25 pairs UTP CAT3 cable

Product description:

This series of products are manufactured according to ISO/IEC11801, EIA/TIA-568-B and China YD/T 1019-2001. Furthermore, their performance, tested by China Inspect Center For Line Transmission of MII, is superior to above standard. This series of products have passed UL authentication. Excellent data transmitting performance, low delay time, low BER (Bit Error Rate) and excellent anti electromagnetic disturbance performance are achieved by delicate cable construction and using excellent material. The maximum operating frequency is 16MHz. This series of products are mainly used in ISDN system, cabling between equipment in fast Ethernet. The standard length is 305m per box and other length can be provided according to customer’s demand.
