| 摘要 |
Embodiments of the present invention provide a method for detecting a receive end, a detection circuit, an optical module, and a system, and relate to the field of optical communications. The method includes: transmitting a first detection code pattern to a PCI-E receive end through optical transmission, so that after receiving the first detection code pattern, the PCI-E receive end feeds back a second detection code pattern through the optical transmission; detecting whether the second detection code pattern fed back by the PCI-E receive end through the optical transmission is received; and determining that the PCI-E receive end is in position if a detection result is that the second detection code pattern fed back by the PCI-E receive end through the optical transmission is received. The present invention resolves a problem that receive end detection cannot be implemented by using a conventional method in a PCI-E bus that supports optical transmission, and achieves an effect that receive end detection can also be implemented in a PCI-E bus that supports optical transmission. |
