ekinops alien wavelengths: plug-and-play capacity …...bandwidth demand frequently causes...
TRANSCRIPT
BANDWIDTH DEMAND FREQUENTLY CAUSES UNCERTAINTY FOR SERVICE PROVIDERS WITH EXISTING WDM NETWORKS THAT ARE ILL
PREPARED TO ACCEPT NEW TRAFFIC. EITHER PORT EXHAUST ON EXISTING OPTICAL MULTIPLEXERS WILL REQUIRE LIGHTING A NEW FIBER PAIR,
A COSTLY AND TIME CONSUMING PROCESS MOST PROVIDERS CANNOT AFFORD TO UNDERTAKE, OR THE SERVICE LOAD IS GREATER THAN THE
INCUMBENT EQUIPMENT PLATFORM CAN SUPPORT, AT LEAST WITHOUT DEPLOYMENT OF NEW HARDWARE WHICH MAY NOT BE QUALIFIED
FOR THEIR NETWORK.
OFTEN THIS SITUATION WILL COME WITHOUT WARNING DESPITE A PROVIDERS’ BEST EFFORTS TO ACCURATELY FORECAST DEMAND. IT MIGHT
BE A LARGE ENTERPRISE THAT OPENED A NEW FACILITY IN THE REGION, UNEXPECTED GROWTH AT AN EXISTING CUSTOMER, OR MAYBE A
REFERRAL CUSTOMER THAT HAS AN IMMEDIATE NEED. IN THIS TYPE OF DYNAMIC ENVIRONMENT, ANY PROVIDER OF HIGH CAPACITY
WAVELENGTH SERVICES NEEDS TO HAVE A PLAN FOR ADDRESSING ALL BANDWIDTH REQUESTS, FORESEEN AND UNFORESEEN. FAILURE TO
DELIVER IS NOT AN OPTION. WHAT IS NEEDED IS A HIGHLY FUNCTIONAL, REPEATABLE SOLUTION THAT ALLOWS ADDING ANY AMOUNT OF
CAPACITY TO ANY SPAN AT ANY TIME WITH A LEVEL OF MANAGEABILITY THAT KEEPS OPERATIONAL EXPENSES LOW WHILE DELIVERING
GUARANTEED PERFORMANCE OVER ANY DISTANCE FROM 10 KILOMETERS TO 10,000 KILOMETERS.
An “alien” wavelength is any wavelength that originates on networking equipment that is not the same as the equipment used in the optical line
system. It can be from a different type of equipment such as a router with colored optics connected to an optical line system even if they are
both from the same vendor. It also can be a wavelength that is launched from third party optical transport equipment (see Figure 1).

Alien wavelengths are used for a variety of reasons. One is that the existing line system may be limited to 40, 32 or even 16 wavelengths and may
have no capability for expansion. Another is that the incumbent vendor may be charging too much money for additional transponders in an effort
to recoup margin. Yet another reason may be because the incumbent vendor no longer exists or has been acquired by a competitor that the
service provider doesn’t want in its network.
Another benefit of coherent technology is that it allows high speed
channels—100G and above—to operate over spans with poor perfor-
mance. Though optimized around the current generation of line sys-
tems, coherent technology allows 100G, 200G and higher line rates to
also operate over line systems from previous generations that have dif-
ficulty even supporting lower speed 10G traffic. The ability of the Digital
Signal Processor (DSP) to digitally correct the analog impairments that
occur in optical networks allows these high speed channels to over-
come any limitations imposed by the fiber plant.
Because they use coherent technology with different modulation tech-
niques, high speed 100G, 200G, 400G or even 600G wavelengths have
superior chromatic dispersion tolerances that allow them to more easi-
ly co-exist with the 10G wavelengths already operating on the line.
Even in cases where the use of guard bands is required, the additional
capacity gained from using the higher speed channels more than com-
pensates for loss of a single guard band wavelength. Combined, these
factors give coherent based solutions an enormous advantage over
10G from a cost vs. performance standpoint.

The alien wavelength market began with the introduction of 10G technology to add high capacity channels to existing lower speed 2.5G networks.
However, the problem was that the fiber plant designed for 2.5G created chromatic dispersion problems for 10G channels. For this reason and
because of the high cost of 10G technology at the time, alien wavelengths remained a niche application.
With the introduction of coherent technology, the cost of high speed optical transport declined at a rate unprecedented in the history of the
industry. In today’s market, 100G transport is available for over 40% less than the cost of 10G (see Figure 2), while 200G is half the cost driving it rapidly
to becoming the de facto bit rate in metro, regional and even long haul transport networks.

n RELIEVING FIBER EXHAUST
The main use case for alien wavelengths is relieving fiber exhaust. As networks reach their channel capacity limits, service providers are looking for
ways to leverage the existing fiber plant. In most cases, the time and cost required to light a new fiber pair is prohibitively expensive. In some cases,
the scarcity of fiber may make it impossible altogether.
Alien wavelengths can provide the needed capacity at low cost and in a much shorter timeframe compared to lighting new fiber. Even in networks
where capacity is completely exhausted, alien wavelengths can be used to replace existing low speed channels allowing the network operator to
reclaim capacity on the existing line system (see Figure 3).
n EKINOPS SOLUTION
With the cost of coherent technology continuing to fall and bandwidth continuing to grow, the market for ultra-high speed solutions is rapidly
replacing 10G across metro, regional and core networks (see Figure 4). To meet this demand, Ekinops has developed a series of high speed line
modules for its modular C600HC and C200HC chassis that address any application from very short metro access links to ultra-long haul spans.

