Abstract

The present invention is provided with an optical module and a method of the optical module to support GE optical port and FE optical port. The optical module comprises a serialization and solving serialization Serdes interface and an inner placed physical layer device PHY. The PHY provides the signal between the serial gigabit medium independence interface SGMII and the optical module, and supports the fast ethernet FE optical port or gigabit ethernet FE optical port. The technical scheme provided by the invention makes the optical module output GE optical port or FE optical port according to requirement, and new functions are compatible on the base of the existing development veneer. Outputting FE optical port avoids modifying the chip frequently and reduces the kinds of veneer with same function. Meanwhile, the cost of the GE interface is optimal.

Description

technical field [0001] The invention belongs to the technical field of Ethernet, in particular to the transmission interface technology in Ethernet. Background technique [0002] Ethernet is one of the types of computer local area network, which is mainly composed of several sites (network nodes), devices connected to the network, and various transmission media for transmitting information between sites. As a basic medium (media) access technology of LAN, Ethernet has developed rapidly in recent years because of its high flexibility and simplicity of implementation. [0003] The standard of wired Ethernet has been developed so far, and the rate has risen from 10Mbit / s to 10Gbit / s. The standard has reached the plug-and-play level in terms of compatibility, making it a widely used network technology. Wired Ethernet can realize different working modes (half-duplex, full-duplex), different working speeds (10Mbit / s, 100Mbit / s, 1Gbit / s or 10Gbit / s) and different transmissions by ...
