GigE Interface
Wavelengths are 850 nm, 1310 nm, and 1550 nm. Electrical GigE interface modules are
also supported using high-quality CAT-5e or CAT-6 cable.
SFP Specifications
The APEX1000 GigE interface requires SFP transceivers. Each of the four GbE interfaces
can accept any one of a variety of Small Form Factor Pluggable (SFP) modules, including
1000 Base SX (850 nm), 1000 Base LX (1310 nm), and 1000 Base ZX (1550 nm) fiber
based modules, or 1000 Base T Electrical based modules.
Note: The Gigabit Ethernet interfaces are full-duplex interfaces with respect to standard
L2/L3 Ethernet traffic. This includes ARP Responses to ARP Requests, ICMP Echo
Responses to ICMP Echo Requests, IGMP Joins, IGMP Host Membership Reports in
response to IGMP Queries, etc..
