Abstract

This disclosure concerns optoelectronic transceivers. In one example, a transceiver is implemented as an uncompensated architecture that is substantially compliant with the SFP MSA and is capable of effective operation at a data rate of about 8.5 Gb/s. The transceiver includes a TOSA, ROSA, a printed circuit board, an LDPA disposed on the printed circuit board and configured for communication with the TOSA and the ROSA. Finally, the transceiver includes SFP compliant optical and electrical connections.

Claims (37)

1. A transceiver module, comprising:

an uncompensated architecture that does not implement clock and data recovery (CDR) compensation and is configured to transmit and receive data at a rate of about 8.5 Gb/s, the uncompensated architecture including:

a TOSA;

a ROSA;

a printed circuit board having an SFP electrical connector configured for communication with a host;

an LDPA disposed on the printed circuit board and configured for communication with the TOSA and the ROSA; and

at least one optical connector in communication with at least one of: the ROSA; and, the TOSA.

2. The transceiver module as recited in claim 1 , wherein the uncompensated architecture is compliant with the SFP MSA.

3. The transceiver module as recited in claim 1 , wherein the TOSA and the ROSA are each capable of performing at a data rate of about 10 Gb/s.

4. The transceiver module as recited in claim 1 , wherein the TOSA includes one of: a DFB laser; an 850 nm VCSEL; and, an FP laser.

5. The transceiver module as recited in claim 1 , wherein the ROSA includes an 850 nm P-I-N detector and preamp.

6. The transceiver module as recited in claim 1 , wherein the transceiver module dissipates less than about one watt of power during operation.

7. The transceiver module as recited in claim 6 , wherein the transceiver module dissipates less than about 600 milliwatts of power during operation.

8. The transceiver module as recited in claim 6 , wherein the transceiver module dissipates less than about 800 milliwatts of power during operation.

9. The transceiver module as recited in claim 1 , wherein, during operation, the transceiver module maintains compliance with a standard eye diagram requirement.

10. A transceiver module, comprising:

an architecture that is compliant with the SFP MSA and that is configured to transmit and receive data at a rate of about 8.5 Gb/s, wherein the architecture includes:

a TOSA;

a ROSA;

a printed circuit board having an SFP electrical connector configured for communication with a host;

an LDPA disposed on the printed circuit board and configured for communication with the TOSA and the ROSA; and

at least one optical connector in communication with at least one of: the ROSA; and, the TOSA.

11. The transceiver module as recited in claim 10 , wherein the TOSA and the ROSA are each capable of performing at a data rate of about 10 Gb/s.

12. The transceiver module as recited in claim 10 , wherein the TOSA includes one of: a DFB laser; an 850 nm VCSEL; and, an FP laser.

13. The transceiver module as recited in claim 10 , wherein the ROSA includes an 850 nm P-I-N detector and preamp.

14. A transceiver module, comprising:

an uncompensated architecture that does not include CDR circuitry and is configured to transmit and receive data at a rate of about 8.5 Gb/s, the uncompensated architecture including:

a TOSA;

a ROSA;

a printed circuit board having a first side and a second side opposing the first side and an SFP electrical connector configured for communication with a host;

an LDPA disposed on the first side of the printed circuit board and configured for communication with the TOSA and the ROSA;

a DCC disposed on the second side of the printed circuit board that interfaces with the LDPA and with external device to provide diagnostics; and

at least one optical connector in communication with at least one of: the ROSA; and, the TOSA.

15. The transceiver module as recited in claim 14 , wherein the uncompensated architecture is compliant with the SFP MSA.

16. The transceiver module as recited in claim 14 , wherein the TOSA and the ROSA are each capable of performing at a data rate of about 10 Gb/s.

17. The transceiver module as recited in claim 14 , wherein the TOSA includes one of: a DFB laser; an 850 nm VCSEL; and, an FP laser.

18. The transceiver module as recited in claim 14 , wherein the ROSA includes an 850 nm P-I-N detector and preamp.
