OFC: NeoPhotonics’ Nano-ITLA extends ultra-narrow linewidth performance to enable 400G and beyond coherent OSFP and DD-QSFP modules

By Peter Dykes

NeoPhotonics Corporation, which designs and manufactures advanced hybrid photonic integrated circuit-based modules, has announced at OFC the limited availability of its Nano ultra-compact external cavity integrated tunable laser assembly (ITLA). The Nano-ITLA is based on the same high-performance external cavity architecture as NeoPhotonics’ Micro-ITLA product line. Further, the Nano-ITLA maintains comparable ultra-narrow linewidth, low frequency […]

Multimode and singlemode fibres: Comparing 400G access types

400G is now under release over multiple form-factors: QSDFP-DD, OSFP and CFP8. While the short-term deployment is on the access side, and mainly for intra-DC application, other applications such as DCI and transmission are also going on the 400G direction.
