Diane Bryant, executive vice president and general manager of the Intel Data Center Group, said that initially, silicon photonics components will be used for optical fiber communications between servers and data centers that are located far away.

In a keynote address at the Intel Developer Forum on Wednesday, Bryant said that over time, Intel will deploy fiber optic communications technology at the chip level. This means that the computer's internal data communications will also use optical technology.

Currently, PCs and servers use relatively "stale" wires to transmit data. Bryant said, however, that the speed of data transmission through these cables has reached the limit and that optical fibers can transmit data at a faster rate.

Computerworld said that in an interview, Jason Waxman, vice president and general manager of the Intel Data Center Solutions Group, said that in addition to transmission distance in kilometers, the fiber takes up more space than traditional cables. smaller.

Waxman said that in the data center, optical fiber is better than copper. According to the load and server deployment, fiber costs are also lower than copper cables.

The first batch of silicon photonic module data transmission speed is up to 100Gbps. The fiber optic data transmission technology is based on the widely used Ethernet protocol, but the server will require a dedicated switch that supports the silicon photonics module. The silicon photonics module will eventually support other data transmission and network protocols.

Waxman said that later this year, silicon photonic transceivers and other components will be sold on a large scale.

After years of bouncing, Intel has begun selling silicon photonics modules. Intel has been developing this technology for 16 years, but due to the fact that the product does not meet the quality standards, the time for sale has repeatedly been bounced.

Intel introduced a connector called MXC for fiber optic communications between servers. Intel also developed a protocol called O-PCI (Optical PCI).

According to Computerworld, Intel has ambitious plans for redesigning its data center around silicon photonics. The huge data throughput of optical fiber communications allows major system components, including CPUs, storage systems, and memory, to be separated in separate chassis.

Put storage systems, memory, and CPU into separate chassis to reduce server size and overall power consumption. Decomposing the system into separate chassis is beneficial for in-memory databases and ERP (Enterprise Resource Planning) applications, which require a large amount of memory resources.

Intel tried to use fiber connectors for Thunderbolt, but it was not successful, in part because of the high cost of the fiber. Unlike copper cables, optical fibers cannot transmit power, which means that Thunderbolt peripherals need to have AC power.
