Juniper Simplifies DCI with Innovative Coherent DWDM Line Card

by Juniper Employee ‎09-13-2017 12:45 PM - edited ‎09-13-2017 12:48 PM

Over two decades ago, when a friend of mine visited his parents in a remote countryside village in China, he had to first take train from Beijing to the provincial capital, then take a crowded coach on bumpy country roads to the county’s capital, next take passenger ship, and finally walk dozens of miles on the mountainous road to his parents’ village. The journey involved many forms of transportation, was exhausting, and took three days. Additionally, the logistics was difficult to manage and coordinate.


This problem also exists in networking industry. The explosion in data center traffic growth due to distributed applications such as distributed cloud applications, video streaming, and mobile applications is making it necessary to interconnect geographically dispersed locations to create a single hyper-scale logical resource pool. To achieve this interconnectivity, cloud operators have been deploying isolated packet and dense wavelength-division multiplexing (DWDM) equipment as separate domains with independent management tools. Just like my friend visiting his parents in the remote village, this infrastructure involves a diverse set of transportation domains and is difficult to manage.


In a linear optical network that contains multiple optical nodes, it is an operational goal to optimize the end-to-end optical network performance, measured by the receiving node’s optical BER (Bit Error Rate). And as time goes on, the receiving node’s BER can drift, due to factors such as the sending node’s transmitting optical power drifting, ambient temperature variation, equipment aging, etc. While some factors are difficult to control, such as ambient temperature variation and equipment aging, the sending node’s transmitting optical power is easily controllable and can be adjusted to compensate for the BER drifting due to other factors. So if we can continuously monitor the receiving node’s real-time BER, provide feedback to the sending node, and adjust the sending node’s transmitting optical power as needed, we can obtain the optimal end-to-end optical network performance.


Juniper Networks Tells its Remarkable Optical Story at OFC17 in LA!

by Juniper Employee ‎04-05-2017 01:55 PM - edited ‎04-13-2017 12:09 PM

When Juniper Networks recently announced its latest Data Center Interconnect (DCI) solution, the company decided this year’s Optical Fiber Conference (OFC)—the industry’s largest event for optical communications and networking companies—was the best place to amplify that message.  


To support this big announcement, Juniper’s Technical Marketing team was tasked with producing a demonstration that showcased the solution’s various components.  Underscoring the company’s confidence in the quality and stability of its products, the demo was to be conducted live, with full IP/MPLS traffic running, for all five days of the conference.





Juniper's Open Cloud Interconnect: There's More to DCI than Turning Up Wavelengths

At Juniper, everything we’re doing to bring packet and optical technologies together in new, innovative ways is designed to drive our customers’ cloud businesses forward—unconstrained by the status quo of vendor lock-in, network control silos, operational complexity and interoperability challenges.


Next week at OFC 2017, this theme is weaved throughout our product and solution announcements, demos, speaking gigs, technical submissions and Expo Theater 2 event.


Join us as we showcase our innovation and collaboration with partners and customers to build better cloud businesses.


Juniper and TIP: Driving Open and Disaggregated Packet-Optical Transport

by Juniper Employee ‎10-31-2016 03:41 PM - edited ‎03-21-2017 03:01 PM

On November 1 and 2, Juniper will join a growing community of content and cloud operators, telecom service providers and technology vendors participating in the inaugural Telecom Infrastructure Project (TIP) Summit. Similar to the goals of Open Compute Project in the IT world, TIP’s mission is to explore new approaches to building hyper-scale telecom networks—in particular, to accelerate innovation through the power of open network architectures.


Juniper Hits A Grand Slam With Its Open And Flexible 400G Solution

by Juniper Employee ‎10-03-2016 09:23 PM - edited ‎10-05-2016 10:36 AM




With the Major League Baseball playoffs upon us, there is no better reference to make for Juniper’s latest coherent DWDM solution than to a grand slam. For those that may not be familiar with this reference, a grand slam is when a player hits a homerun while all the bases are loaded, resulting in the team getting four runs instantly. In other words, it’s a big deal !

