Gigabit Interface Converters (GBICs)
The OS7-GNI-U2 module provides two Gigabit Interface
Converters (GBIC) slots. A GBIC is a Gigabit Ethernet port
module that is hot-pluggable—i.e., it can be installed or
removed while the GNI is powered on and operating without
the risk of damage to the GBIC module or the host circuitry.
When a GBIC is installed, the switch automatically gathers
basic GBIC information via the connector’s serial E2PROM
interface. This information includes the GBIC’s capabilities,
standard interfaces, manufacturer, and other information.
The following GBIC types are available for OS7-GNI-U2
modules:
•
GBIC-SX—1000BaseSX multimode fiber, supports
distances up to 550 meters; uses SC connectors
•
GBIC-LX—1000BaseLX single mode fiber, supports
distances up to 10 km; uses SC connectors
•
GBIC-LH-70—1000BaseLH long haul single mode
fiber, supports distances up to 70 km; uses SC connec-
tors
•
GBIC-C—1000BaseT copper connection, supports
distances up to 100 meters; uses one RJ-45 connector
Customers should use only Alcatel-provided GBIC modules.
Third party GBIC modules not provided by Alcatel are not
guaranteed to work properly.
Note.

Miniature Gigabit Interface Converters
(MiniGBICs)
The OS7-GNI-U12 module provides 12 MiniGBIC slots. A
MiniGBIC is a Gigabit Ethernet port module that is hot-plug-
gable—i.e., it can be installed or removed while the GNI is
powered on and operating without the risk of damage to the
MiniGBIC module or the host circuitry.
When a MiniGBIC is installed, the switch automatically gath-
ers basic MiniGBIC information via the connector’s serial
E2PROM interface. This information includes the Mini-
GBIC’s capabilities, standard interfaces, manufacturer, and
other information.
The following MiniGBIC types are available for OS7-GNI-
U12 modules:
•
MINIGBIC-SX—1000BaseSX multimode fiber,
supports distances up to 550 meters; uses LC connec-
tors
•
MINIGBIC-LX—1000BaseLX single mode fiber,
supports distances up to 10 km; uses LC connectors
•
MINIGBIC-LH-70—1000BaseLH long haul single
mode fiber, supports distances up to 70 km; uses LC
connectors
Customers should use only Alcatel-provided MiniGBIC
modules. Third party MiniGBIC modules not provided by
Alcatel are not guaranteed to work properly.
