OIF demonstrates 50 Gbps signals using two modulations

-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.…
