Anyone who has seen the sci-fi movie Top Player should know that people in the movie call the virtual reality world "oasis", while in reality, Internet technology giants call it the meta universe. With the maturity of underlying technology, hardware and software have reached the threshold. In 2021, the concept of "meta universe" will become popular. In fact, Tencent, Microsoft, ByteDance, Facebook and other giants have already taken action.
Earlier, Facebook CEO Mark Zuckerberg proposed that Facebook should be known as a "meta universe company" and hoped to complete this strategic change in the next five years. Recently, the charging head network has obtained the optical fiber fast charging CC line product launched by Facebook based on the concept of "meta universe".
This cable is designed separately with optical fiber and copper cable. In addition to supporting 60W PD fast charging, it also supports high-speed data transmission and networking functions. In addition, the cable is launched based on the concept of "meta universe", which is specially designed for VR enthusiasts. Therefore, it is 5 meters long, meeting users' VR game needs. The charging head network will disassemble this cable in detail to see how it is made.

The cables are tied and arranged with magic straps, which gives a direct impression of both weight and length.
Both ends of the cable are designed with straight ends and elbows, and anti bending treatment is made. The wire head shell is frosted for easy plugging.
The center of the straight head housing is designed with a bright face ring.
The other end is designed with an elbow. Connecting VR equipment can reduce the bending and protect the cable.

The thread body is strong and flexible, and the overall skin is smooth without burrs.
The measured length of the whole cable is about 5 meters, which is also designed for VR enthusiasts.
The diameter of wire body is 4.5mm.
The weight is about 218g.
Finally, using ChargerLAB POWER － Z KM001C, it is measured that the cable is equipped with an E-Marker chip and an active cable. It shows that the power transmission capacity is 20V3A, supports a maximum 60W PD fast charging, and the transmission specification is USB3.2 Gen1, which is commonly known as USB3.0, 5Gbps.
2, Disassembly of Facebook Oculus VR dedicated data cable
Cut the straight plastic housing apart.
The internal small plates are reinforced and protected with hard sealing glue and steel sleeves, and the center of the steel sleeves is pasted with heat dissipation copper foil.
Dismantle the steel sleeve, stick insulating tape on the inner side, and hollow out the corresponding copper foil area. The center of the small board is pasted with copper foil, the periphery is fixed with glue injection, and the wire core is also molded into a whole for protection.
Disassembly summary of charging head network
Although this is a product launched by Facebook specifically for the VR field, it can also be used for laptop, tablet, mobile phone and other devices in terms of performance, and one end is designed with an elbow for better user experience in connecting devices. The cable length is up to 5 meters, meeting VR users' requirements for long cables.
After disassembling the charging head network, it is found that the internal design of the wire heads at both ends is basically the same, but the difference is that the straight end is additionally equipped with an E-MARKER chip. In addition, both ends are equipped with STM8S003 single-chip microcomputer control terminal function. In addition, there are chips that convert USB-C signals into electrical signals, which are transmitted through optical fiber connection. The chips are also covered with plastic shells, metal sheets and copper foils for protection and heat dissipation.
The chip, small board and wire core inside the whole terminal are protected by injection molding, and the outer steel sleeve is reinforced by spot welding, so the design is reasonable and protective. In addition, when cutting the wire body, it is found that there are a large number of Keff stay wires mixed inside, so the cable is very flexible and tensile.
