ONS 15454 MSTP TransponderMuxponder Interfaces
ONS 15454 MSTP Transponder/Muxponder InterfacesClient access to ONS 15454 MSTP wavelength channels is accomplished using transponders and muxponders. These interface units function as wavelength converters, in that they convert client interface signalsoperating typically at 1310 nmto an ITU-T DWDM wavelength channel within the ONS 15454 MSTP C-band spectrum. The muxponder interfaces perform the additional function of aggregating multiple client signals into a single DWDM channel. 2.5G Multirate TransponderThe 2.5-Gbps multirate transponder (MR-L1-xx.x, MRP-L1-xx.x) provides a flexible, multirate interface for customer signals. The customer input port can operate transparently in 2R (regenerate, reamplify) or 3R (regenerate, retime, reamplify) mode, depending upon the type of signal it processes. Additionally, the 2.5-Gbps multirate transponder provides a 3R+ mode of operation. In this operating mode, the incoming client signal is mapped into an ITU-T G.709 digital wrapper for DWDM transport. The G.709 digital wrapper provides SONET/Synchronous Digital Hierarchy (SDH)like overhead functions for improved DWDM signal performance monitoring. It also facilitates the employment of forward error correction (FEC) to enhance the optical line reach of the DWDM trunk signal. The client port can be provisioned to accept an incoming signal ranging from 8 Mbps to a full 2.5 Gbps SONET/SDH rate. Client port access is accomplished using a wide variety of small form factor pluggable (SFP) interfaces. These SFP interfaces vary depending upon whether customer signals are carrying native SONET/SDH signals, Ethernet, or storage protocols, such as Enterprise Systems Connection (ESCON) or Fibre Channel (FC), and so on. The DWDM trunk-facing port is software tunable within 400 GHz, covering four ITU-T channels on the 100 GHz grid or eight ITU-T channels on the 50 GHz grid. The DWDM trunk is formatted as a SONET/SDH, long-reach OC-48/STM-16 signal. Eight 2.5-Gbps multirate transponders are available to cover the ONS 15454 MSTP C-band spectrum. The 2.5-Gbps multirate transponder can operate in the ONS 15454 MSTP shelf assembly as a single, unprotected unit, or the DWDM trunk can be protected using an on-board passive optical splitter. Thus, two product codes are available for the 2.5-Gbps multirate transponder: one for unprotected DWDM trunk operation and another for protected DWDM trunk operation. Optionally, a Y-cable can be used to split the output of a customer's signal and distribute each output to two discreet, unprotected 2.5-Gbps multirate transponders installed in the ONS 15454 MSTP chassis to accomplish DWDM trunk protection. The 2.5-Gbps multirate transponder can operate in Slots 16 or 1217 of the ONS 15454 MSTP shelf assembly. 10G Multirate TransponderThe 10-Gbps multirate transponder (10E-L1-xx.x) provides a flexible, multirate, multiprotocol 10-Gbps interface for customer signals. The customer input port can operate transparently or can be provisioned to terminate SONET/SDH line data communications channels (LDCC). The interface card supports ITU-T G.709 digital wrapper for 10-Gbps Ethernet and OC-192/STM-64. Enhanced forward error correction (E-FEC) for DWDM transport is also available. The client port provides a 1310-nm short-reach interface that accepts a 10-Gbps Ethernet WAN/LAN PHY signal, 10-Gbps FC input, or an OC-192/STM-64 SONET/SDH signal. Client port access is accomplished using a 10-Gbps small form factor pluggable (XFP) interface. Presently, the XFP receptacle supports only short-reach, 1310-nm interfaces for all supported protocols. The DWDM trunk-facing port is software tunable within 400 GHz, covering four ITU-T channels on the 100 GHz grid or eight ITU-T channels on the 50 GHz grid. The DWDM trunk is formatted as a SONET/SDH, long-reach OC-192/STM-64 signal, 10-Gbps WAN/LAN PHY, or 10-Gbps FC. Eight 10-Gbps multirate transponders are available to cover the ONS 15454 MSTP C-band spectrum. The 10-Gbps multirate transponder can operate in the ONS 15454 MSTP shelf assembly as a single, unprotected unit, or can be deployed in pairs, where client port protection is provided using the customer-attached 10-Gbps equipment. Optionally, a Y-cable can be used to split the output of a customer's signal and distribute each output to two discreet, unprotected 10-Gbps multirate transponders installed in the ONS 15454 MSTP chassis to accomplish DWDM trunk protection. The 10-Gbps multirate transponder can operate in Slots 16 or 1217 of the ONS 15454 MSTP shelf assembly. 