Dwdm Xfps - Avaya 8800 Planning And Engineering

The equations and calculations used to determine maximum transmission distance for the
network example are:
Passthrough nodes = number of OADMs between first OADM and OMUX Passive loss =
OADM add + OMUX-8 demux+ (passthrough nodes*OADM passthrough loss) Implied fiber
loss = loss budget - passive loss - system margin Maximum transmission distance = implied
fiber loss/attenuation
In this case:
Passthrough nodes = 7 nodes Passive loss = 1.9 + 4.5 + (67*2.0)= 20.4 dB Implied fiber loss =
30 – 20.4 – 3 = 6.6 dB Maximum reach = (6.6 dB) / (0.25 dB/km) = 26.4 km

DWDM XFPs

The Avaya Ethernet Routing Switch 8800/8600 provides support for DWDM XFP devices on
all 10 Gigabit ports for R/RS modules (8683XLR, 8683XZR, 8612XLRS, 8634XGRS). The
Ethernet Routing Switch 8800/8600 can support 10 Gigabit, frequency multiplexed, direct
connections to Avaya CPL rings. The 8006, 8010, and 8010co chassis support the required
cooling of the DWDM XFP devices in all XFP ports in all slots.
As shown in the following table, Release 5.1 supports 20 DWDM XFPs with different Lambdas.
These are C band wavelengths, with 100 GHz spacing with both ITU frequencies (THz) and
ITU wavelenghts (nm) specified.
