Here, too, significant differences exist. In general, newer modules consume half the real estate of the first generation, although some are even smaller. Reductions in power consumption and heat dissipation are equally, if not more, important. Again, second-generation solutions are about twice as efficient. Even among recent solutions, there are wide disparities in this area.
Modules are available that help solve the heat and power problems.
The module design must be such that it can be built in high volume. Electrical bending of the signal from the card plane to the optical plane is one technique that supports high-volume optics. All rights reserved.
