Gigabit Interface Converters (GBICs)
The AT-SB4441 line card provides ports for eight GBICs. These are small
hot-swappable plug-in transceivers. By selecting the appropriate GBIC type,
you can match your SwitchBlade ports to their appropriate network interface.
RJ-45 copper, SC and LC fibre GBICs are currently available.
GBIC 1000BASE-T Auto-Negotiation
The 1000BASE-T GBICs operating in the AT-SB4441 line card will provide only
1000 Mbps full-duplex connections. Although these GBICs will participate in
auto-negotiation processes, they will only advertise 1000 Mbps. Half duplex,
10BASE-T, and 100BASE-TX modes are not supported.
While 1000BASE-T GBICs will auto-negotiate at the copper Ethernet level, the
ports will behave as if in fixed 1000 Mbps full-duplex mode. This is because the
SERDES connection used by GBIC ports makes the auto-negotiation invisible
to the switch, and so prevents a successful link negotiation.
The following Allied Telesis GBIC transceivers can be ordered from your
authorisedAllied Telesis reseller.
Small Form Factor Pluggables (SFPs)
The AT-SB4442 line card provides ports for 24 SFPs. SFPs are miniature
hot-swappable plug-in transceivers. By selecting the appropriate SFP type, 1
Gbps ports can be matched to the appropriate network interface, RJ-45 copper
or LC fibre. The following Allied Telesis SFP transceivers can be ordered from
your Allied Telesis reseller:
