front-haul deployments but also exceptional cases of 1km spans. The company has been a strong supplier of optical modules for 3G and 4G mobile infrastructure, and it is now rolling out its portfolio for 5G.

64Gbaud Integrated Coherent Transmit & Receive Optical Sub-Assembly
Integrated Coherent Transmit & Receive Optical Sub-Assembly, designed to the current draft of the OIF IC-TROSA Type-2 requirements. The IC-TROSA Type-2 is an optical sub-assembly combining all key building blocks of a coherent optical front-end (i.e. tunable laser, optical amplifier, modulators, drivers, coherent mixer, photodiode array, and TIAs) – with internal control electronics. The device is Flexgrid® C-band tunable and supports multiple modulation formats, including QPSK, 8QAM, and 16QAM, at symbol rates up to 64Gbaud, enabling data transmission up to 400 Gb/s. The IC-TROSA’s low power dissipation and miniature footprint enables small form factor Digital Coherent Optics (DCO) transceivers in a QSFP-DD or OSFP form factor, as well as very high-density coherent line card or daughtercard designs.
