Use the bnc dual-connector coaxial cable form as a starting point and confirm these design points against drawings and the actual equipment.以BNC双接头同轴连接线的结构形式为起点，结合图纸和实际设备确认以下设计要点。
Signal path信号路径
Define signal type, pair allocation, shield continuity and termination as well as the connector shape. Establish transmission performance from the actual cable, length and system validation.在接口外形之外确认信号类型、线对分配、屏蔽连续性和端接方法；传输能力应按实际线材、长度及整机验证结果确定。
Conductor and insulation selection导体与绝缘选配
Select conductors and insulation from circuit loads, diameter limits, bending and exposure. A material name does not replace ratings or validation results.从电路负载、外径限制、弯曲方式与环境条件选择导体和绝缘体系；材料名称不应直接代替额定参数或验证结果。
Interface and function review接口与功能确认

PRODUCT QUESTIONS产品问答
Product & customization questions产品与定制常见问题
Can an RF cable be selected from connector photos?可以只凭连接器照片选择 RF 电缆吗？
No. Photos help identify a family, but exact interface, gender, polarity, impedance, frequency, cable type, length and environment still require drawings, part numbers or equipment data.不可以。照片只有助于识别系列，精确界面、性别、极性、阻抗、频率、线缆类型、长度与环境仍需图纸、型号或设备资料。
What is the difference between 50-ohm and 75-ohm coax?50Ω 与 75Ω 同轴线有什么区别？
They use different conductor and dielectric geometry and serve different systems. Fifty ohms is common in RF and test equipment; 75 ohms is common in video and broadcast. The cable and both interfaces must match the equipment impedance.它们使用不同导体与介质几何，服务于不同系统。50Ω 常见于 RF 与测试设备，75Ω 常见于视频与广播；线缆和两端界面都必须匹配设备阻抗。
Does a higher-frequency connector guarantee the complete cable rating?使用更高频率连接器就能保证整条电缆频率吗？
No. The usable assembly band is limited by the cable, both connectors, termination quality, transitions, length, routing and acceptance limits. The complete assembly must be reviewed and, where required, measured.不能。组件可用频段受线缆、两端连接器、端接质量、过渡、长度、路由与接收限值共同限制，需要审核完整组件，必要时进行测量。
