OPTera Packet Edge System 4x100FX circuit pack
(NTN433EA, FA)
The OPTera Packet Edge System circuit pack works as a distributed switch and
bridge to connect Ethernet LANs on a high-speed SONET network. OPTera
Metro 3500 supports the singlemode and multimode 4x100FX circuit packs.
The OPTera Packet Edge System 4x100FX circuit pack allows a fiber LAN
tributary interface to connect directly to the circuit pack faceplate. The
4x100FX circuit pack supports STS-1, STS-3c, and STS-12c bandwidth rates.
Equipping rules
The OPTera Metro 3500 shelf supports eight OPTera Packet Edge System
4x100FX circuit packs in slots 3 through 10. 4x100FX circuit packs only
operate in an unprotected mode. Users can install only 2x100BT-P2P,
4x100BT, 4x100FX, and 2xGigE/FC-P2P circuit packs in adjacent slots.
If a 2x100BT-P2P, 4x100FX, 4x100BT or 2xGigE/FC-P2P circuit pack is
inserted into an odd slot (n
odd
), then you can only insert one of the following
circuit packs into the even slot (n
odd
+1):
• 2x100BT-P2P
• 4x100BT
• 4x100FX
• 2xGigE/FC-P2P
If a 2x100BT-P2P, 4x100FX, 4x100BT or 2xGigE/FC-P2P circuit pack is
inserted into an even slot (n

• 2x100BT-P2P
• 4x100BT
• 4x100FX
• 2xGigE/FC-P2P
