Fiber-Optic Specifications

The specification for optical fiber transmission defines two types of fiber: single-mode and multimode.
Within the single-mode category, three transmission types are defined: short reach, intermediate reach,
and long reach. Within the multimode category, only short reach is available. For information about
optical SFP modules, see the documentation for the SFP module at
http://www.cisco.com/en/US/partner/products/hw/modules/ps5455/prod_installation_guides_list.html.

A major alarm condition indicates the failure of a single fan in the fan tray; a critical alarm
indicates the failure of multiple fans. In the event that a single fan fails, the
Cisco ASR 903 Router software adjusts the fan speed to prevent excessive heat within the
chassis.
