My question is based on the info found at http://www.cisco.com/en/US/prod/collateral/modules/ps2797/ps5138/product_data_sheet09186a008007cd00_ps5455_Products_Data_Sheet.html
According to this doc if I have multimode 50 micron fiber with a modal bandwidth of 2000, I can use the XENPAK-10GB-SR for a distance of up to 300 meters. Because my fiber has this type of modal bandwidth, does this mean that this optic is my only option? Can I not use the XENPAK-10GB-LX4?
Thank in advance.
