BiDi Optics Considerations
There are several nuances to consider due to the complexity in 40Gb BiDi technology.
Because of the nature of 40Gb BiDi technology, the same BiDi optic (Full Duplex or
RX-only) cannot be used in all of the following situations. For example:
• On SPAN sessions, RX-only BiDi optics cannot be used. Full Duplex BiDi optics
must be used.
• When receiving traffic from network links, RX-only BiDi optics must be used due to
the way traffic is multiplexed over the fiber pair in 40Gb BiDi technology.
• When deploying over inline 40Gb BiDi links, Full Duplex BiDi optics must be used.
• When connecting two GigaVUE nodes through a cascade connection, Full Duplex
BiDi optics must be used for the tool port. The network port may be either Full
Duplex or RX-only BiDi optics.
• When stacking multiple GigaVUE nodes, 40Gb BiDi optics must not be used on
stack links because the 40Gb BiDi technology is not compatible with the Gigamon
stack protocol.
Transceiver Installation Instructions
Gigamon transceivers are keyed and can only be installed in one direction.
Transceivers are hot-swappable – they can be installed or removed with the power on
or off. Use the following procedures to install and remove transceivers from GigaVUE
modules.

MPORTANT
:
Always use an ESD-preventive wrist or ankle strap and ensure that it
makes good skin contact when installing or removing transceivers. The strap can be
connected to one of the following:
• ESD wrist strap connector. The GigaVUE-HC3 chassis provides a connector at
the front of the chassis for this purpose labeled with a ground symbol. The
connector is located at the front of the chassis on the lower right.
• Captive installation screws on an installed module or power supply module.
• Any unpainted surface on the chassis.
Installing Transceivers
1.
Remove the dust cap from the port and set it aside for future use.
2.
Orient the transceiver with the opening in the module and insert it into the slot.
3.
Push gently but firmly until the transceiver is seated in the slot.
4.
Close the latch on the transceiver to lock it into the slot.
