10GBASE-ZR/ZW XFP specifications 71
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
Risk of equipment damage
To prevent damage to the optical receiver, ensure that at least 11
dB of attenuation is present between the transmit and receive
ports.
