Abstract: A method for synchronizing clocks, including: receiving at least two clock signals, where the at least two clock signals are sent by a bidirectional clock tracking link respectively corresponding thereto; setting two or more clock signals coming from a same network element into a same clock source group; selecting one clock signal in a same clock source group as a currently tracked clock signal; and if the currently tracked clock signal belongs to the clock source group, respectively sending a standby clock signal carrying quality-level do not use information by using the bidirectional clock tracking link respectively corresponding to each of the clock signals in the clock source group. The present invention achieves the effect that in the scenario where there are two or more bidirectional clock tracking links between two network elements, a clock tracking loop will not be generated.

Abstract: An optical cage assembly includes a box-like housing, a radiator, and a cover-like fastener. The box-like housing has a slot. A first housing wall of the box-like housing has an opening at a position close to a slot opening of the slot. The radiator is located at the opening and can be bonded to an electrical connector plugged into the slot. The cover-like fastener is fastened to housing walls of the box-like housing, and the cover-like fastener has a memory alloy member, where the memory alloy member is located on a surface that is of the radiator and that is away from the opening. In this disclosure, easy plugging and unplugging of an optical module in the slot can be implemented, heat transfer between the radiator and the optical module can be accelerated, and an effect of heat dissipation for the optical module can be enhanced.
