OIF Unveils OFC Interoperability Demo Plans

The Optical Internetworking Forum (OIF) today released the slate of public demonstrations that it will conduct at OFC in Anaheim, March 22-24, 2016. The demo will showcase multi-vendor interoperability of two key technologies; Pluggable Coherent Optics and 56G Electrical Interfaces.  These technologies will cover a range of channel reaches from Very Short Reach (VSR) to Long Reach (LR) and includes using both NRZ and PAM4 modulation formats. Live CFP2-ACO pluggable coherent optics, based on the recently announced OIF implementation agreement, and attendant test equipment are also part of the display. The demonstrations will be conducted in the OIF Booth #3619. In addition to the live demonstration, OIF industry experts will conduct two panel discussions at OFC on Tuesday, March 22.

“The OIF will be extremely busy at OFC this year,” said Steve Sekel of Keysight Technologies and the OIF Physical & Link Layer Interoperability Working Group Chair. “This is a very ambitious interoperability demo and we have a large slate of thought leaders speaking during the conference. In addition, the OIF’s industry leadership at OFC will conduct a public workshop on 100G Serial Electrical Links.”

The technologies on display during the live interoperability demonstration include CFP2-ACO Optical Modules, Coherent DSPs and Compliance Boards.  Also included will be CEI-56G silicon for PAM4 and NRZ demonstrated in VSR NRZ and PAM4 channels, medium reach NRZ and PAM4 cable channels and a long reach PAM4 backplane channel. Participating companies include Amphenol, Anritsu, ClariPhy, Credo, Fujitsu Optical Components, Inphi, Keysight Technologies, Molex, MultiLane, TE Connectivity, Tektronix and Yamaichi Electronics.

OIF Workshop on 100G Serial Electrical Links

The OIF will host a public workshop addressing the latest developments in 100G Serial, immediately following OFC 2016 in Anaheim, California. The event, OIF Workshop – 100G Serial Electrical Links and Beyond, is open to the public and scheduled for Thursday, March 24, 2016, from 12:30 pm to 6:15 pm at the Anaheim Marriott Hotel. The workshop will feature subject matter experts from the OIF and will include an industry view presented by Dale Murray, Principal Analyst at LightCounting Market Research.

Registration fee includes a one-hour cocktail reception. For details including registration information, please click HERE.

OIF PLL Interoperability Demo 2016

OIF member companies will demonstrate multi-vendor interoperability of Pluggable Coherent Optics and 56G Electrical Interfaces in live, operating environments. The OIF’s Physical and Link Layer Working Group demonstrations include live 56G electrical interface interoperability over a range of channel reaches from VSR to LR and a range of modulations including NRZ and PAM4. The expanding ecosystem will be showcased through live demos. 56G and coherent optics test equipment will also be demonstrated. Public demonstrations will be on display March 22-24, 2016 at OFC in Anaheim, CA in OIF Booth #3619. Additional information can be found at

OIF demonstrates 50 Gbps signals using two modulations

Martin Rowe -March 30, 2015

Last week at OFC 2015, the OIF (Optical Internetworking Forum) demonstrated two 50 Gbps transmissions using both PAM4 and NRZ formats. Over the past year, PAM4 has emerged as what appears to be the modulation format of choice for many systems, although NRZ will still have its place.

PAM4, the topic of the Jitter Panel at DesignCon 2015, looks to become the modulation format for LR (long reach) and MR (medium reach) optical links. In particular, PAM4 looks to take over from NRZ for electrical links that lead up to an optical module and across backplanes. For XSR (extra-short reach) applications, NRZ is likely to live on in applications where signal-to-noise ratio is important such as within an optical module or in memory buses. The two videos below show demonstrations from the OIF booth.

In the first video, Scott Sommers of Molex shows a 50 Gbps PAM4 signal traveling over a 0.54 m Molex backplane. The signal is generated by an (AWG) arbitrary waveform generator from Keysight Technologies. The demo uses the AWG because silicon to generate the PAM4 signal isn’t yet available.

Silicon that can generate a 56 Gbps data stream using NRZ is available, and Jeff Twombly of Credo Semiconductor demonstrated it in the OIF booth. In this demonstration, a Credo 56G NRZ SerDes drove three demonstrations: a CEI-56G-VSR-NRZ channel, a CEI-56G-MR/LR-NRZ backplane and a CEI-56G-MR-NRZ passive copper cable. The video shows the signal passing through a 1 m length of copper cable.
