Semtech and Coherent demo 200G-per-lane differential driver with 200G DFB-MZ laser
High-performance semiconductor, IoT system and cloud connectivity service provider has Semtech Corp of Camarillo, CA, USA has announced the demonstration of its latest FiberEdge 200G PAM4 MZM driver driving the 200G DFB-MZ laser of materials, networking and laser technology firm Coherent Corp of Saxonburg, PA, USA.
Coherent is conducting a live demonstration of Semtech’s FiberEdge 200G PAM4 Quad MZM driver with Coherent’s 200G DFB-MZ laser in Coherent’s booth #406 at the European Conference on Optical Communication (ECOC 2023) in Glasgow, Scotland, UK (2–4 October).
“We are very excited to continue our collaboration with Coherent as advanced lasers and optics get developed in the 200G-per-lane space,” says Nicola Bramante, senior product line manager for Semtech’s Signal Integrity Products Group. “This demonstration confirms once again the interoperability of state-of-the-art 200G lasers with Semtech’s latest 200G-per-lane FiberEdge developments, ensuring superior linearity and signal integrity in 200G-per-lane Mach–Zehnder modulator-based applications, both in indium phosphide (InP) and silicon photonics. This enables rapid and scalable deployment of next-generation high-performing and reliable switches in data centers,” he adds.
“Coherent continues to demonstrate its leadership in 200G-per-lane laser technology, which is a fundamental building block of 1.6T transceivers with up to 10km reach,” says Coherent’s chief marketing officer Dr Sanjai Parthasarathi.
The joint demonstration at ECOC includes a differentially driven DFB-MZ InP laser from Coherent and Semtech’s PAM4 driver, demonstrating a clear path toward 1.6T and 3.2T optical transceiver deployments in data centers.
