Patent ID: 8646992

Claim:
A receptacle structure for optical sub-assembly for transceivers, an optical fiber module being pluggable into the receptacle structure to optically connect therewith for transmitting optical signals, the receptacle structure comprising: a receiving tube having an internal first receiving hole at a front end, an internal second receiving hole and an internal connection hole at a rear end, in which the optical fiber module can be plugged to connect with the receiving tube; an optical fiber having a front end section and a rear end section; an optical fiber retainer member having an interface section and an inclined head integrally connected with the interface section, the interface section being mounted in the first receiving hole of the receiving tube with the inclined head protruding out of the receiving tube at front end of the optical fiber retainer member, the interface section defining a third receiving hole and a fourth receiving hole, the inclined head defining an inclined hole for receiving the front end section of the optical fiber, the front end section of the optical fiber being disposed in the inclined head in an inclined state, whereby the optical signals can be mass-accumulated and coupled to the optical fiber; a sleeve mounted in the second receiving hole of the receiving tube and the third receiving hole of the optical fiber retainer member, the sleeve being formed with an internal through hole for receiving a front end section of the optical fiber module; and a fiber stub mounted in the fourth receiving hole of the optical fiber retainer member and the through hole of the sleeve, the fiber stub having a passageway for receiving the rear end section of the optical fiber.