4x2.5G Enhanced MuxponderThe 4x2.5-Gbps enhanced muxponder (10ME-xx.x) accepts four OC-48/STM-16 client signals and multiplexes them into a single 10-Gbps, ITU-T 100 GHzspaced DWDM channel. The interface card can be provisioned to operate transparently or can terminate client SONET/SDH line and section overhead bytes. In transparent mode, client endpoints connected across the DWDM network can communicate using the SONET/SDH section/multiplex data communications channel (SDCC/MSDCC). This facilitates the support of end-to-end client 1+1 automatic protection switching (APS) or bidirectional line switch ring (BLSR)/Multiplex Section Shared Protection (MS-SPR). Additionally, end-to-end client SONET/SDH unidirectional path-switched ring (UPSR)/Subnetwork Connection Protection (SNCP) is supported in both transparent and terminating port modes. The interface card supports ITU-T G.709 digital wrapper and enhanced forward error correction (E-FEC) for DWDM transport. Client port access is accomplished using a wide array of SFP interfaces. SFP interfaces are available to support short-reach and intermediate-reach OC-48/STM-16 client inputs. In addition, DWDM SFP modules can be supported on the client interfaces. The DWDM trunk-facing port is software tunable within 400 GHz, covering four ITU-T channels on the 100 GHz grid or eight ITU-T channels on the 50 GHz grid. The DWDM trunk is formatted as a 10-Gbps, G.709 digital wrapper, long-haul DWDM wavelength channel. Eight 4x2.5-Gbps enhanced muxponders are available to cover the ONS 15454 MSTP C-band spectrum. The 4x2.5-Gbps enhanced muxponder can operate in the ONS 15454 MSTP shelf assembly as a single, unprotected unit, or can be deployed in pairs, where client port protection is provided using SONET/SDH standard point-to-point or ring protocols. Optionally, client ports can be protected using a Y-cable that splits a customer's input signal and distributes each output to two separate muxponder interfaces. The 4x2.5-Gbps enhanced muxponder can operate in Slots 16 or 1217 of the ONS 15454 MSTP shelf assembly. 2.5G Multiservice Aggregation CardThe 2.5-Gbps multiservice aggregation card (DM-L1-xx.x, DMP-L1-xx.x) multiplexes up to eight client input signals into a single 2.5-Gbps ITU-T DWDM wavelength channel. Client port access is accomplished using a wide variety of SFP interfaces. These SFP interfaces vary depending upon whether customer signals are carrying Ethernet or storage protocols, such as fiber connection (FICON) or FC, and so on. Presently, 850-nm/1310-nm multimode/single-mode SFP interfaces are supported for Gigabit Ethernet (GigE), 1- or 2-Gbps FC, and 1- or 2-Gbps FICON. The DWDM trunk-facing port is software tunable within 400 GHz, covering four ITU-T channels on the 100 GHz grid or eight ITU-T channels on the 50 GHz grid. The DWDM trunk is formatted as a SONET/SDH, long-reach OC-48/STM-16 signal. Therefore, two GigE, 1-Gbps FC/FICON multiplexed ports are supported. Correspondingly, one 2-Gbps FC/FICON multiplexed signal is also supported. Eight 2.5-Gbps multiservice aggregation cards are available to cover the ONS 15454 MSTP C-band spectrum. The 2.5-Gbps multiservice aggregation card can operate in the ONS 15454 MSTP shelf assembly as a single, unprotected unit, or the DWDM trunk can be protected using an on-board passive optical splitter. Thus, two product codes are available for the 2.5-Gbps aggregation card: one for unprotected DWDM trunk operation and the other for protected DWDM trunk operation. Optionally, a Y-cable can be used to split the output of a customer's signal and distribute each output to two discreet, unprotected 2.5-Gbps multiservice aggregation cards installed in the ONS 15454 MSTP chassis to accomplish DWDM trunk protection. The 2.5-Gbps multiservice aggregation card can operate in Slots 16 or 1217 of the ONS 15454 MSTP shelf assembly. Table 9-7 details the service mix supported using the transponder and muxponder interfaces for the ONS 15454 MSTP shelf assembly.
