Coherent showcasing portfolio of new products and technology innovations at OFC
In booth #3412 at the Optical Fiber Communication Conference & Exposition (OFC 2024) in San Diego, CA, USA (26–28 March), materials, networking and laser technology firm Coherent Corp of Saxonburg, PA, USA is showcasing its new products and technologies for next-generation optical communications networks, as well as presenting at panels, technical sessions, and other OFC events.
Recent product announcements
- Significant Advancements in VCSEL Performance
Bandwidth improvement in Coherent’s vertical-cavity surface-emitting laser (VCSEL), paving the way for use in next-generation optical interconnects that will operate at 200Gbps per lane. 200Gbps VCSELs are expected to power future 1.6Tbps transceivers. - 6-inch Indium Phosphide Semiconductor Wafer Fabs
6-inch InP wafer fabrication introduced in both Coherent’s US and European fabs to significantly reduce die cost for InP optoelectronic devices including lasers, detectors and electronics. - I-Temp 100G ZR QSFP28-DCO Module
Industry-first 100G ZR QSFP28 digital coherent optics (DCO) transceiver supporting an industrial operating temperature range; designed for deployment in outdoor environments, this module utilizes Coherent’s Steelerton digital signal processor (DSP), a purpose-built DSP component family launched in 2022, in conjunction with an efficient silicon photonics optical front-end and a power-optimized tunable laser. - High-Power Uncooled Pump Laser Module
New uncooled pump laser modules able to deliver, in a compact 10-pin form factor, up to 1000mW of output power for submarine applications and up to 2x700mW of output power for terrestrial applications. - Bi-Directional Circulator Adaptor
Bi-di circulator adaptor based on Coherent’s vertically integrated circulator technology that enables bi-directional transmission over a single fiber between two transceivers in a compact footprint compatible with all transceiver LC connector ports. - Extended C+L-Band Grism
A family of advanced, aberration-correcting, high-efficiency grisms and transmission gratings capable of encompassing the entire extended C+L band in a single optic. - Microlens Array (MLA) Solution
Comprehensive and versatile platform for advanced collimation, focusing and beam-shaping capabilities in a highly compact package: suitable for high-speed communication transceivers and modules, optical circuit switches, and LiDAR systems.
Technology and product demonstrations
- Optical Circuit Switch for Datacenters
300x300-port Datacenter Lightwave Cross-Connect (DLX), an optical circuit switch based on the company’s field-proven and ultrareliable digital liquid-crystal technology to enable new AI network architectures that replace traditional packet switches with optical circuit switches. - 200G per lane Linear Pluggable Optics for 800G
- Demonstration of linear pluggable optics performance with 200Gbps PAM4 electrical and optical lanes in an 800G-DR4 transceiver platform.
- 800G ZR/OpenZR+ QSFP-DD-DCO
Demonstration of 800G QSFP-DD-DCO in various setups: over an optical link of 450km fiber, in data-center router, and at the OIF booth with 400G and 800G interoperability demo. - 100G ZR QSFP28-DCO I-Temp Module
Demonstration of the industry’s first 100G QSFP28 ZR supporting an industrial operating temperature range (–40°C to 85°C). The coherent transceiver is integrated with in-house purpose-built DSP, silicon photonics optical engine, and tunable laser. - C+L-Band Transport Product Modules
Demonstration of ultrawide-band OCM, C+L-band EDFA, and 3x33 Flexgrid C+L-band twin wavelength-selective switch (WSS) to meet the increasing demand for the expanded transmission bandwidth in DCI, metro and long-haul applications.
Test and measurement
