Abstract: A containing device for affixing a plurality of optical transceivers is provided, wherein each of the optical transceivers includes a first surface and a second surface opposite to the first surface. The containing device includes a housing and a passage formed in the housing. The passage has a first abutting surface and a second abutting surface. The optical transceivers are disposed in the passage. When the containing device moves along a first direction relative to the optical transceivers, the first abutting surface contacts the first surfaces of the optical transceivers. When the containing device moves along a second direction relative to the optical transceivers, the second abutting surface contacts the second surfaces of the optical transceivers, wherein the first direction is opposite to the second direction.
