Abstract

The invention provides a gigabit double-optical-port server adapter. The adapter comprises a first PHY layer controller, a second PHY layer controller, an MAC layer controller, a PCIE interface and two gigabit optical fiber ports. The MAC layer controller comprises a bus interface, a receiving cache module, a sending cache module, a flow control module, a receiving module, a first sending module,a second sending module, a first PHY interface, a second PHY interface and a link fault judgment module. The adapter supports a computer end interface. A main port and a standby port are provided. Oneport is a working port, and the other port is a standby port. When the working port breaks down, the standby port can be replaced to continue working, when one link breaks down, the connection stateof the network is guaranteed by switching to the other link, non-inductive switching is achieved, transmission delay is reduced, and transmission efficiency is improved.

Description

Technical field [0001] The invention belongs to the technical field of adapters, and particularly relates to a gigabit dual optical port server adapter. Background technique [0002] With the advancement of technology, people's demand for information is increasing, and the transmission medium of network data has gradually changed from network to optical fiber transmission. Because optical fiber transmission information has the advantages of large transmission capacity, good confidentiality, speed and convenience. Fiber optic server adapters are used for data transmission of high-end devices such as servers and desktop computers. The fiber server adapter is connected to different ports by the Ethernet controller to realize data conversion and transmission. [0003] The Ethernet controller includes an Ethernet media access controller (MAC layer controller) and a physical layer interface chip (PHY layer controller). The MAC layer controller is the key to achieve flow control. The Et...
