Before I could add any input here I'd rather get more
questions off my back.
- Bend Radius of cable options
- Bend radius of cable options when multiple cables in a
modular design get merged together? And the stress that produces on the
card?
- Room for LEDS on either side of the connectors and still
fit in the PCI form-factor?
- EMI performance modelled? Common mode impedance/s-params
simulations?
- Keying options? Even though we shouldn't have
them...
- Release mechanisms push-pull? Does it
matter?
- Heatsink capabilities on connector
body?
- Color coding the body of the
cable/connector?
If the design was modular, a power pin per x4 block would
answer alot of your questions below. As would using I2C or other such 2 wire/3
wire management interfaces on a per x4 block design.

considerations
Feedback from users would help to
narrow the selection field and number of proposals to better fit the application
model. In addition to the posting by Alvin Cox regarding the input from the
November t10 meeting, a few opinions would be extremely helpful. Please consider
both internal and external applications.

Is a modular design favored over a set number of
connections?
This would likely consist of 4x blocks and could allow for multiple cables or
different single cables that have the 4x, 8x, 12x, 16x configurations.
Trade-off of
modular may be encountered due to area.
Suggestions for sideband support?
Separate module?
Include in one module?
Duplicate on all modules?
Partial or all lines?
Sidebands?
How many required for internal and external?
Does external provide more
information than just cable power and type?
Power requirements?
How much power is required for a 16x configuration?
Copper
Optical
What voltage and
current?
