Optical Ethernet - Private Line (OE-PL) and Storage applications
OPTera Metro 3500 supports efficient point-to-point Ethernet services and 
Fibre Channel Storage Area Network Extension services with the introduction 
of a new 2xGigabit Ethernet/Fibre Channel- Point-to-Point (2xGigE/FC-P2P) 
circuit pack and through the Generic Framing Procedure (GFP) and Virtual 
Concatenation (VCAT) standards. 
Note:  For information on GFP and VCAT, please refer to 
2xGigE/FC-P2P circuit pack
The 2xGigE/FC-P2P circuit pack provides cost-efficient and flexible transport 
of “leased line” type services across an OPTera Metro 3500 and/or SONET 
network. The 2xGigE/FC-P2P circuit pack also provides 2 independent LAN 
ports allowing for transport of Gigabit Ethernet or Fibre Channel signals 
across a SONET network where the traffic can be groomed, switched and 
monitored by the network.
The 2xGigE/FC-P2P circuit pack circuit pack supports the following features:
2 LAN ports independently configurable as Gigabit Ethernet or Fibre 
Channel
— each LAN port can be configured to Gigabit Ethernet, or
— each LAN port can be configured to Fibre Channel (FC100)/FICON, or 
— one LAN port configured Gigabit Ethernet and the other to Fibre 
Channel (FC100)/FICON
Ethernet Services - dedicated private point-to-point layer 1 transport
Fibre Channel Services - dedicated private point-to-point layer 1 
transparent transport (full-rate or sub-rate extended reach)
Network connectivity 
— SONET contiguous (STS-1, STS-3c, STS-12c and STS24c)
— Virtual concatenation (STS-1-nv, n = 1 through 21 or STS-3c-nv, n = 1 
through 7)
Generic Framing Procedure - Frames (GFP-F) of Ethernet frames into 
SONET
Generic Framing Procedure - Transparent (GFP-T) encapsulation of Fibre 
Channel frames into SONET
Network protection using UPSR, BLSR, and 1+1 linear
