1.Cable distances are based on fiber loss. Additional factors, such as the number of splices and the optical quality of the fiber, can affect cabling distances.

2.Refer to the product bulletin for the usage of mode conditioning patch cords in 1000BASE and 10GBASE Ethernet laser-based transmissions at this URL: http://www.cisco.com/en/US/prod/collateral/modules/ps5455/product_bulletin_c25-530836.html

3.ITU-T G.652 SMF as specified by the IEEE 802.3z standard.

4.1000BASE-ZX SFP modules can reach up to 62 miles (100 km) by using dispersion-shifted SMF or low-attenuation SMF; the actual distance depends on the fiber quality, the number of splices, and the connectors.

Table B-9lists the fiber loss budgets for the 1-GB SFP transceivers.
