54. A pluggable optical transceiver mounted on a host system, comprising:
an optical receptacle for receiving an external connector; and
a mechanism that prevents said optical transceiver from releasing from said host system when said optical receptacle receives an external connector and prevents said optical transceiver from receiving said external connector when said optical transceiver is free from said host system.
55. A pluggable optical transceiver mounted on a host system, comprising:
an optical receptacle for receiving an external connector;
a screw latch for fastening said optical transceiver with said host system; and
a housing for installing said optical receptacle,
wherein said optical receptacle is prevented to receive said external connector when said optical transceiver is free from said host system.
56. The pluggable optical transceiver of claim 55,
further comprising a latch bar for mechanically coupling said optical receptacle with said screw latch,
wherein said latch bar protrudes in one end thereof into said optical receptacle to prevent said optical receptacle from receiving said external connector when said screw latch is disengaged with said host system.
57. The pluggable optical transceiver of claim 56,
wherein said one end of said latch bar has an arched shape.
58. The pluggable optical transceiver of claim 56,
wherein said screw latch provides a groove to receive another end of said latch bar when said optical receptacle receives said external connector.
59. The pluggable optical transceiver of claim 56,
wherein said screw latch pushes another end of said latch bar to protrude said end into said optical receptacle.
60. The pluggable optical transceiver of claim 56,
wherein said latch bar provides an elastic portion, and said housing provides a groove to set said elastic portion thereon, and
wherein said latch bar recovers an original position thereof by an elastic force caused in said elastic portion and said groove.
61. The pluggable optical transceiver of claim 56,
wherein said optical receptacle provides a cut for passing said one end of said latch bar.
62. The pluggable optical transceiver of claim 55,
wherein said screw latch is prevented to disengage with said host system when said optical receptacle receives said external connector.
63. The pluggable optical transceiver of claim 62,
further comprising a latch bar for mechanically coupling said optical receptacle with said screw latch,
wherein said latch bar is pushed in one end thereof by said external optical connector received by said optical receptacle and protrudes in a groove provided in said screw latch to prevent said screw latch from sliding.
64. The pluggable optical transceiver of claim 63,
wherein said one end of said latch bar has an arched shape.
65. The pluggable optical transceiver of claim 63,
wherein said latch bar has an elastic portion, and said housing provides a groove to receive said elastic portion therein, and
wherein said one end of said latch bar automatically protrudes into said optical receptacle by an elastic forces of said elastic portion in said groove.
66. The pluggable optical transceiver of claim 62,
wherein said optical receptacle provides a cut for passing said one end of said latch bar.
67. The pluggable optical transceiver of claim 55,
wherein said screw latch provides a flange and a coil spring, and said housing provides a groove for setting said screw latch, and
wherein said screw latch recovers an original position by said coil spring set in said groove when said screw latch is disengaged with said host system.