With bandwidth growth inevitable and ongoing, more link capacity
will always be needed whether in the core, the metro or even the
access portion of the network. As such, it is in the networks operator’s
interest to deploy as much bandwidth as their budget will support to
accommodate future growth. To address this need, Ekinops has
developed its Flexrate line modules that have the ability to deliver
anywhere from 100G to 600G of capacity simply by selecting the
desired line rate and modulation format from the management
interface. This flexibility allows the network operator to match capacity
to current demand.
For example, the PM 400FRS04 (see Figure 5) can be initially provisioned
for 100G of capacity to meet immediate bandwidth needs and then
re-programmed via software as demand grows without having to buy
a new module or swap out hardware. The modulation format can also
be set to meet certain reach requirements. For local access, the
modulation format can be set to deliver 600G over shorter distances.
Alternately it can be set to deliver 100G to reach ultra-long haul
distances up to 10,000 Km, or any distance in between to optimize the
capacity vs. reach trade-off.
For applications such as wireless backhaul where space availability is limited and where only a single high speed channel is required, the Ekinops
RM 10001-WB and RM 10010-WB (see Figure 6) provide a 100G 1RU transponder and muxponder respectively with long haul transport capability
up to 6000 Km.

With its ease of deployment over existing line systems combined with minimal space and power requirements, Ekinops alien wavelength solutions
help save on operations costs in addition to the equipment savings they provide.
All it requires is installing a small chassis (1RU or 2RU depending on your needs), connecting it to power, and connecting patch cables to the client
device on one side and the existing optical multiplexer on the other. From there, it’s just a matter of establishing management connectivity—
either in-band or out-of-band—and turning up the wavelength (see Figure 7).
In band management simplifies operations because it only requires management connectivity to the near end. The embedded 10 Mbps Data
Communications Channel (DCC) provides remote connectivity to the far end node without interfering with customer traffic.

n PLATFORM FLEXIBILITY
EKINOPS360® Platform is purpose-built as a highly flexible system on several levels. The C600HC and C200HC chassis are modular units that can
be customized to meet any service provider need or support any application simply by installing the service modules that best fit their needs.
Multiprotocol client support for everything from 100M to 100G gives service providers the ability to support any type of service demand. Multi-
level aggregation capability allows low speed services (FastE, GbE, OC-3/STM-1, OC-12/STM-4, SD/HD video etc.) to be carried on high speed
wavelengths to maximize bandwidth utilization. With its “any card, any slot” design, the 360 Platform allows service providers to use any open slot
to add capacity without restrictions. The same hardware and software technology is also used in our 1RU RM 10001-WB and RM 10010-WB units
making them completely interoperable with the modular shelves extending the capabilities of the platform to space constrained locations. The
EKINOPS360® Platform can operate on both dual fiber and single fiber networks making it highly adaptable to any network configuration.
n MANAGEMENT
At the element level, the Flexrate modules as well as the RM 10001-WB and RM 10010-WB shelves can be managed through SNMP or via the Ekinops
standard element level management interfaces, which includes a Command Line Interface (CLI) and an Ekinops Graphical User Interface (GUI). The
CLI is accessible via SSH and Telnet remotely or via a local serial port locally. Complete performance monitoring and management is provided.
Digital Diagnostics Management (DDM) is supported for pluggable client interfaces. A 10 Mb in-band Data Communications Channel (DCC) is
embedded in the line side for remote management.
All hardware elements are supported by EkiCraft, the Ekinops Craft Interface and Celestis NMS, the Ekinops network management system. SDN-
capable, Ekinops solutions can also be managed using any controller via NETCONF interface in addition to Ekinops management tools. Celestis
NMS easily integrates into any service provider management platform using standards-based northbound interfaces (NBI) to higher layer OSS/BSS
systems.

ABOUT EKINOPS
n CONCLUSION
Increasing bandwidth demand is a problem without end. Many existing WDM networks were not designed to meet today’s capacity needs and
are quickly running out of room to grow. With the cost and time required to overbuild a new network, it is not a viable option in most cases. What
is needed is a solution that can leverage the existing network by adding capacity on the current line system.
Coherent technology makes it possible to add 100G, 200G, 400G and even 600G of capacity to 10G networks without disrupting existing
wavelengths. The capacity, distance and cost advantages that coherent technology provides has transformed alien wavelengths from a niche
application to a viable solution for capacity constrained networks.
Ekinops 360 Platform, with its modular Flexrate and 1RU solutions, provides the highest performance and greatest flexibility available and can be
easily deployed in any service provider network. The 360 Platform has a proven history of operating over any third-party line system, often
outperforming the channels provided by the incumbent equipment vendor. With its broad service range and ease of management, Ekinops 360
is the solution of choice for alien wavelength applications.
