OPTera Packet Edge System (Resilient Packet Ring) - Ethernet
The OPTera Packet Edge System - Ethernet provides a way of delivering data
services in a wide area network (WAN). Service providers use Ethernet
interfaces (10/100/1000 Mbit/s) for WAN connections. The OPTera Packet
Edge System handles the multiplexing and virtual connections across the
optical network. OPTera Metro 3500 OPE cards provide STS-1, STS-3c, and
STS-12c Resilient Packet Ring (RPR) bandwidth.

OPTera Packet Edge is a set of distributed switch / bridge circuit packs that
support connectionless, statistically multiplexed packet traffic on a carrier
grade transport platform. The shared bandwidth OPTera Packet Edge
switching is suitable for interconnecting LANs, routers, switches, virtual
private networks, and servers on SONET topology networks for carrier and
service provider applications.

OPTera Packet Edge in Rel 12.0 supports the following circuit packs
•
4x100BT
•
4x100FX-MM
•
4x100FX-SM
•
2x1000SX (2xGigE over multimode fiber)
•
2x1000LX (2xGigE over single mode fiber)
Connectors
4x100FX circuit packs have MT-RJ connectors on the faceplate. Use 1310 nm,
single mode fiber-optic cables to interface to the 4x100FX (NTN433FA)
circuit pack. Use 850 nm, multimode fiber-optic cables to interface to the
4x100FX (NTN433EA) circuit pack. If necessary, use a patch panel to convert
between the MT-RJ connection and SC, ST, or FC connections.
