US Patent 7491090 Pluggable optical transceiver with a ground finger

The pluggable optical transceiver of the present invention provides a tailed finger that comes in contact with the inner surface of the cage by pushing outward by the optical connector when the optical connector mates with the optical receptacle. While, when the optical receptacle of the transceiver is free from the optical connector, the tailed finger protrudes into the optical receptacle and no influence is affected to insert the transceiver into or to extract the transceiver from the cage.
