About the Yamaha OPTOCORE Series
The Yamaha OPTOCORE Series is a family of optical digital network modules built around a synchronous, redundant ring topology. The 1Gbps network transmits up to 512 audio channels at 48 kHz over a single fibre optical cable, and can carry audio, video and control data simultaneously using digital Time Division Multiplex technology with 8B10B-NRZI coding. Static time slots ensure synchronous transmission with no need for dynamic bandwidth allocation or buffers. The Y-Series modules, including the YG2 main card and YS2 sub-cards, are designed for Yamaha devices with Mini-YGDAI slots and connect via standard Cat5 cables. A single YG2 paired with three YS2 cards delivers 64 inputs and 64 outputs, while up to seven YS2 cards can be used per YG2 in 8-channel mode on compatible consoles such as the PM1D.
Yamaha OPTOCORE Series — buyer FAQs
What is the Yamaha OPTOCORE Series and what does it do?
The Yamaha OPTOCORE Series is a family of optical digital network modules that form a synchronous, redundant ring network capable of transporting audio, video, control data and word clock over long distances. The network operates at 1Gbps and uses digital Time Division Multiplex technology with static time slots, ensuring synchronous transmission of all channels at any time without dynamic bandwidth allocation or buffers.
How many audio channels can the Yamaha OPTOCORE network carry?
The 1Gbps network supports up to 512 audio channels at a sample rate of 48 kHz over a single fibre optical cable. When audio, video and data are transmitted simultaneously, those signal types share the available bandwidth, since audio and video are treated as continuous signals within the TDM architecture.
What are the YG2 and YS2 cards, and how do they work together?
The YG2 is the main card containing the core Optocore interface, designed for Yamaha devices with Mini-YGDAI slots and enabling direct connection to the Optocore optical digital network. The YS2 is a sub-card that connects to it via standard Cat5 cable. One YG2 paired with three YS2 cards delivers 64 inputs and 64 outputs, and up to seven YS2 cards can be connected to a single YG2 when 8-channel mode is enabled on compatible consoles such as the PM1D.
Who makes the OPTOCORE Series and where does it fit in the Yamaha range?
The OPTOCORE Series is made by Yamaha, a Japanese corporation whose Pro Audio division produces professional equipment for live sound and installation, including mixing consoles, signal processors and speakers for touring, broadcast and venue use. The OPTOCORE modules sit within the signal networking layer of Yamaha's professional offering, extending digital console installations by connecting Yamaha devices via an optical ring network.
What should I check when buying a used Yamaha OPTOCORE Series module?
Check which specific module is included, whether it is a YG2 main card, YS2 sub-card or another unit in the series, and confirm how many cards are in the package, since channel capacity depends on the combination. Verify the condition of the fibre and Cat5 connectors.
