带芯片信号放大 USB3.0 公对母延长线，双层屏蔽，打印机、工业摄像头专用延长数据线
USB3.0 Male to Female Extension Cable with Chip Signal Amplifier Double Shielded Printer Camera Extension Cable
1. 规格 Spec
Q：这款有源延长线内置放大芯片有什么作用？传输速度是多少？
A：内置信号放大芯片可补偿长线信号损耗，5Gbps 全速传输，超长 20 米距离也不会降速、断连；普通无源延长线超过 5 米就容易出现信号衰减、识别不到设备。
Q: What is the function of the built-in amplifier chip? What is its transfer speed?
A: The built-in chip compensates long-distance signal loss and maintains full 5Gbps speed without speed drop or disconnection even up to 20m. Ordinary passive cables suffer severe signal attenuation beyond 5 meters and often fail to detect devices.
2. 用途 Application
Q：可以用于工业相机和直播采集卡长线布线吗？打印店打印机远距离使用稳定吗？
A：完全适配工业相机、视频采集卡，远距离直播画面无卡顿、无拖影；双层屏蔽抗干扰，打印机 10 米以上长线传输打印文件不丢数据、不卡纸。
Q: Can it be used for long wiring of industrial cameras and live capture cards? Is it stable for printers in print shops with long distance?
A: Perfect for industrial cameras and capture cards, smooth live streaming without lag or ghosting over long runs. Double shielding resists interference to ensure stable printer data transmission without missing files or paper jams over 10m.
3. 供电接口Power Port
Q：线材上额外的供电接口有什么用处？移动硬盘、工业相机供电不足可以解决吗？
A：独立辅助供电接口可外接 5V 电源补电，解决超长线材压降问题；大容量移动硬盘、高功耗工业相机不会因供电不足出现断开、识别失败。
Q: What is the extra power input port for? Can it fix insufficient power for portable hard drives and industrial cameras?
A: The auxiliary power port connects external 5V power supply to solve voltage drop on ultra-long cables. Large-capacity hard drives and high-power industrial cameras will not disconnect or fail recognition due to insufficient power.
4. 长线性能LTP
Q：现货最长支持多少米？20 米长度连接监控摄像头会出现画面卡顿吗？
A：现货最长 20 米；双层屏蔽 + 信号放大芯片双重保障，20 米布线监控画面流畅，无延迟、无马赛克、设备识别稳定。
Q: What’s the longest stock length? Will 20m cable cause video lag for surveillance cameras?
A: The maximum stock length is 20m. Double shielding plus amplifier chip guarantee smooth surveillance video without lag or mosaic, steady device recognition.
5. 交期 Lead Time
Q：少量现货订单和工程大批量带 LOGO 定制订单分别多久出货？
A：标准黑色加长款现货 48 小时内发出；改色、特殊长度、外壳丝印 LOGO 的工程批量定制订单，生产交期 4–7 个工作日。
Q: What’s the lead time for small stock orders and large engineering customized orders with logo printing?
A: Small stock orders of standard black long cables ship within 48 hours. Large engineering customized orders with color change and logo printing take 4–7 working days for production.
