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.

1. Both ends of an individual fibre must use GBICs of the same wavelength.
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:
