Video: Source Photonics Demos PAM4 - 2x50G QSFP28

Pulse Amplitude Modulation encodes information in the amplitude of a series of signal pulses.

In this video, Dr. Manish Mehta, EVP of Product Line Management at Source Photonics, introduces the fundamentals of PAM4 encoding, which is expected to play a major role in enabling lower cost, 100Gbps data center connections.

Source Photonics conducted a live demonstration of PAM4 2x50Gbps QSFP28 transceivers at #OFC2016. These will add to the company's portfolio of small form factor 100G optical transceivers.

The PAM4 demonstration comes on the heels of Source Photonics’ industry leading release of the 100G QSFP28 LR4 platform of products. Source Photonics announced first in industry sampling of the LR4 and LR4 Lite in March 2014 and mass production in March 2015. In January 2016, Source Photonics announced the shipment of its 10,000th QSFP28 module to customers.

The 2x50G-PAM4 QSFP28 will operate at a worst case power consumption of 3.5W at 70C case temperature and support KR4 FEC in the host IC. The company is also in development to support a KP4 FEC implementation similar to the FR8 requirements for 8-channel 400G standards.

“Cloud scale and Web 2.0 datacenters are demanding increased volume and lower cost 100G small form factor products and reducing component count is a critical long term solution”, says Sheng Zhang, Chief Scientist at Source Photonics. “We are demonstrating a major step towards the productization of PAM4 technology that will be instrumental in the cost reduction of 100G QSFP28 products and the release of initial 400G products.”

Cisco Brings High-Density TDM to Optical Transport

Cisco rolled out a number of enhancements to its optical transport portfolio including high-density time-division multiplexing (TDM) to IP/MPLS capabilities.


Some highlights:

Cisco Network Convergence System (NCS) 4200 Series: Part of the Cisco Evolved Programmable Network (EPN), this transport system addresses network inefficiencies with high-density circuit emulation technology located at the network edge. It converts TDM services into pseudowires that facilitate transport over highly scalable MPLS core networks. With this technology, service providers can keep their existing operational models and service revenue while running all services over IP and retiring their older networks. Service providers can reduce space and power required over existing solutions by up to 90 percent.

Multi-service line card for the Cisco NCS 4000 Series - a new, multi-service line card that doubles slot bandwidth to 400Gbps, while providing port-by-port, pay-as-you-grow flexibility for OTN, Packet, MPLS and Coherent DWDM service. When deployed in the Cisco NCS 4009 and NCS 4016 platforms, chassis density doubles to 3.6Tbps and 6.4Tbps, respectively. The NCS 4000 Fabric is also enhanced to help enable unprecedented in-service scale from a single Cisco NCS 4000 chassis (6.4Tbps) to a Multi-Chassis solution capable of delivering over 100Tbps of capacity leveraging Cisco’s multi-chassis leadership.

Increased density and flexibility for the Cisco NCS 2000 Series: New XPonder line card provides 400 Gbps of client and 400 Gbps of trunk capacity to Cisco’s widely deployed optical transport platform. The XPonder supports OTN, packet and coherent DWDM while contributing significantly to cost reduction – one line card for any mix of DWDM, gray, OTN and packet services.

Cisco NCS 1000 data center interconnect solution - commercial shipment is now underway. Cisco said the DWDM solution is now in trials with 9 top cloud providers.

“We are committed to offering service providers the technology to transform their network architectures and achieve the operational efficiency, scale, and reliability needed to succeed in the digital age,” said Bill Gartner, vice president of optical systems, access routing and transceivers group, Cisco. “We are confident that our new innovations in packet optical convergence will enable our customers to transform their networks today while positioning them to face the challenges and leverage the opportunities presented by a future dominated by the Internet of Things.”

Cisco also confirmed that Verizon will deploy the Cisco NCS Series on portions of its 100G metro network.

Semtech Releases Quad 25Gbps Chipset for 100G SR4

Semtech released a new chipset for quad channel 100G-SR4 optical interconnects operating at 25.78 Gbps.

The GN2108 is a quad channel CDR with integrated vertical cavity surface emitting laser (VCSEL) drivers, and the GN2109 is a quad channel CDR with integrated transimpedance amplifiers (TIAs). A full suite of on-chip features minimizes external components and helps customers speed up their hardware and firmware development.

Semtech said its GN2108 VCSEL driver was architected to compensate for optical distortion introduced by VCSELs, enabling extended reach well beyond the SR4 standard to greater than 300m over OM4 fiber, operation with lower bandwidth and lower cost VCSELs, as well as operation with lower VCSEL bias settings for lower power and higher VCSEL reliability.

“The GN2108 and GN2109 chipset has strong traction with our customers,” said Dr. Timothy Vang, Senior Director of Datacom Marketing for Semtech’s Signal Integrity Product Group. “The performance and feature set of the GN2108 and GN2109 is enabling our customers to quickly bring to market winning solutions for 100Gbps QSFP28 and Active Optical Cables (AOCs) for datacenters and a wide range of other applications.”

Molex and Cisco Target Double-Density QSFP Interfaces

Molex and Cisco announced their participation in a multi-supplier agreement (MSA) to create high-speed, double-density quad small form factor pluggable (QSFP-DD), a new high-speed interface. Thirteen industry leaders have joined the MSA to collaborate in developing this new high-speed interface.

The new QSFP-DD interface expands on widely adopted QSFP enabling systems to support backwards compatibility to existing 40 GbE and 100 GbE QSFP interfaces as well as a clear path to future 2x100 GbE and 400 GbE interfaces. By maintaining the same port density per rack unit, customers can speed up networks without redesigning the architecture.

“With a clear trend towards hyper-converged fabrics, customers need an aligned switch silicon and optics roadmap,” said Luca Cafiero, senior vice president and general manager at Cisco. “Global IP traffic is expected to reach 1.4 zettabytes next year, reflecting a CAGR from 2012 to 2017 of 23 percent. All players involved in network architecture will have to step up their game to meet this demand, and the MSA for QSFP DD is a big step in that direction. We are confident that, with industry leaders like Molex, we can help to lead the development of high-speed technology that will be broadly used throughout the industry.”
