III. Interface
1) 1000 Mbps Ethernet interface
The ERPU provides three 10/100/1000 Mbps Ethernet interfaces that each
accommodate an RJ-45 connector and a small form-factor pluggable (SFP) module
respectively for electrical and optical connections. But you can use only one connection
at a time.
Five types of 1000Base-FX SFP transceiver modules are available: multi-mode
short-haul (850 nm), single mode medium-haul (1310 nm), single mode long-haul
(1310 nm), single mode long-haul (1550 nm), and single mode ultra-long haul (1550
nm). They all provide LC interfaces and are hot swappable.
The following table gives the features of the ERPU GE interfaces:
