Integrated Fiber Optic Receiver Power Meter
US Patent:
6627867, Sep 30, 2003
Filed:
Nov 20, 2001
Appl. No.:
09/989826
Inventors:
Stephen John Ames - Rochester MN
Michael William Marlowe - Rochester MN
Christopher K. White - Rochester MN
Michael William Marlowe - Rochester MN
Christopher K. White - Rochester MN
Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H01J 4014
US Classification:
250214R, 359152
Abstract:
An apparatus, circuit arrangement and method enable a host system to read a signal that is proportional to the peak-to-peak optical power incident on a transceiver at one end of a fiber optic link without breaking that link. By reading this signal and being aware of the characteristics of the laser, the âhealthâ of the laser is known and the integrity of the link is maintained. Consequently, the host system has a predictive tool that is able identify substandard lasers so that such lasers can be replaced before serious, and potentially costly, data disruptions occur.
Laser Diode Monitoring Via Current Mirroring
US Patent:
6661817, Dec 9, 2003
Filed:

Appl. No.:
09/955545
Inventors:

Assignee:
International Business Machines Corporation - Armonk NY
International Classification:
H01S 50683
US Classification:
372 29021
Abstract:
An apparatus, program product and method enable a host system to read a signal or signals that are proportional to the output power and/or the bias of a laser in a fiber optic link connected to that host system without breaking that link. By reading one or more of these signals and being aware of the laser characteristics, the âhealthâ of the laser is known and the integrity of the link is maintained. Consequently, the host system has a predictive tool which is able identify substandard lasers and replace them before a serious, and potentially costly, data disruption occurs.
Detection Of Data Transmission Rates Using Passing Frequency-Selective Filtering

International Classification:
H04B 10/08, H04B 17/00, H04B 3/46, H04B 10/06, H04Q 1/20
US Classification:
398 25, 375225, 324 7641, 324 7647, 398202
Abstract:
A data receiver, which could be an optical transceiver, a modem, a router hub, is capable of detecting the transmission rate of incoming data. The data is converted to electrical waves appropriate for passive or active bandpass filtering. The frequencies at which the waves are filtered are determined from a plurality of known possible transmission rates and are chosen as having the most detectable difference in the power spectra. By implementing a filter at the corresponding frequency(ies), data having that (those) frequency(ies) will be transmitted. A signal detector then can receive a signal transmitted through the filter and determine the corresponding data rate. It is further contemplated that the multiple frequencies can be filtered by using stages of filters and signal detectors for different frequencies or by filters and detectors capable of multiple frequency operation.
Lonely Pulse Compensation
US Patent:

Assignee:
Cray Inc. - Seattle WA
International Classification:
H04L 12/66
US Classification:
370463, 455266
Abstract:
An apparatus comprising a transmission line, a receiver circuit, and a high pass filter circuit coupled between the transmission line and a receiver circuit input. The receiver circuit is configured to receive a data signal over the transmission line at a first data rate. The high pass filter circuit is connected between the transmission line and a receiver circuit input and has a corner frequency that is less than approximately the first data rate and is greater or equal to than approximately one-half the second data rate. The second data rate is an effective data rate caused by an expected data pattern on the transmission line. Other devices, systems, and methods are disclosed.
