OpenLight unveils 224G InP-based modulator

Tuesday, March 07, 2023

OpenLight demonstrated a 224G InP-based modulator available for Tower's PH18DA platform for datacom applications supporting 224G per wavelength

The new 224G modulator is integrated on a demonstration PIC with a heterogeneous integrated laser and other required silicon photonics components to enable a full transmitter.

"This new modulator doubles the speed of every PIC," said Dr. Adam Carter, Chief Executive Officer at OpenLight. "For instance, our 800G DR8 PIC which was recently announced can become a 1.6T PIC (8x200G). Alternatively, a 400G DR4 PIC can now deliver 800G with four lanes. Our latest offering allows datacom customers to not only prepare for the future, but also keep up with the growing need for increased connectivity speeds."

"Our partnership with OpenLight continues to augment capability offered to all our silicon photonics foundry customers," said Dr. Marco Racanelli, Senior Vice President and General Manager of Tower Semiconductor's Analog Business Unit. "OpenLight's technology through Tower Semiconductor allows customers to achieve 224G operation on a silicon photonics platform and achieve the same benefits offered by on-chip lasers and optical gain without the need for separate lasers and costly attachment methods."

"200G modulation is a key building block and critical path to the delivery of next generation Ethernet speeds based upon 200G/lane," said Jim Theodoras, Vice President of Research and Development at HGGenuine USA. "This is not just a 200G modulator, but one that is available in a hybrid photonic integrated circuit. Next generation Ethernet cannot be delivered at the power and densities being requested by datacom customers without photonic integrated circuits, and we are happy to partner with OpenLight on their industry leading PIC technology that will enable not just 1.6T today, but also 3.2T in the near future."

Open XR Forum completes test of Point-to-Point 400G Pluggable Optics

Tuesday, March 07, 2023

The Open XR Forum demonstrated long-haul point-to-point transmission between QSFP56-DD coherent transceivers over 1,400 km at 400 Gb/s using 16QAM modulation, as well as error-free performance at 300 Gb/s using 8QAM modulation over a span of 2,495 km.

The testing was conducted in conjunction with founding member Lumen Technologies using Infinera's ICE-XR 400G QSFP56-DD transceivers operating in third-party routers and transmitting over third-party line systems. The long-distance performance demonstrates the potential for pluggable transceivers to be used in DWDM long-haul and large metro networks. The integrated management features, which included in-band remote management and streaming telemetry, demonstrated transport functionality typically found in a transponder, but in the compact form of a pluggable transceiver. This management decoupling of key transceiver functions from host routing functions is a new and easily generalized method for integration and management of coherent transceivers in any host device, including routers, switches, and servers. The ability to separate management of IP and Optical functions better aligns with existing service provider operational models, helping resolve a key barrier for deployment of IP over DWDM.

The Open XR Forum said the demonstration is significant in two ways:

long-reach performance equal to or greater than current state-of-the-art transceivers,
the first published demonstration of an advanced management method that enables management and control of optical transceiver functions independently from the host equipment.

The details and results of this demonstration are available in an Open XR Forum report, P2P (Point-to-Point) Performance and Host Independent Management Proof of Concept Demonstration.

QSFP-DD MSA to extend module bandwidth to 1.6 Tbps

Sunday, March 05, 2023

The QSFP-DD Multi Source Agreement (MSA) plans to develop a new specification extending the bandwidth of the form factor to 1.6 Tbps. The new specification will leverage 200 Gbps serial PAM4 SerDes technology currently under development.

The new specification will maintain the form factor’s eight lanes to provide an aggregate bandwidth capacity of 1.6 Tbps. The 1.6 Tbps module port will maintain backward compatibility with the entire family of QSFP and QSFP-DD modules and cables. This will provide the high degree of flexibility that end users and system designers have come to expect from QSFP and QSFP-DD, easing end user’s migration to the industry’s speed transitions. The new specification will also maintain the QSFP-DD’s riding heatsink feature that enables system designers the ability to efficiently cool higher power modules that may be required in next generation equipment.

The new QSFP-DD1600 specification will target the current port density enjoyed by systems utilizing QSFP-DD today and meet the faceplate bandwidth that is expected from next generation ASICs in the future.

“QSFP-DD’s backwards compatibility has been critical to our operational approach to upgrading the network,” says Jamie Gaudette, Partner Network Engineering Manager, from Microsoft, “We encourage the MSA’s work on QSFP-DD1600.”

“The system design flexibility that QSFP-DD enables greatly reduces the challenges in building systems with high-power modules,” says Mark Nowell, MSA co-chair, “the riding heatsink, besides enabling backwards compatibility, is an asset to system designers.”
