Abstract

An optical harness assembly and method are provided. The optical harness assembly includes at least one optical harness cable having a termination end; at least one electrical connector having connector pins; and at least one active connector conversion unit coupled between the termination end of the optical harness cable and the electrical connector. The method includes: identifying electrical signals present on each pin of each electrical connector presentation; programmatically adjusting an interface based on the identified electrical signals present; and mapping the electrical connector signals to digital signals. The method may further include: providing a personality adaptor coupled between the electrical connector pin outs and signal conditioners; configuring the personality adaptor based on the identified electrical signals present on each pin out of each electrical connector presentation; and providing configured electrical connector presentation signals to the interface.

Claims

1. A method for adapting electrical presentations of legacy terminal equipment to an active connector conversion unit, comprising:

identifying electrical signals present on each pin of electrical connector presentations of the legacy terminal equipment;

programmatically adjusting firmware loaded into a field programmable gate array (FPGA), between the electrical connector presentation and the active connector conversion unit, based on the identified electrical signals present; and

mapping the electrical connector signals to digital signals.

2. The method of claim 1, wherein the step of identifying comprises testing each pin'"'"'s electrical characteristics.

3. The method of claim 1, wherein the mapping is performed through signal conditioners.

4. A method for adapting electrical presentations of legacy terminal equipment to an active connector conversion unit, comprising:

identifying electrical signals present on each pin of electrical connector presentations of the legacy terminal equipment;

programmatically adjusting an interface, between the electrical connector presentation and the active connector conversion unit, based on the identified electrical signals present;

mapping the electrical connector signals to digital signals;

determining if the electrical connector pin presentation is correctly configured;

if correct, providing configured electrical connector presentation signals to the interface, and

if not correct, readjusting the interface.

5. The method of claim 4, wherein the readjusting step further comprises:

removing the optical harness; and

reprogramming the interface.

6. A method for adapting electrical presentations of legacy terminal equipment to an active connector conversion unit, comprising:

identifying electrical signals present on each pin of electrical connector presentations of the legacy terminal equipment;

programmatically adjusting an interface, between the electrical connector presentation and the active connector conversion unit, based on the identified electrical signals present;

mapping the electrical connector signals to digital signals;

providing a personality adaptor coupled between the electrical connector pins and signal conditioners of the active connector conversion unit;

providing configured electrical connector presentation signals to the interface.

7. The method of claim 6, wherein the personality adaptor is coupled to FPGAs.

8. A method for adapting electrical presentations of legacy terminal equipment to an active connector conversion unit having signal conditioners, comprising:

identifying electrical signals present on each pin of electrical connector presentations of the legacy terminal equipment;

providing a personality adaptor coupled between the electrical connector pins and signal conditioners of the active connector conversion unit;

configuring the personality adaptor based on the identified electrical signals present on each pin of each electrical connector presentation;

programmatically adjusting an interface between the electrical connector presentation and the active connector conversion unit based on the identified electrical signals present;

mapping the electrical connector signals to digital signals;

determining if electrical connector pin presentation is correctly configured; and

if correct, providing configured electrical connector presentation signals to the interface,

if not correct, readjusting the interface.

9. The method of claim 8, wherein the readjusting step further comprises:

removing the optical harness; and

rewiring the personality adaptor.
