The Cisco® ONS 15454 Multiservice Transport Platform (MSTP) supports the Cisco ONS 15454 10-Port 10 Gbps Line Card, which simplifies the integration and transport of 10-Gbps interfaces and services into enterprise or service provider optical networks (Figure 1).
Release 9.6 of the Cisco ONS 15454 MSTP extends the total data transport capacity by a factor of three, allowing Dense Wavelength-Division Multiplexing (DWDM) transmission of up to 9.6 Tbps (96 wavelengths at 100 Gbps each) in the C-band.
Figure 1. Cisco ONS 15454 10-Port 10 Gbps Line Card
Challenge and Solution
The bandwidth carried on core and metropolitan DWDM networks is growing exponentially, while operators' revenues are not keeping pace. The Cisco ONS 15454 100-Gbps solution can dramatically lower the cost-to-carry bandwidth, helping to maintain and improve customers' profitability. Internet growth is still exponential, mainly due to demand for next-generation services such as quadruple play (data, voice, video, and mobility), video distribution, Internet Protocol Television (IPTV), and other high-bandwidth services.
Due to advanced modulation techniques, the ability to transmit 100-Gbps wavelengths on existing or new DWDM systems maximizes return on investment by increasing the overall capacity per fiber pair without impacting the unregenerated transmission distance supported by the system. Scaling from 10 Gbps to 40 Gbps and now 100 Gbps multiplies by a factor of 10 the bandwidth that can be transported over existing fiber networks.
New coherent polarization-multiplexing differential quadrature phase shift keying (CP-DQPSK) modulation supports 9.6 Tbps capacity transmission over Ultra-Long-Haul (ULH) networks, up to 3000 km of unregenerated optical spans.
The Cisco ONS 15454 10-Port 10 Gbps Line Card is designed to provide up to 10 ports of 10-Gbps services aggregated over 100-Gbps DWDM wavelengths when combined with the Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card.

Operating Modes
The Cisco ONS 15454 10-Port 10 Gbps Line Card can support multiple applications.
10-Port10-Gbps Muxponder Application
The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card can be coupled with the Cisco ONS 15454 10-Port 10 Gbps Line Card to support 10 ports of 10-Gbps muxponder capabilities. The trunk card can be connected through the M6 or M2 backplane (no client CXP required) to the line card, providing Optical Transport Network (OTN) multiplexing of the 10-Gbps data streams into a single 100-Gbps DWDM OTU-4 wavelength. Supported client signals are any combination of 10 Gigabit Ethernet LAN-PHY, OC-192, STM-64, 10-Gigabit Fibre Channel (FICON), 8-Gigabit Fibre Channel (FICON} or OTU-2 data rates.
Figure 3. Three Cisco ONS 1545410-Port 10-Gbps Muxponder Applications in an M6 Chassis
5-Port 10-Gbps Transponder or Regenerator Application
The Cisco ONS 15454 10-Port 10 Gbps Line Card can work in a standalone mode supporting multiple 10-Gbps transponder functionalities. The 10-Gbps SFP+ ports are paired (Port 1 with Port 2, Port 3 with Port 4, and so on), providing 10-Gbps transponder functionality for each pair of ports. The most common use case is to use a grey SFP+ to connect to the client equipment and a DWDM SFP+ facing the network side. In this way, up to five 10-Gbps transponders can be supported by a single line card. Up to six Cisco ONS 15454 10-Port 10 Gbps Line Cards can be supported in an M6 chassis, allowing for thirty 10-Gbps transponders in a single shelf.
All ports can be equipped with or without a G.709 digital wrapper, providing wide flexibility in supported services. It is also possible to equip both SFP+ transceivers in a pair of ports with DWDM SFP+ pluggables, allowing 10-Gbps regenerator functionality.
CXP Fan Out Application
The Cisco ONS 15454 10-Port 10 Gbps Line Card can operate in a Fan Out mode providing a 10x 10GE interface on the client CXP into/from the individual 10 SFP+ interfaces on the card.
Licensing Approach
The Cisco ONS 1545410-Port 10 Gbps Line Card includes the ability to cost-effectively transport 10-Gbps services through a pay-as-you-grow licensing model for the 10-port 10 Gbps muxponder application (Table 1). A licensed version of the Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card works in conjunction with a licensed version of the Cisco ONS 15454 10-Port 10 Gbps Line Card, offering a cost-effective solution for aggregation and transport of 10-Gbps services. These two cards can only work in this configuration. Additional 10-Gbps services will be provided by mounting a 10-Gbps license through software key distribution. Up to nine 10-Gbps licenses can be added to the line card (only one 10-Gbps license is provided in the initial configuration).

