1. Multimode fiber (MMF) only.
2. Dispersion-shifted single-mode fiber-optic cable.
The 1000BASE-ZX SFP modules provide an optical power budget of 21.5 dB. You should measure your
Note
cable plant with an optical loss test set to verify that the optical loss of the cable plant (including
connectors and splices) is less than or equal to 21.5 dB. The optical loss measurement must be performed
with a 1550-nm light source.
