Description

Optical transmission apparatus

Technical Field

The utility model relates to the technical field of computers, in particular to optical transmission equipment.

Background

Currently, the network chip connection to the optical transceiver is mainly implemented by a serial interface, and a part of the network chip connection is performed by the serial gigabit port physical layer chip controller 102 to convert the serial interface. But most chips cannot connect directly to a gigabit port through a serial interface. And the chip to be led out of the 1Gb SFP must be connected with a specific chip and a basic input and output system through a Serial Gigabit Media Independent Interface (SGMII), and the connection is realized by applying a local area network configuration.

When the main chip 100 group does not have a serial interface, or the SGMII fibre channel protocol function does not support, or the main chip 100 group does not support the fibre channel protocol, the gigabit optical port cannot be connected. In addition, because the chip can not be replaced to achieve gigabit connection after selecting the matched chip, the problems of high cost, long stocking time, increased stocking capital pressure and the like are easily caused.

In view of the above problems, no effective solution has been proposed.

Example 1

In the prior art, partial chips to be led out of 1Gb SFP must be connected with a specific chip through a Serial Gigabit Media Independent Interface (SGMII). For example, fig. 1 shows a hardware structure diagram of implementing gigabit optical connection by an intet C30000 chip, and to extract a 1Gb SFP from the intet C30000 chip, the intet C30000 chip must connect the miwei 88E1543 PHY chip and the basic input/output system through a Serial Gigabit Media Independent Interface (SGMII), and use the local area network configuration LEK8 for implementation.
