Abstract

The present disclosure provides integrated performance monitoring (PM); optical layer operations, administration, maintenance, and provisioning (OAM&P); and alarming in optical transceivers, such as multi-source agreement (MSA)-defined modules. The present disclosure includes an optical transceiver defined by an MSA agreement with integrated PM and alarming for carrier-grade operation. The integration preserves the existing MSA specifications allowing the optical transceiver to operate with any compliant MSA host device. Further, the host device can be configured through software to retrieve the PM and alarming from the optical transceiver. The optical transceiver can include CFP and variants thereof (e.g., future CFP2, CDFP, CXP), OIF-MSA-100GLH-EM-01.0, CCRx (Compact Coherent Receiver), Quad Small Form-factor Pluggable (QSFP) and variants thereof (e.g., future QSFP+, QSFP2), 10×10 MSA, XFP, XPAK, XENPAK, X2, XFP-E, SFP, SFP+, 300-pin, and the like.

Claims (27)

1. An optical transceiver according to a multi-source agreement, comprising:

circuitry configured to provide framing and forward error correction integrated within the optical transceiver;

transmit optics coupled to the circuitry;

receive optics coupled to the circuitry;

a housing, wherein the circuitry, the transmit optics, and the receive optics are disposed in or on the housing, and wherein the housing is compliant to the multi-source agreement; and

a controller communicatively coupled to the circuitry, wherein the controller is configured to communicate to the host system via a management data input/output (MDIO) interface or I2C, wherein the controller is configured to communicate data related to operations, administration, maintenance, and provisioning and the framing and forward error correction via the MDIO or I2C interface;

wherein the multi-source agreement defines one of a 40G or 100G optical transceiver;

wherein the optical transceiver is configured to operate within a host system according to the multi-source agreement; and

wherein the data is communicated via undefined or reserved registers in the MDIO or I2C interface thereby preserving the multi-source agreement.

2. The optical transceiver of claim 1 , further comprising:

a controller communicatively coupled to the circuitry; and

a communications port disposed on the optical transceiver and communicatively coupled to the controller, wherein the controller is configured to communicate data related to operations, administration, maintenance, and provisioning and the framing and forward error correction via the communications port.

3. The optical transceiver of claim 1 , wherein the framing is compliant to G.709.

4. A 40G/100G optical transceiver, comprising:

an optical section comprising transmit optics and receive optics;

an electrical section communicatively coupled to the optical section;

circuitry in the electrical section configured to provide framing and forward error correction integrated within the 40G/100G optical transceiver and transparent to a host system housing the 40G/100G optical transceiver;

a controller communicatively coupled to the optical section, the electrical section, and the host system; and

a housing, wherein the optical section, the electrical section, and the controller are disposed in or on the housing, and wherein the housing is compliant to the multi-source agreement;

wherein the 40G/100G optical transceiver is according to a multi-source agreement;

wherein the multi-source agreement comprises one of OIF MSA-100GLH, CCRx, or 10×10.

5. The 40G/100G optical transceiver of claim 4 , further comprising a communications port disposed on the 40G/100G optical transceiver and communicatively coupled to the controller.

6. The 40G/100G optical transceiver of claim 5 , where the communications port is configured to communicate data related to the framing and the forward error correction.

7. The 40G/100G optical transceiver of claim 5 , where the communications port is configured to communicate data related to operations, administration, maintenance, and provisioning.

8. The 40G/100G optical transceiver of claim 4 , wherein the controller is configured to communicate to the host system via a standardized method according to the multi-source agreement.

9. The 40G/100G optical transceiver of claim 8 , wherein the controller is configured to communicate data related to the framing and the forward error correction to the host system via the standardized method according to the multi-source agreement.

10. The 40G/100G optical transceiver of claim 4 , wherein the framing is compliant to G.709.
