II-VI demos 400/800G transceivers at OFC
At the Optical Networking and Communication Conference Exhibition (OFC 2021) being held virtually on 6-11 June, engineered materials and optoelectronic component maker II-VI Inc of Saxonburg, PA, USA is giving a demonstration of 400/800G transceivers that can enable next-generation 25.6T and 51.2T data-center switches.
Shown in a video at II-VI’s digital booth, the demonstration is showcasing a broad range of transceiver configurations, reaches and form factors, each supporting the new breakthrough 100Gbps PAM4 electrical interface compatible with next-generation 25.6T and 51.2T switch application-specific integrated circuits (ASICs). The density of these 400/800G transceivers can enable 25.6T in a compact 1RU height.
OFC visitors can view at the II-VI digital booth the following three Finisar transceiver demonstrations:
- 800G-DR8 OSFP and 400G-DR4 QSFP-DD – II-VI is showing an 800G-DR8 OSFP module operating on a link with two 400G-DR4 QSFP-DD modules over parallel single-mode fiber. 800G-DR8 transceivers are also capable of interconnecting with eight 100G transceivers or point-to-point with another 800G transceiver.
- 400G-FR4 QSFP112 and 2x400G-FR4 QSFP-DD800 – II-VI is showing a 2x400G-FR4 QSFP-DD800 module operating on a link with two 400G-FR4 QSFP112 modules.
- 400G-SR4 QSFP112 – II-VI is showing a pair of 400G-SR4 QSFP112 modules operating on a link. Multimode transceivers and active optical circuits (AOCs) that use vertical-cavity surface-emitting laser (VCSEL) technology offer the lowest cost for short-reach optical interconnect applications, a trend that is expected to continue with 800G products. 400G-SR4 transceivers are also capable of interconnecting with four 100G transceivers.
All the demonstrations are showing state-of-the-art optical transmission performance with pre-forward error correction (FEC) bit-error rate (BER) margin against the IEEE specification and post-FEC error-rate performance.
