Interface Module
ZXR10 8900E series core switch interface module is the line interface card. The line card
types provided include Gigabit Ethernet interface board, 10G Ethernet optical interface
board and 40G Ethernet optical interface board. All optical interfaces of line cards in
ZXR10 8900E series core switches adopt pluggable optical module, so the same line
card can support multiple kinds of transmission media and transmission distances. Some
line cards provide different types of ports, reducing the number of line cards that may be
needed in many cases, so that the use can get the largest profit with minimal investment.
Moreover, all user electrical interfaces in the line cards have cable diagnosis function.
They can detect the connection of cables at any time, make diagnosis for short circuit and
open circuit of cables and point out the position of the faults with a precision of less than
1m.
