Optical power considerations
When you connect the switch to collocated equipment, such as the OPTera Metro 5200, ensure that
enough optical attenuation exists to avoid overloading the receivers of each device. Typically, this is
approximately three to five decibels (dB). However, you do not have to attenuate the signal when
using the 10GE WAN module in an optically-protected configuration with two OM5200 10G
transponders. In such a configuration, use an optical splitter that provides a few dB of loss. Do not
attenuate the signal to less than the receiver sensitivity of the OM5200 10G transponder
(approximately –11 dBm). Other WAN equipment, such as the Cross Connect DX and the Long
Haul 1600G, have transmitters that allow you to change the transmitter power level. By default, they
are typically set to –10 dBm, thus requiring no additional receiver attenuation for the 10GE WAN
module. For specifications for the 10 GbE modules, see Avaya Ethernet Routing Switch 8800/8600

10 GbE WAN module optical interoperability
Although the 10 GbE WAN module uses a 1310 nanometer (nm) transmitter, it uses a wideband
receiver that allows it to interwork with products using 1550 nm 10 Gigabit interfaces. Such products
include the Cross Connect DX and the Long Haul 1600G. The Avaya OM5200 10G optical
transponder utilizes a 1310 nm client-side transmitter.
1000BASE-X and 10GBASE-X reach
Various SFP (1 Gbit/s), SFP+(10Gbit/s), and XFP (10 Gbit/s) transceivers can be used to attain
different line rates and reaches. The following table shows typical reach attainable with optical
devices. To calculate the reach for your particular fiber link, see
