Finisar presents optical communication solutions driving next-gen data centers and carrier networks at ECOC

In booth 62 at the European Conference on Optical Communication (ECOC 2019) in Dublin, Ireland (23-25 September), fiber-optic communications component and subsystem maker Finisar Corp of Sunnyvale, CA, USA is introducing several new product and technology solutions, and demonstrating the latest form factors, laser technology and test equipment for high-speed connections in hyperscale data centers, 5G wireless networks, and optical test systems.

400GBASE-SR4.2 QSFP-DD transceivers for high-speed data centers

Finisar and Foxconn Interconnect Technology are showcasing what is claimed to be the first interoperability demonstration of 400G SR4.2 QSFP-DD optical transceivers. The IEEE-compliant transceivers use eight fibers and an MPO-12 optical connector, which provide a low-total-cost solution for 400G data-rate upgrades using the installed base of multimode cabling deployed for 100G SR4 in data centers today. The IEEE P802.3cm task force has made a baseline proposal for 400GBASE-SR4.2 which includes support for up to 70m on OM3 and 100m on OM4 multimode fiber, aligned with the 400G BiDi MSA. This is the second short-reach 400G multimode transceiver announced by Finisar, following the 400G SR8 OSFP module demonstrated at March’s Optical Fiber Communication conference (OFC 2019) in San Diego.

100G PAM4 VCSEL technology for hyperscale data centers

Finisar is unveiling what is claimed to be the first public technology demonstration of a multimode vertical-cavity surface-emitting laser (VCSEL) transmitting at 100G data rates using PAM4 modulation. This technology demonstration is reckoned to be a milestone towards product developments that can enable 800G short-reach optical modules and active optical cables (AOCs) needed for next-generation hyperscale data centers. Traditionally, multimode transceivers and AOCs that utilize VCSEL technology have offered the lowest cost for short-reach interconnect applications, a trend that is expected to continue with 800G+ products that are based on 100G PAM4 per lane. Attendees can observe the optical performance of the prototype VCSELs over multimode fiber using a high-speed scope.

5G wireless eront-haul Ecosystem featuring tunable SFP28 transceivers

Finisar is showcasing various optical transceiver modules for 5G wireless front-haul networks. Driven by the anticipation of very large-volume deployments, wireless front-haul applications will require cost-efficient high-data-rate solutions. Such applications in 5G networks are expected to require primarily 25G data rates, and Finisar is already offering several products covering 300m, 2km and 10km reaches. For 10km, Finisar provides both duplex and bidirectional transceiver solutions to help customers with optical fiber constraints. For C-RAN applications, Finisar is demonstrating LAN-WDM and O-band CWDM solutions, which enable more efficient wireless front-haul networks with a minimum number of optical fibers.

As part of its 5G product offering, Finisar is also demonstrating full C-band DWDM wavelength-tunable SFP28 modules operating at 25Gb/s over 15km of single-mode fiber. These transceivers are said to provide significant advantages over fixed-wavelength solutions for carriers upgrading their networks to the latest wireless standards. Leveraging DWDM technology allows more efficient use of the limited installed fiber in the front-haul network. Finisar’s wavelength-tunable SFP28 transceivers also provide operational efficiencies and savings over fixed-wavelength products. These products will be available with Finisar’s patented Flextune wavelength self-tuning functionality.

WaveAnalyzer 1500S high-resolution optical spectrum analyzer

The WaveAnalyzer 1500S demonstrates high-speed and high-resolution measurements on optical signals for L-band of telecoms, including OSNR and WDM analysis. This instrument has been designed to support developers of next-generation optical systems. In addition, the WaveAnalyzer 200A portable optical spectrum analyzer will demonstrate spectral measurements in a compact, portable, battery-operated platform. This instrument supports troubleshooting in data-center interconnects as well as mobile measurements in a lab environment.

Finisar IC-TROSA Type-2 demonstration

In booth 441 of the Optical Internetworking Forum (OIF), Finisar is participating in a demonstration highlighting the progress of the OIF’s 400ZR and IC-TROSA (transmitter receiver optical sub-assembly) projects, which aim to reduce the size, cost and power dissipation of 400G coherent optics. Finisar is providing an IC-TROSA Type-2, containing all the optical building blocks for a coherent module in a single miniaturized package. The demonstration highlights important aspects of IC-TROSA integration.