The card can support a Forward Error Correction (FEC) mechanism on any of the SFP+ interfaces. This can be independently enabled or disabled on all the ports. For low-latency applications, a specific configuration is supported with FEC and OTN disabled for all the ports.
Two software-configurable Forward Error Correction coding options are available:
• GFEC: Standard G.975 Reed-Salomon algorithm with 7 percent overhead (OH)
• EFEC: Standard G.975.1 (Sub-clause I.7) with 7 percent overhead; this FEC scheme uses two orthogonally concatenated BCH super-FEC codes, and the constructed code is decoded iteratively to rebuild the original frame
Protocol Transparency
The Cisco ONS 15454 10-Port 10 Gbps Line Card can transparently deliver any 10-Gbps service for cost-effective, point-to-point transport within the Cisco ONS 15454 MSTP platform.
In the 100-Gbps muxponder application, clients are mapped into an OTU-4 DWDM wavelength using the mapping methods indicated in Table 2.

Wavelength Tunability
The Cisco ONS 15454 10-Port 10 Gbps Line Card is software provisionable and tunable across the full C-band, on 96 channels on the 50-GHz grid using tunable SFP+ pluggables. Tunability provides flexibility and reconfigurability of services transported on reconfigurable optical add-drop multiplexer (ROADM) based networks, but also allows management of a single element from a deployment and sparing perspective.
Flexible Protection Mechanism Support
The Cisco ONS 15454 10-Port 10 Gbps Line Card supports multiple protection mechanisms commonly used in optical transport networks. Table 3 outlines the available protection options and the associated service-level agreements (SLAs) that can be provided.
Table 3. Protection Formats
Protection Type
Capabilities
Unprotected
No client terminal interface, transponder card, or DWDM line protection.
The client signal is transported over a single unprotected transponder card or optical path.
Y-cable protection
Provides transponder card and DWDM line protection without requiring client terminal interface protection.
Uses Y-protection devices to optically split a single client interface to two transponder cards. The Cisco ONS 15454 system controls the transponder card active or standby status to provide a single signal feed to client equipment.
OCH-trail protection
Provides protection for the DWDM signal through external optical switch units (Protection Switch Module [PSM]).
Flow-Through Timing
The Cisco ONS 15454 10-Port 10 Gbps Line Card allows the timing to flow through from client to line optical interface. The received timing from the client interface is used to time the line transmitter interface. This flow-through timing allows multiple line cards to be placed in the same shelf, each timed independent of the network element timing.
Management
The Cisco ONS 15454 MSTP provides comprehensive management capabilities to support the Operations, Administration, Maintenance, and Provisioning (OAM&P) capabilities through the integrated Cisco Transport Controller craft interface with support from the Cisco Prime™ Optical element management system. The Cisco ONS 15454 10-Port 10 Gbps Line Card features provisionable digital wrapper (G.709) functionalities, providing per-wavelength performance management capabilities, especially for services transported transparently across the network. Without the digital-wrapper functions, a carrier transporting a service transparently would be unable to identify network impairments that may degrade the transported signal and violate the SLA agreements. The digital wrapper's Generic Communication Channel (GCC) provides a separate communications channel on a per-wavelength basis to be used by the platform when transparent signals are transported. GCC allows the Cisco ONS 15454 MSTP system to extend its advanced network autodiscovery capabilities to DWDM-based services. The integrated Cisco Transport Controller craft manager and Cisco Prime Optical provide the user with OAM&P functionalities for the system.
Far-End-Laser-Off Behavior
The Cisco ONS 15454 10-Port 10 Gbps Line Card can provision the far-end-laser-off behavior in case of SONET/SDH/OTN payloads. Customers can use Cisco Transport Controller to configure how the remote client interface will behave following a fault condition. It is possible to configure the remote client to Squelch or to send an Alarm Indication Signal (AIS).
For 10 Gigabit Ethernet or 10-Gbps or 8-Gbps Fibre Channel signals, the default behavior is Squelching.
Performance Monitoring
The digital wrapper channel is monitored according to G.709 (OTN) and G.8021 standards. Performance monitoring of optical parameters on the client and DWDM line interface include Loss of Signal (LOS), Laser Bias Current, Transmit Optical Power, and Receive Optical Power. Calculation and accumulation of the performance monitoring data are supported in 15-minute and 24-hour intervals as per G.7710.
• SONET performance monitoring is available according to the Telcordia GR-253 standard.
• SDH performance monitoring is available according ITU-T G826 and ITU-T G.828.
• 10 Gigabit Ethernet and partially Fiber Channel rates are compatible with the Remote Monitoring (RMON) standard.
A detailed list of performance monitors is given in Table 6.
The Cisco ONS 15454 10-Port 10 Gbps Line Card incorporates faceplate-mounted LEDs to provide a quick visual check of the operational status of the card. An orange circle is printed on the faceplate, indicating the shelf slot in which the card can be installed.
