Last month, ChargerLAB got a 1.8m Apple Thunderbolt 4 pro cable.
And the 3m wasn’t available at that time.
But recently, we found it was available on Apple’s official website.
And the price has reached $159.
So, we ordered it immediately,
and now, here is it.
The packaging is almost the same as the 1.8m cable.
You can click the upper right corner to take a look.
The model is different.
A2162.
Open the box. It contains the cable and manuals inside.
This might be the longest Thunderbolt 4 cable in the industry.
The connector is pretty long with the “Thunderbolt” logo on it.
And here is a tiny “Apple” logo in here.
The internal 24 pins are plated with gold.
You can pause to see what they correspond to.
And there is still no protective sleeve between the cable and the connector.
It’s very thick and adopts black braided design that coils without tangling.
The length of this cable is 2.94m (9’ 7.75”).
A little bit shorter.
And the diameter is 5mm (0.2 inches).
The weight is about 164g (5.78 oz).
Almost the weight of an iPhone.
The ChargerLAB POWER-Z KM001C
shows it’s an active cable and can support 20V5A 100W, and up to 40Gbps.
Use it to charge the MacBook Pro 16”.
The power is about 95W.
And then, put it between the Samsung 970EVO and MacBook Pro 16”.
Disk Speed ​​Test shows it can reach 1400MB/s writing and 2800MB/s reading.
Firstly, let’s cut it off.
We can see two layers of wires.
The outer layer is composed of ten coaxial cables.
And the six wires of the inner layer are used for positive power supply.
Remove the woven layer. And we can see the black TPE, pretty smooth.
Cut off the TPE, and the shielding layer is under it.
And then, another tin foil layer for shielding.
This is the third layer of shielding.
And we can finally see the colored wires inside.
They can be used for data transmission and power supply, separately.
Let’s separate and introduce them one by one.
Those five red wires and a purple wire are used for positive power supply.
And it’s made of tinned copper wire.
The red, golden, green, and blue wires are differential signal wires and adopt coaxial design.
And the first layer is plastic insulating layer,
and the copper foil is under it.
The most internal wires are plated with silver and wrapped with pure copper shielding plated with silver.
Those two red wires with orange plastic are used for USB2.0 transmission.
This is another red wire with white plastic.
And then, the blue wire is CC wire. The yellow one is Vconn wire.
And the black one is SBU wire.
Finally, there’re some bare negative wires.
After analyzing the cable, let’s take apart the connector.
Just like the 1.8m, the PCB is protected by brass sleeve.
And there’re two circles of dense solder joints on it, which can fix the connector and the junction.
The C18R010 is in here.
EC16H2 is on the other side.
After removing the brass sleeve, we can see the small PCB inside.
There’re four shield covers under the largest chip to reduce the interference.
After removing it, we found four pairs of differential signal wires we’ve
mentioned are soldered side by side.
And then, let’s take a closer look at the inside of the connector.
There’re a total of 24 pins. And the junction is protected by glue.
Each pin is plated with gold, which can be more durable.
You can pause to see what they correspond to.
The largest one is Intel Thunderbolt ReTimer chip. Model is JHL7040.
It’s used for signal reconstruction and can reduce signal jitter.
And it also might be the reason why it can be 3m.
This is crystal oscillator, marked with 25000.
Flip to the back. It’s equipped with buck circuit and E-marker chip.
Another large chip is from Infineon CYPDC1186.
It even integrates an Arm processor and flash inside, just for a cable.
That’s insane.
This is step-down inductor.
This one comes from MPS, marked with HU.
We presumed it’s a step-down chip.
And finally, Here is the ON Semiconductor diode.
Both ends are exactly the same.
Well, that’s all components of this 3m Apple Thunderbolt 4 cable.
Most of its internal components are similar to the 1.8m.
But those six positive power supply wires are slightly thicker
to reduce the data loss over long distances.
And the USB 2.0 transmission wires have changed to red instead of green.
If you’re the person who really needs this cable, $159 won’t be very expensive.
But for most people who don’t need it, there’re lots of substitutes for you to choose from.
OK, that’s all for today’s video.
