MSRP on New $250,000

The module connects directly into any DWDM network and provides up to 100 Gbps of data throughput, transporting 100 Gigabit Ethernet LAN Physical Layer (LAN-PHY) and Optical Transport Network (OTN) Transport Unit Level 4 (OTU-4) over a 50-GHz spaced, 50-GHz stabilized, ITU-compliant wavelength. The module is completely tunable across the C band in the ITU 50-GHz grid. The unit uses a Coherent Polarization-Multiplexed Differential Quadrature Phase Shift Key (CP-DQPSK) modulation scheme that is based on the Optical Internetworking Forum (OIF) standard

Challenge and Solution

The bandwidth carried on core and metropolitan (metro) DWDM networks is growing exponentially, while operators’ revenues are not growing as quickly. The Cisco CRS 1-Port 100 Gigabit IPoDWDM solution can dramatically lower the cost to carry bandwidth, helping to maintain and improve customers’ profitability in the face of exponential Internet growth due to demand for next-generation services such as Quad play (data, voice, video, and mobility), video distribution, Internet Protocol Television (IPTV), and other high-bandwidth services.

The possibility of transmitting 100-Gbps wavelengths on existing or new Greenfield DWDM systems improves return on investment by increasing the overall capacity per fiber pair without impacting the unregenerated transmission distance, which can be covered through the advance modulation schemes. The scale of 10 Gbps to 40 Gbps and now to 100 Gbps multiplies by a factor of 10 the bandwidth that can be transported over existing fiber networks.

The new Coherent Polarization-Multiplexed Differential Quadrature Phase Shift Key (CP-DQPSK) modulation enables 100-Gbps capacity transmission over existing 10/40-Gbps networks, up to 3000 km, thus enabling Ultra Long Haul (ULH) networks of unregenerated optical links.

The new interface module is designed to provide the following benefits:

●   Transport of 100-Gbps wavelengths over fully uncompensated networks, up to 3000 km of unregenerated optical links

●   Transport at 100 Gbps over very low-quality fiber with very high Polarization Mode Dispersion (PMD)

●   Transport of 100-Gbps wavelengths over existing 50-GHz channel spacing with very high tolerance to filtering penalties

This module helps service providers increase efficiency, improve reliability, and reduce operational and capital costs by eliminating expensive and bulky optical transponder equipment.

Enhanced Forward Error Correction Capability

This module can support a Forward Error Correction (FEC) mechanism. The trunk port supports three software- configurable FEC coding options.

●   Generic FEC (GFEC): Standard G.975 Reed-Salomon algorithm with 7 percent overhead.

●   Ultra FEC (UFEC): Standard G.975.1 (Sub-clause I.7) with 20 percent overhead. This FEC scheme uses two orthogonally concatenated BCH Enhanced FEC (EFEC) codes. The constructed code is decoded iteratively to rebuild the original frame.

●   High-Gain FEC (HG-FEC): High-Gain EFEC with 7 percent overhead, providing better performances than standard G.975.1 7 percent OH FEC. Because of the reduced overhead and lower bit rate, HG-FEC is suitable for all the applications where 100 Gbps wavelengths are passing through a high number of reconfigurable optical add-drop multiplexer (ROADM) nodes with limited pass-band performances.

The different FEC modes extend the reach of the DWDM signal up to 3000 km without requiring signal regeneration. For more information about the Cisco CRS or about other interfaces available for the Cisco CRS, visit: http://www.cisco.com/go/crs.

Protocol Transparency

The module can transparently deliver any 100-Gbps services for cost-effective, point-to-point networking for the Cisco CRS platform (see Table 1).
