Introduction to Huaqiangsheng Electronics: The characteristics of a 10G network transformer are good or bad, and the stability of the final product network transmission depends most importantly on the high-frequency parameters of the product. The final decisive influence comes from the product line package. After years of production practice and continuous research and development investment, the production methods of 10G line packages have continuously changed, developing into various schools and schemes. In addition to the double hole ring scheme that the company has recorded a long time ago (see previous articles), it has also gradually developed into the following two increasingly simple 10G line package schemes. This is a brief record for archival purposes

20 years from now, the line package plan for 10 Gigabit network transformers,

Option 1: 8-line large loop and 4-line small loop solution

Plan description: This plan is the PuSi 10G plan, and H7108/7008/7109 all use this plan

1、 The earliest 10 Gigabit Ethernet card designed by PuSi corresponds to the product 7008 (corresponding to our company's G82408S), with an 8-wire process and a wire diameter of 0.08, and weak POE capability. The process is complicated and the unit price is relatively expensive, but the network parameters are good, suitable for use with 10 Gigabit network cards.

2、 In order to increase the POE function of the product, 7108 (corresponding to our company's G82418S) was developed, using a 4-wire process with a wire diameter of 0.127 and a POE of 600MA, resulting in a loss of some high-frequency network parameters. Mainly suitable for use with VALANS extenders, with advantages such as lower cost, increased POE, and availability of network cards. Compared to 7008, it is better, but 7008 has been discontinued

3、 By retaining relatively good network parameters, adopting an 8-wire process with a wire diameter of 0.08, and adopting a more suitable line structure for POE, 7109 was developed POE can exceed 30W 500MA

Option 2, 6-line large ring, 3-line small ring scheme

Scheme description: This scheme is a BEL scheme

Comparatively speaking, Scheme 1 has better characteristics than Scheme 2, reflected in the IR value of 400-500M

The coil structure of 2.5G network transformer

G82408S-PY (YY PuSi scheme) 7.5 including tax (PuSi 10Mbps cable package, tapped adhesive)

G82408-Y (YY self plan) 6.8 including tax (10000 MW four wire package, domestic wire package process)

G82408S-W (WP) 7.8 including tax (original factory, non white wire, tap without glue)

G82408S-PW (PuSi WP) 9.8 including tax (original factory, white wire, tap without glue)

7019 is mainly used with Valens as an extender, matrix~

7019 has better network parameters than 7108 and can be used in network communication, extenders, and matrices, but it is more expensive than 7108

Eight thread threading! 7108 chose thick thread for POE and 4 thread threading for cost

Sacrificing network parameters

Different magnetic cores, 7019, 8 wires passing through small rings, 7108, 4 wires passing through small rings,

Look at the application on the client side, 7108 is enough for it. If the client uses a matrix to make a 10G network card, it will be 7019

  5G spectrum range and allocation

  5G频谱分配5G最大的载波带宽会达到400MHz甚至更高。目前频率带宽比较紧张，5G不得不使用高频进行通信。5G频谱大致分为两个范围频率分类 对应频率范围FR1 450MHz - 6000MHzFR2 24250MHZ - 52600MHZ。FR1：sub6G 频段，也就是常说的低频频段，是5G的主用频段，其中在3G以下的频段称之为sub3G , 其余的频段是c-band。。FR2：毫米波，高频频

  Introducing the production method of 10G Ethernet transformer G82418S

  互联网用的以太网变压器正常的一般都是100/1000MHz的速率传输信号，也就是传说中的百兆千兆网络变压器。正常的100/1000MHz传输速率的以太网变压器参数IL的范围在-1.0dBMAX@1-100MHz；参数RL的范围在-18dBMIN~-10dBMIN@1-100MHz。市场变化日新月异，常规的100/1000MHz速率传输的以太网变压器已不能满足互联网提速的需求。
