10GBASE-ZR/ZW XFP specifications 79
Examples of an OFF transmitter are: no power supplied to the PDM, laser
shutdown for safety conditions, activation of a PMD_global_transmit_disable
or other optional transmitter shut down conditions.
10GBASE-ZR/ZW XFP specifications
The following table lists the transmit specifications for the 10GBASE-ZR/ZW
XFP. The reach is up to 80 km at a wavelength of 1550 nm. The part
number of this XFP is AA1403006-E5.
For more information about the 10GBASE-ZX XFP, including test and
measurement information and more specifications, see the IEEE 802.3ae
standard.
ATTENTION
You can configure the XFP to operate in either LAN (Ethernet) or WAN (SONET)
mode, depending on the module (8683XLR is a LAN-only module, and 8683XZR
is a LAN/ WAN module). Model numbers ending in R denote a LAN interface;
model numbers ending in W denote a WAN interface.
CAUTION
To prevent damage to the optical receiver, ensure that at least 11
dB of attenuation is present between the transmit and receive
ports.
