电脑迎来光接口时代

台系主板厂商，尤其是Asus和Asrock，都开始在主板上支持Thunderbolt，Asus甚至有PCIe-Thunderbolt的转接卡，难道让用户买回去接苹果的显示器吗，哈哈。不过他们推的都是电版本的，不像骚尼直接支持光。

Ensphere Solutions Inc., a fabless semiconductor company headquartered in Santa Clara, CA, says the first Thunderbolt active optical cables (AOC) to enter the market are based on its ESI-XVR10100 optical transceiver.

Thunderbolt is a high-speed PC connection technology developed by Intel Corp., initially under the name LightPeak. It provides bi-directional 10-Gbps data transmission, and is PCI Express and DisplayPort compatible. Sumitomo started shipping Thunderbolt cables back in April (see "Sumitomo Electric samples optical Thunderbolt cable").

Ensphere says the ESI-XVR10100 optical transceiver device is ideally suited for optical Thunderbolt cable designs. The device offers two 10-Gbps lanes, on-chip thermal sensors and VCSEL compensation logic to ensure the best overall performance. OEM customers can pre-program special operating characteristics into its OTP memory, and can add up to four slave devices for applications requiring wider parallel interfaces.

"Optical cable suppliers know the importance of choosing high performance 10-Gbps optical engines with a careful balance of silicon CMOS performance, low power operation, and low-profile products in order to meet the overall optical Thunderbolt design requirements," said Hessam Mohajeri, founder and CEO of Ensphere. "That the first such cables to enter the market have chosen the Ensphere ESI-XVR10100 is an acknowledgement of our design and delivery capabilities."
