CS6001/2/3/4/5 Next Generation G.709 Optical Transport Processor Platform for 10G and 40G
Product Overview
Demand for bandwidth-intensive applications such as
video-on-demand, music downloads, and telepresence
is growing, and network deliv ery of larger file formats
like HD video continues to gain in popularit y. Telecom
equipment makers are looking for solutions that allow
them to deliver these bandwidth-intensive
experiences to consumers while k eeping their power
usage and costs in check. The new Cortina S ystems
®
CS600x Optical Transport Processor & FEC Device
(CS600x Transport Processor) enables carriers to
deliver high-quality, data-intensive services while
reducing operational and capital expenditures by
permitting efficient multiplexing and tr ansparent
transport of a broad spectrum of 10G class clients
including Ethernet, SONET/SDH, and Stor age over
high speed optical tr ansport networks as well as 40G.
The CS600x Transport Processor family offers
advanced analog integration, proven optical transport
networking, and FEC leadership . It aggregates and
transports a broad mixture of 10G Ethernet, 10G-
class storage, and SONET/SDH clients o ver 10G or
40G transport networks. Based on cutting-edge
technology, the CS600x Transport Processor offers a
rich feature set that allows for denser and more
flexible line cards for metro and long-haul dense
wavelength-division-multiplexing applications,
Ethernet switch and router platforms, and submarine
ultra long-haul systems. K ey features include
aggregation of four fully independent synchronous or
asynchronous 10Gs tributaries to a 40G signal; super
forward error correction ("Super FEC"); tr ansport,
mapping, and performance monitoring; and
networking support for v arious client signals.
The CS600x Transport Processor family is offered as
five different options that are specifically tailored to
various 40G or 10G applications.
• The CS6001 Transport Processor features two 17-
lane or 16-lane 40G-class interfaces (SFI -5.1 or
16-lane SFI-4.2), eight four-lane 10G-class
interfaces (XAUI or SFI-4.2), and four XFI serial
10G-class interfaces. Additionally, each SFI -5.1
interface can be down-clock ed to operate as a 16-
bit SFI-4.1 compliant interface. The CS6001
Transport Processor can handle full duplex
processing of either a single 40G signal or up to
four independent 10G signals. The receiv er and
transmit ports can be configured independently to
monitor (and optionally terminate) O TU3/OC-768,
40GE, and OTU2/OC-192/10 GbE/FC-1200/FC-800
signals.
• The CS6002 Transport Processor is tailored for 40G
Muxponder and Cross connect applications in the
DWDM, and P-OTP platforms.
• The CS6003 Transport Processor is targeted for
4x10G applications in the D WDM, OTN-crossconnect
applications.
• The CS6004 Transport Processor is targeted for
4x10G applications in the R outer/Switch market
place.
• The CS6005 Transport Processor is targeted for
2x10G applications.
The CS600x Transport Processor is compatible with
Cortina devices, such as the Cortina S ystems
®
CS2777, CS1222, CS3487, CS3477, and CS1999, on
the client side.
Aggregation
The CS600x Transport Processor supports a v ariety of
aggregation configurations. For example, the device
can be used to aggregate 10G clients oper ating at
different rates. Clients are independent - an y mix of
10GE LAN PHY, 10G SDH/SONET, 10G OTN, or
FC1200/800 is allowed. Con versely, an incoming
aggregate 40G signal can be asynchronously
de-aggregated to its original 10G clients. Additional
possibilities include 24 x GbE Aggregation to dual 10G
OTN for Long Haul WDM applications, NxGE
aggregation, or demultiplexing 10G Class Signals from
a 40G circuit backplane input.
10GE LAN Mapping
The CS600x Transport Processor supports man y
different methods, with v arying degrees of
transparency, to map and tr ansport 10 GbE LAN clients
over Transport Networks: by synchronously mapping
the 10 GbE LAN client o ver an OPU2 or OPU1 pa yload
(resulting in an O TU2 signal overclocked at 11.096
Gbps or 11.049 Gbps), by r ate adapting the 64B/66B
stream before mapping ov er OPU2 (or VC -4-64c)
payload, or by using GFP-F encapsulation before
mapping over OPU2
(or VC-4-64c).

Forward Error Correction
The 10G Super FEC scheme used in the CS600x
Transport Processor is the Ultr a-Strong FEC (UFEC)
supported by the industry leading Cortina S ystems
®
IXF30009/IXF30011 Optical Transport Processors and
specified in section I.7 of the ITU G.975.1
recommendation. The device also supports a similar
40G Super FEC scheme according Section I.7
("Ultra-Strong FEC") of the ITU G.975.1
recommendation. The device pro vides 10G & 40G
configurable ultra-FECs with 4%, 7%, 10%, 15%,
20%, and 25% FEC ov erhead rates with a net coding
