I have a 1gb switch internally and purchased this owc external 10gb adapter. my speeds still are not good. do i need to bypass the internal 1gb?

Not sure what you are asking exactly but if you connect a water hose to a fire hydrant, it will only flow at the volume of the water hose... The full path should be 10gb.

does this work for usb-c and can i use a usb-c to usb-a cable for usb 3.0 type a cable into usb 3.0 port on older 2015 macbook pro 11,4?

It requires a direct connection to the computer via TB3. USB-C will not work.

Is this the current version with the detachable cable or the old version with the captive cable? The part number matches the new version.

Hello, This should be the new version with the detachable cable. The page just needs to be updated with the current images of the unit.

Will this work with a thunderbolt 2 device/ 2-3 adapter?

Hello, To use this bus-powered device on older Thunderbolt and Thunderbolt 2 computers, it has to be connected to the second Thunderbolt 3 port on another self-powered Thunderbolt 3 device. If connected directly to a host the Thunderbolt 3 to Thunderbolt 2 adapter, bus-power is insufficient. An example configuration is: Thunderbolt 2 Mac with macOS 10.13.6 or above > Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter > self-powered Thunderbolt 3 device with two TB3 ports > OWC Thunderbolt 3 10G Ethernet Adapter.
