40-Gig LR4 single mode fiber NA 2- 10,000 meters
1
Cat 5e cabling requires testing to 200 MHz operation and additionally for ANEXT and AELFEXT. The
maximum supported distances may be reduced depending on alien crosstalk levels. The support for untested
cable installations is best-effort.
2
Cat 6 cabling requires testing for ANEXT and AELFEXT. The maximum supported distances may be reduced
depending on alien crosstalk levels.
3
Cat 6 cabling requires TIA TSB-155A testing for 500 MHz operation and ANEXT.
4
For distances less than 20km, a 10dB attenuator must be used. For distances between 20km and 40km, a 5dB attenuator
must be used. Attenuators can be purchased from most cable vendors.
