我用PSE 选用LTC4266A 输出功率选用90W， PD接收选用LT4275A. 通过CAT5E 相连， 请问一下，这类网线最长距离可支持多少米，主要会受到哪些条件的制约。 谢谢
For the LTPoE++ 90W power level, the recommended cable is CAT-5E or better, 100m, and a cable bundle maximum of 25 cables. LTPoE++ 38.7W, 52.7W, and 70W power levels allow for up to 100m cable bundle size.
我需要的传输距离为200M ,可否有什么方法增加距离。 还想问一下，传输距离是否同工作电压有关。谢谢
A 200m distance is non-standard for PoE. Items to consider for 200m power transmission:
1) Cable type and resistance.
2) Source voltage and safety requirements.
3) Input voltage at end device and load.
4) Data transmission distance limits.
