Cisco ONS 15454 2-Port CFP Line Card Data Sheet

Product Overview

The Cisco^® ONS 15454 Multiservice Transport Platform (MSTP) supports a 2-port C Form-Factor Pluggable (CFP) line card, which simplifies the integration and transport of 100-Gigabit interfaces and services into enterprises 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) in the C-band.

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.

The new coherent polarization-multiplexing differential quadrature phase shift keying (CP-DQPSK) modulation scheme supports 9.6 Tbps capacity transmission over Ultra-Long-Haul (ULH) networks of up to 3,000 km of unregenerated optical spans.

The Cisco ONS 15454 2-Port CFP Line Card is designed to provide 100-Gbps services over 100-Gbps DWDM wavelengths generated by the Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card.

Product Features and Benefits

The Cisco ONS 15454 2-Port CFP Line Card consists of two ports capable of hosting a CFP transceiver. Each port can support following services:

●   40 Gigabit Ethernet

●   100 Gigabit Ethernet

●   OTU-3

●   OTU-4

Client ports can be equipped with a large variety of pluggable CFPs.

The Cisco ONS 15454 2-Port CFP Line Card provides the carrier-class features and advanced capabilities necessary to deliver 100-Gbps services, including protocol transparency, flexible protection mechanisms, flow-through timing, and management and performance monitoring capabilities (Figure 2).

Operating Modes

The Cisco ONS 15454 2-Port CFP Line Card supports multiple applications.

100-Gbps LR4 Transponder Application

The Cisco ONS 15454 2-Port CFP Line Card can be coupled with the Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card to support a 100GBASE-LR4 client interface for the 100-Gbps transponder. The 100-Gbps CXP pluggable available on the Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card currently supports only 100GBASE-SR10, while 100GBASE-LR4 currently requires a CFP form factor.

The Cisco ONS 15454 2-Port CFP Line Card can be connected through the ONS 15454 M6 or M2 backplane with up to two 100-Gbps coherent DWDM trunk cards placed in the slots above or below the same shelf to provide the functionality of two 100-Gbps transponders, with 100GBASE-LR4 CFP pluggables as the client Interface.

2-Port 40-Gbps Muxponder Application

The Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card can be coupled with the Cisco ONS 15454 2-Port CFP Line Card to support 40-Gbps muxponder applications. The trunk card can be connected through the Cisco ONS 15454 M2 or M6 chassis backplane to the Cisco ONS 15454 2-Port CFP Line Card to provide Optical Transport Network (OTN) multiplexing of the two 40-Gbps data streams into a single 100-Gbps DWDM OTU-4 wavelength (Figure 3).

Supported client signals are any combination of 40 Gigabit Ethernet LAN-PHY or OTU-3 data rates.

Protocol Transparency

The Cisco ONS 15454 2-Port CFP Line Card can transparently deliver any 40-Gbps or 100-Gbps service for cost-effective, point-to-point transport using the Cisco ONS 15454 MSTP platform.

In the 100-Gbps muxponder application, clients are mapped into an OTU-4 DWDM wavelength using the methods listed in Table 1.

Flexible Protection Mechanism Support

The Cisco ONS 15454 2-Port CFP Line Card supports multiple protection mechanisms commonly used in optical transport networks. Table 2 outlines the available protection options and the associated service-level agreements (SLAs) that can be provided.

Table 2.       Protection Formats

Flow-Through Timing

The Cisco ONS 15454 2-Port CFP 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 2-port CFP line cards to be placed in the same shelf but be 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.

Far-End-Laser-Off Behavior

The Cisco ONS 15454 2-Port CFP Line Card can provision the far-end-laser-off behavior in case of OTN payloads. Customers can use the 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 100- or 40-Gigabit Ethernet signals, the default behavior is Squelching.

Performance Monitoring

Performance monitoring for the Cisco ONS 15454 2-Port CFP Line Card takes into account the fact that the line card is a host board supporting CFP client equipment while the digital monitoring of the incoming client is implemented on the companion Cisco ONS 15454 100 Gbps Coherent DWDM Trunk Card. A virtual port connection displays the digital wrapper monitoring according to G.709 (OTN) as well Remote Monitoring (RMON) for Ethernet signals, while the optical performance monitoring is directly available on the 2-Port CFP Line Card. Calculation and accumulation of the performance monitoring data are supported in 15-minute and 24-hour intervals as per G.7710.

A detailed list of performance monitors is given in Table 5.

The Cisco ONS 15454 2-Port CFP 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.
