Chapter 1 About the ASA 5500-X

SFP Modules

The ASA uses field-replaceable small form-factor pluggable (SFP) modules to establish Gigabit

Ethernet connections. Table 1-1 lists the supported SFP modules.

Use only Cisco-certified SFP modules on the ASA. Each SFP module has an internal serial EEPROM

that is encoded with security information. This encoding allows Cisco to identify and validate that the

SFP module meets the requirements for the ASA.

All SFP ports require cables with LC-type connectors. Minimum cable distance for all SFPs listed (both

SMF and MMF) is 2 m (6.5 feet); cables must not exceed specified cable lengths for reliable

communications. Table 1-2 lists the fiber-optic cable requirements.
