10GBASE-ER/EW XFP specifications
The following table lists the transmitter specifications for the
10GBASE-ER/EW XFP. The reach for this XFP is up to 40 km at a
wavelength of 1550 nm. The part number of this XFP is AA1403003-E5.
For more information about the 10GBASE-EX 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.
