Abstract: In some implementations, an optical receiver includes a polarization beam splitter configured to split a reception signal into a first polarization reception signal and a second polarization reception signal, a first demultiplexing component configured to demultiplex the first polarization reception signal into a first optical signal and a second optical signal associated with a first polarization, a second demultiplexing component configured to demultiplex the second polarization reception signal into a third optical signal and a fourth optical signal associated with a second polarization, a first demodulation component configured to mix the first optical signal and the third optical signal with a first local oscillator signal to demodulate the first optical signal and the third optical signal, and a second demodulation component configured to mix the second optical signal and the fourth optical signal with a second local oscillator signal to demodulate the second optical signal and the fourth optical signal

Abstract: A standalone notification system, including a notification server which generates electronic messages to registered customers upon their request or upon a host business request. The customer provides the system with his/her messaging identification (“ID”), e.g. e-mail address, GSM (global system for mobile communications) or other mobile phone numbers that are able to accept, e.g., short message service (“SMS”) messages, facsimile number, and/or telephone number. Customers can register with the host notification server without having any relationship, banking or otherwise, with the host. Customers can choose between different notification channels such as e-mail, SMS message, fax or pager.

Abstract: A standalone notification system, including a notification server which generates electronic messages for alerting customers of potentially fraudulent activity on one or more of their financial accounts. Alternatively, or in addition thereto, the notification system may be used to forward transaction code(s) to customers for verification of a request for high risk transaction(s) with respect to a customer's financial account. The transaction code is generated in response to a high risk transaction request and sent to through an identified customer notification means, e.g., e-mail, short message service (“SMS”), facsimile, mobile phone, telephone, etc. The customer must enter the transaction code within a predetermined amount of time in order to verify the high-risk transaction request.
