Patent ID: 7387527

Claim:
A pluggable optical transceiver module comprising: a housing frame having an adaptor at which an optical transceiver element is installed; a rotary lever comprising a handle at one side and a pressing portion at another side; a coupling protrusion formed on the modular housing frame for fixing the pluggable optical transceiver module to a receiving receptacle by way of a clamp on the receiving receptacle; an elastic arm pivoted on the housing frame to be rotated by the rotary lever, the elastic arm comprising one end contacting the pressing portion according to rotation of the rotary lever and a second end coupled with or separated from the clamp of the receiving receptacle; and wherein the rotary lever pressing portion pivots the elastic arm, wherein the elastic arm moves laterally towards the coupling protrusion guided by a fixing sill and a second end of the elastic arm elastically bends and slants by a predetermined angle when the rotary lever pressing portion presses the one end of the elastic arm, wherein the second end of the elastic arm becomes repulsive with respect to the clamp of the receptacle due to the slant, and wherein the elastic arm de-couples the clamp of the receiving receptacle from the coupling protrusion allowing for removal of the pluggable optical transceiver module.
