陰特兒（Intel）1000Base-T 設計指導書（Design Guide）：

, P/ e. o8 E. c* PMagnetics modules for 1000 BASE-T Ethernet are similar to those designed solely for 10/100　Mbps, except that there are four differential signal pairs instead of two. Use the following guidelines to verify specific electrical parameters:

• Verify that the rated return loss is 19 dB or greater from 2 MHz through 30 MHz for 100BASE-TX.
• Verify that the rated return loss is 12 dB or greater at 80 MHz for 100 BASE-TX (the
• specification requires greater than or equal to 10 dB). Verify that the rated return loss is 10 dB or greater at 100 MHz for 1000 BASE-TX (the specification requires greater than or equal to 8 dB).
• Verify that the insertion loss is less than 1.0 dB at 100 kHz through 80 MHz for 100 BASETX.
• Verify that the insertion loss is less than 1.4 dB at 100 kHz through 100 MHz for 1000 BASET.
• Verify at least 30 dB of crosstalk isolation between adjacent channels (through 150 MHz).
• Verify high voltage isolation to 15000 Vrms
• Transmitter OCL should be greater than or equal to 350 μH with 8 mA DC bias.
