Patent ID: 11894916
Assignee: ECI TELECOM LTD.
Field: Telecommunications (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A method of optical network management, comprising:
connecting a first egress port of an optical amplifier to an optical network, the first egress port configured to provide first optical output transmissions in the multiple transmission bands;
connecting a second egress port of an amplifier noise source to a first port of first ingress ports of the optical amplifier, the first ingress ports configured to receive optical transmissions in multiple transmission bands, the first port of the first ingress ports configured to receive a first optical input transmission in a first band of the multiple transmission bands; and
wherein a second ingress port of the amplifier noise source is configured to:
receive a second optical input transmission in the first band; and
generate the first optical input transmission by amplifying a combination of a bulk noise and the second optical input transmission, a magnitude of the amplification being dependent on a power of the second optical input transmission.
