Notice! This is a project that a Taobao store owner claims is worth 2,722 yuan (manual dog head)             

This project is based on RTL8213B main control + SGMII (1.25Gbps) single-mode single-fiber Gigabit optical-to-electrical converter, four-layer board design, TYPE-c power supply, and supports USB power output for convenience.

Can be used with this switch: https://oshwhub.com/Kirito/shi-gong-zhong-V2.0shi-yong-5kou

RTL8213B-CG is a QFN40 high-performance media converter with low-power integrated single-port functionality and supports the Gigabit physical layer of 1000Base-T, 100Base-TX and 10Base-T.

The embedded packet storage SRAM in RTL8213B has excellent memory management technology to efficiently utilize memory space. The RTL8213B combines a 2048-entry lookup table with a 4-way XOR hashing algorithm for address search and learning. The table provides read/write access from an I2C-like serial interface, or from a Media Independent Interface Management (MIIM) interface. One of each of these entries can be configured as a static entry. The normal aging time is between 200 and 400 seconds. 16 filtering databases are used to provide independent VLAN learning and shared VLAN learning (IVL/SVL) functions.

 Embedded single-port 10/100/1000Base-T PHY

 Each port supports full duplex 10/100/1000M connectivity (half duplex only supported in 10/100M mode)

 Supports IEEE 802.1Q VLAN & IEEE 802.1ad Stacking VLAN

 Supports IVL, SVL, and IVL/SVL

∎ Supports IEEE 802.1x Access Control Protocol

 Supports Auto protection from Denial-of-Service attacks

Internal structure:

To ensure stable operation, please use a 5V2A power supply, maintain good heat dissipation, and keep the operating temperature high.

The acrylic shell is being modeled and produced. . .

Welding finished product and use:

The V1.0 version has been successfully verified for the first time and is currently undergoing a one-month stability test. There are currently basically no bugs and the V1.0 version is ready for proofing.

The optical module is single-mode single-fiber Gigabit. This store will be cheaper and of better quality:

See the video for the actual usage test. It can run up to 1000M.

You’ve seen this, why don’t you leave without giving me a thumbs up? (*╹▽╹*)

===================Separating line========================

Update: Redraw the PCB, optimize the routing, reduce the area, the version has been upgraded to V1.1, and the test has passed.

The V1.1 version is not open source, it is only for optimization and area reduction, and there is no difference in functions. In order to support the author and subsidize his family, please friends in need choose to buy it, thank you.
