Cables

The Cisco NAM 2204 appliance uses two types of fiber optical cables depending upon the SFP module you use. For short range SFPs, the appliance uses multi-mode (MM) fiber optical cables. For long range SFPs, the appliance uses single-mode (SM) fiber optical cables.

Table B-1, SFP Port Cabling Specifications, provides SFP cabling specifications for the Cisco NAM 2204 appliance.

SFP Module	Wavelength	Fiber Type	Core Size (micron)	Mondal Bandwidth (Mhz *km	Maximum Cable Distance
GLC-SX-SM	850 nm	MMF	62.5	160	722 ft (220 m)
			62.5	200	902 ft (275 m)
			50.0	400	1640 ft (500 m)
			50.0	500	1804 ft (550 m)

The Cisco 2204-SFP appliance supports the following Cisco SFPs (or industry standard equivalent): Besides the Cisco SFPs, the following SFPs have been tested and are supported in the Cisco 2204-SFP appliance:

•GLC-T—1000BASE-T SFP

•GLC-SX-MM—1 GE SFP, LC connector, SX transceiver

•GLC-LH-SM—1 GE SFP, LC connector, LX/LH transceiver

Tap Devices

You can use optical tap devices with the Cisco 2204-SFP appliance and copper tap devices with the Cisco 2204-RJ45 appliance.

Breakout Mode Configuration

To use breakout mode configuration, use an optical tap to split the Tx and Rx signals of two connected devices so the NAM appliance receives the Tx of both devices to observe the transmitted output of each device.

There are two breakout mode configurations:

•Tx of one direction of the monitored data traffic is replicated on Tx of one breakout port and Tx of the other direction of the monitored data traffic is replicated on Tx of the other breakout port.

This case provides two output replicated ports: one for Tx in one direction and one for Tx of the other direction. Each replicated port is an input to a different monitoring port of the appliance to monitor both directions of traffic.

•Tx of one direction of the monitored data traffic is replicated in one Tx connection of the breakout port and Tx of the other direction of the monitored data traffic is replicated on the other Tx connection of the same breakout port.

This case provides only one replicated port which has Tx of both directions . This case requires you to split the connectors of one fiber optical cable and put one connector into one appliance monitoring port and put the other connector into a different appliance monitoring port.
