Patent EP-0397369-A3 (EP)
Title: Optical apparatus for combining light beam arrays having different wavelengths
IPC: H04B10/29
Filed: 1990-05-01
Abstract: Optical apparatus for performing wavelength-dependent beam 
combination. The apparatus relies on a 
polarization beam splitter (11) in combination 
with other optical elements to develop 
combined beams with the same polarization 
type and that are therefore suitable 
for polarization-dependent combination with 
other beam arrays. A dichroic mirror (243), 
which is used as the wavelength-dependent 
element of the apparatus, is oriented 
such that the incident beams are substantially 
perpendicular to the mirror. With this 
orientation, the dichroic mirror achieves 
near-ideal performance even with beam 
arrays having a substantial angular field. 
The apparatus also uses two plates (244, 242) which, 
although designed for operation as 
quarter-wave plates at one of the two 
wavelengths being combined, are oriented with 
their respective fast axes substantially 
perpendicular to each other such that 
polarization conversions, effected by the 
plates on beams having the other of the two 
wavelengths, substantially cancel each other.

Patent EP-0719058-A3 (EP)
Inventor: COHEN LEONARD GEORGE
IPC: G02B6/24
Filed: 1995-12-06
Abstract: The present invention includes a system for tracing jumpers (8) used in an exchange (1)
to cross-connect optical fibers or wires served by the exchange. The system includes
an exchange housing receptacles (6) with optically-encoded data (9) associated with each
receptacle or a group of receptacles. The optically-encoded data (9) for a receptacle(s)
uniquely identifies the physical location of the receptacle from any other receptacle in
the exchange. Also, this optically-encoded data (9) can include the type of jumper (8) and/or
length of the jumper to be used with the receptacle, the correct routing of the jumper
through the exchange, the traffic to be carried on the jumper and/or the identity of the
physical location of the receptacle to be connected to the other end of the jumper.
Likewise, the jumpers each have optically-encoded data formed thereon that uniquely
identifies the jumper or jumper end and distinguishes the jumper from any other jumper
used in the exchange. The optically-encoded data (9) associated with the jumper can
include the type of jumper, the length of the jumper, the proper routing of the jumper
through the exchange and/or the traffic to be carried on the jumper. If no jumper is to
be connected to a particular receptacle (6), a cover with optically-encoded data can be
attached to a receptacle to indicate that no jumper is connected to the receptacle. The
system of this invention also includes a hand-held optical scanner (14) that can be used by
an operator to scan the optically-encoded data associated with a receptacle(s) and the
optically-encoded data of a jumper(s) connected to the receptacle(s), and transmits the
optically-encoded data signals to a computer (15) of the system of this invention. The
computer can generate a display of the physical location of a receptacle(s) in association
with the identity of the jumper(s) and connected thereto, so that an operator can
diagnose misconnections of the jumpers between receptacles in the exchange. Further,
the computer can store verification data that can be compared with optically-encoded
data signals from scanning with the optical scanner, to determine whether the proper
jumper has been connected to a receptacle, whether the jumper is of appropriate type or
length for the cross-connection and whether the jumper or receptacle is associated with
traffic that is of interest to the operator, for example.
