Abstract

An optical connector including: a plug housing having a pin cavity; a pin disposed at least partially in the pin cavity of the plug housing, the pin comprising at least a pin sleeve; a receptacle housing having a socket cavity; a socket disposed at least partially in the socket cavity, the socket comprising at least a socket sleeve; and an alignment sleeve between said pin and socket, wherein the plug housing, the pin, the pin sleeve, the pin ferrule, the receptacle housing, the socket, the socket sleeve, the socket ferrule, and the alignment sleeve: (i) magnetic permeability that is less than 1.0 B/H, where B is magnetic flux density and H is magnetic flux, and (ii) are configured to perform at least 100,000 mating cycles.

Claims (42)

1. A first optical connector system configured to couple to a second optical connector system, the first optical connector system comprising:

a connector system housing, the connector system housing being configured to shield internal components from external and internal electro-magnetic interference;

a mixed-mode electrical component insert disposed in the connector system housing and configured to receive a first set of mixed-mode electrical lines and couple the first set of mixed-mode electrical lines to a second set of mixed-mode electrical lines disposed in the second optical connector system;

a control signal component insert disposed in the connector system housing and configured to receive a first set of control signal lines and couple the first set of control signal lines to a second set of control signal lines disposed in the second optical connector system; and

an expanded beam (EB) fiber-optical connector component insert disposed in the connector system housing and configured to receive a first portion of an optical connector and couple the first portion of the optical connector to a second portion of the optical connector,

wherein the connector system housing, the mixed-mode electrical component insert, the control signal component insert, and the EB fiber-optical connector component:

(i) have a magnetic permeability that is less than 1.0 B/H, where B is magnetic flux density and H is magnetic flux, and

(ii) are configured to perform at least 100,000 mating cycles,

wherein the first portion of the optical connector includes:

a plug housing having a pin cavity;

a pin disposed at least partially in the pin cavity of the plug housing, the pin comprising at least a pin sleeve, said pin sleeve at least partially containing a pin ferrule and a pin lens;

a receptacle housing having a socket cavity:

a socket disposed at least partially in the socket cavity, the socket comprising at least a socket sleeve, the socket sleeve at least partially containing a socket ferrule and a socket lens; and

an alignment sleeve removably couplable between said pin and socket, wherein a pin front portion of said pin sleeve and a socket front portion of said socket sleeve are disposable in said alignment sleeve,

wherein the plug housing, the pin, the pin sleeve, the pin ferrule, the receptacle housing, the socket, the socket sleeve, the socket ferrule, and the alignment sleeve:

(i) have a magnetic permeability that is less than 1.0 B/H, where B is magnetic flux density and H is magnetic flux, and

(ii) are configured to perform at least 100,000 mating cycles.

2. The optical connector of claim 1 , wherein the plug housing, the pin, the pin sleeve, the pin ferrule, the receptacle housing, the socket, the socket sleeve, the socket ferrule, and the alignment sleeve include a metal component selected from the group consisting of aluminum, silver, tin, phosphor bronze, brass, copper, gold, lead, titanium, silicon bronze, cobalt-chromium, beryllium copper, non-magnetic stainless steel and various alloy combinations thereof.

3. The optical connector of claim 1 , wherein the metal component includes a base metal, subplating, and final plating, each selected from the group consisting of aluminum, silver, tin, phosphor bronze, brass, copper, gold, lead, titanium, silicon bronze, cobalt-chromium, beryllium copper, non-magnetic stainless steel and various alloy combinations thereof.

4. The optical connector of claim 1 ,

wherein the plug housing, the pin, the pin sleeve, and the pin ferrule include a first metal component selected from the group consisting of aluminum, silver, tin, phosphor bronze, brass, copper, gold, lead, titanium, silicon bronze, cobalt-chromium, beryllium copper, non-magnetic stainless steel and various alloy combinations thereof,

wherein the receptacle housing, the socket, the socket sleeve, and the socket ferrule include a second metal component selected from the group consisting of aluminum, silver, tin, phosphor bronze, brass, copper, gold, lead, titanium, silicon bronze, cobalt-chromium, beryllium copper, non-magnetic stainless steel and various alloy combinations thereof, and

wherein the second metal component is separate and distinct from the first metal component.

5. The first optical connector system of claim 1 , wherein a metal portion of the optical connector having greater malleability than metal portions of the connector system housing.

6. The first optical connector system of claim 1 , wherein the connector system housing, the mixed-mode electrical component insert, the control signal component insert, the keying and polarizing component insert, and the EB fiber-optical connector component each includes a base metal, subplating, and final plating, each selected from the group consisting of aluminum, silver, tin, phosphor bronze, brass, copper, gold, lead, titanium, silicon bronze, cobalt-chromium, beryllium copper, non-magnetic stainless steel and various alloy combinations thereof.

7. A first optical connector system configured to couple to a second optical connector system, the first optical connector system comprising:

a connector system housing, the connector system housing being configured to shield internal components from external electro-magnetic interference;

a mixed-mode electrical component insert disposed in the connector system housing and configured to receive a first set of mixed-mode electrical lines and couple the first set of mixed-mode electrical lines to a second set of mixed-mode electrical lines disposed in the second optical connector system;

a control signal component insert disposed in the connector system housing and configured to receive a first set of control signal lines and couple the first set of control signal lines to a second set of control signal lines disposed in the second optical connector system; and

an EB fiber-optical connector component insert disposed in the connector system housing and configured to receive a first portion of an optical connector and couple the first portion of the optical connector to a second portion of the optical connector,

wherein the optical connector includes:

a plug housing having a pin cavity;

a pin disposed at least partially in the pin cavity of the plug housing, the pin comprising at least a pin sleeve, said pin sleeve at least partially containing a pin ferrule and a pin lens;

a receptacle housing having a socket cavity;

a socket disposed at least partially in the socket cavity, the socket comprising at least a socket sleeve, the socket sleeve at least partially containing a socket ferrule and a socket lens; and

an alignment sleeve removably couplable between said pin and socket, wherein, a pin front portion of said pin sleeve and a socket front portion of said socket sleeve are disposable in said alignment sleeve,

wherein the plug housing, the pin, the pin sleeve, the pin ferrule, the receptacle housing, the socket, the socket sleeve, the socket ferrule, and the alignment sleeve:
