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 […]

WDM – Getting More Out of Your Fibres, a Guide for Musicians

Optical transmission is like light, as you may know it. Light rays from the sun travel massive distances to reach us, and light bulbs perform a similar function but over much shorter distances. To send data down fibre optic cable, we use lasers to make light. We use different wavelengths (or colours) to be able to reach short distances (up to a few hundred metres) or long distances (up to 100s of kms). By switching the laser on and off, we can transfer 1s and 0s (data bits) from one end of a fibre to the other, and very quickly too.
