Abstract

Abstract Within a common housing are mounted an autonomous light transmitter having its own transmitter optical coupling element, an autonomous light receiver, a part for connecting a common optical fiber to the common housing, and a beam splitter arranged in the beam path within the common housing. The autonomous light transmitter and the autonomous light receiver are each within their own hermetically sealed encapsulations and it is these hermetically sealed autonomous components which are mounted within the common housing.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 183 words
A transmission and reception module for bi-directional message transmission, comprising: a hollow common housing enclosing a beam path within said hollow common housing; an autonomous light transmitter component mounted in said common housing to transmit light along said beam path within said common hollow housing; a first hermetically tight encapsulation surrounding said autonomous light transmitter component; a transmitter optical coupling element mounted in said common housing in said beam path of light emitted from said autonomous light transmitter component; an autonomous light receiver component mounted in said common housing to receive light transmitted along said beam path in air within said common hollow housing; a second hermetically tight encapsulation surrounding said light receiver component; an optical fiber connector mounted on said common housing by which a common optical fiber may be connected to said housing in said beam path; and a beam splitter mounted in said common housing and arranged intermediately in said beam path for light entering or leaving said optical fiber; said common hollow housing surrounding said autonomous light transmitter component and said transmitter optical coupling element and said beam splitter.
Claim 2
Dependent Claim 183 words
A transmission and reception module for bi-directional message transmission, comprising: a hollow common housing enclosing a beam path within said hollow common housing; an autonomous light transmitter component mounted in said common housing to transmit light along said beam path within said common hollow housing; a first hermetically tight encapsulation surrounding said autonomous light transmitter component; a transmitter optical coupling element mounted in said common housing in said beam path of light emitted from said autonomous light transmitter component; an autonomous light receiver component mounted in said common housing to receive light transmitted along said beam path in air within said common hollow housing; a second hermetically tight encapsulation surrounding said light receiver component; an optical fiber connector mounted on said common housing by which a common optical fiber may be connected to said housing in said beam path; and a beam splitter mounted in said common housing and arranged intermediately in said beam path for light entering or leaving said optical fiber; said common hollow housing surrounding said autonomous light transmitter component and said transmitter optical coupling element and said beam splitter.
Claim 3
Dependent Claim 40 words
A transmission and reception module as claimed in claim 1, further comprising: a receiver optical coupling element mounted in said beam path of light entering said light receiver component, said receiver optical coupling element being contained within said second encapsulation.
Claim 4
Dependent Claim 30 words
A transmission and reception module as claimed in claim 1, further comprising: a fiber optical coupling element mounted in said common housing in said beam path of the optical fiber.
Claim 5

Claim 8
Dependent Claim 19 words
A transmission and reception module as claimed in claim 1, wherein said optical fiber connector is a plug jack.
Claim 9
Dependent Claim 19 words
A transmission and reception module as claimed in claim 1, wherein said beam splitter is a proportional beam splitter.
Claim 10
Dependent Claim 19 words
A transmission and reception module as claimed in claim 1, wherein said beam splitter is a frequency-selective beam splitter.
Claim 11
Dependent Claim 24 words
A transmission and reception module as claimed in claim 1, wherein said transmission optical coupling element is mounted within said first hermetically tight encapsulation.
Claim 12
Dependent Claim 24 words
A transmission and reception module as claimed in claim 1, wherein said transmitter optical coupling element is mounted outside said first hermetically tight encapsulation.
Claim 13
Dependent Claim 24 words
A transmission and reception module as claimed in claim 1, wherein said transmitter optical coupling element forms part of said first hermetically tight encapsulation.
Claim 14
Dependent Claim 18 words
A transmission and reception module as claimed in claim 1, wherein said common hollow housing is of metal.
