Abstract
A network tap comprises a set of optical signal regeneration circuits and a failover circuit. The set of optical signal regeneration circuits is configured to convert an input optical signal from one network device to an electromagnetic signal and generate output optical signals for another network device and for a monitoring device from the electromagnetic signal. The failover circuit is configured to provide the input optical signal to the set of optical signal generation circuits in a normal mode and provide the input optical signal to the other network device in a failure mode.
Claims18
A network tap, comprising:
- a first set of one or more connectors configured to connect to a first network device;
- a second set of one or more connectors configured to connect to a second network device;
- a third set of one or more connectors configured to connect to a monitoring device;
- a set of one or more optical signal regeneration circuits;
- and
- a failover circuit configured to receive a first optical input signal from said first set of one or more connectors and provide said first optical input signal to said set of one or more optical signal regeneration circuits in a normal mode and to said second set of one or more connectors in a failure mode and further configured to receive a second optical input signal from said second set of one or more connectors and provide said second optical input signal to said set of one or more optical signal regeneration circuits in said normal mode and to said first set of one or more connectors in said failure mode,
- wherein said set of one or more optical signal regeneration circuits is configured to receive said first optical input signal from said failover circuit, convert said first optical input signal to a first set of one or more electromagnetic signals, generate a first optical output signal and a second optical output signal from said first set of one or more electromagnetic signals and provide said first optical output signal to said second set of one or more connectors and said second optical output signal to said third set of one or more connectors, and
- said set of one or more optical signal regeneration circuits is further configured to receive said second optical input signal from said failover circuit, convert said second optical input signal to a second set of one or more electromagnetic signals, generate a third optical output signal and a fourth optical output signal from said second set of one or more electromagnetic signals and provide said third optical output signal to said first set of one or more connectors and said fourth optical output signal to said third set of one or more connectors.