Lately, Juniper has been on a roll with the release of several next generation high capacity Coherent DWDM solutions including the 1 x 100G DWDM Coherent MIC and 5 x 100G DWDM Coherent PIC, Optical ILA and Integrated ROADM IPLC. Now, yet again, Juniper hits it out of the ballpark with a 400G coherent solution. Using the industry’s latest innovation in coherent technology, Juniper has developed an open and flexible ultra high capacity 400G Muxponder/Transponder. This 400G solution aka UFM6 (Universal Forwarding Module 6) provides a transport capacity of not 100Gbps, not 200Gbps but 400Gbps on single module. This enables up to 19.2 Tbps capacity on single pair of fiber using 96 x 200Gbps channels. That’s a grand slam !

Now let’s break this down a bit. Starting with the client ports, the UFM6 consists of 10 total physical client ports, either QSFP28 or QSFP+, which can be connected to high capacity routers or switches. While each of the QSFP28 ports support 100GE interfaces, the QSFP+ ports can support multi-service capabilities including 10GE, OC192/STM64, OTU2 and OTU2e. Together, these can enable either 4 x 100GE’s via the QSFP28 ports or 40 x 10G via the QSFP+ ports on the same UFM6 module. The UFM6 also supports a lineside capacity of up to 400Gbps via 2 x 200G Coherent DWDM channels using OTU4 encapsulation. Each lineside DWDM channel is software configurable to 200G 16QAM or 100G QPSK and supports full tunability across the C-band with 50GHz spacing. The UFM6 also supports SD-FEC for maximum performance across metro, regional and long haul spans up to 2000 km. For maximum deployment flexibility, the UFM6 can be supported in 3 different chassis options including the 7801 (1 RU), 7802 (3 RU) and 7814 (14 RU).

Now that we've got all the technical jargon out of the way, let’s talk about the “open” aspects of this 400G solution. The UFM6 supports open northbound interfaces via NETCONF/YANG enabling management through not just Juniper’s own control software (see Juniper's PSM) but also enabling providers to use their own transport controllers to fully manage this solution. This opens the door for operators to customize this solution to their needs and enables new and innovative applications.


To sum it all up Juniper’s new UFM6 400G Muxponder/Transponder enables:

  • Ultra high capacity Packet Optical networks up to 19.2 Tbps
  • Open and automated solutions via NETCONF/YANG interfaces
  • Flexible solutions using software provisionable coherent interfaces 

As service providers, web 2.0’s and enterprises try to keep up with demand for the immense traffic growth on their networks driven by cloud services including (SaaS, PaaS, NaaS etc.) mobile traffic (LTE) and HD entertainment services (HD, Ultra HD etc.) Juniper continues to alleviate capacity bottlenecks with innovative coherent DWDM solutions. However, we are not done just yet, so stay tuned for more groundbreaking technology from your Juniper team as we continue to hit it out of the park !

All You Can Eat DWDM

Working up an appetite for packet-optical capacity? Time to supersize DWDM transport on PTX...Everyone has heard of "too much of a good thing". Whoever came up with that probably wasn't running a network. Those of us trying to keep up with insatiable data demands always need more. More capacity. And more tacos.




What happens when Birkenstocks and Pocket Protectors Get Together?

by Juniper Employee ‎09-28-2016 05:01 PM - edited ‎09-30-2016 01:16 PM

Nerds Rule!!Nerds Rule!!

Product evolution in networking technology is a fascinating place. Years ago it would be hard to imagine the convergence of packet and optical technologies. Those that wear Birkenstocks and start companies in their garages vs, those in white collared shirts with pocket protectors developing products in research & development laboratories of large national telecommunication companies.  They evolved from such different starting places. The DWDM products of today evolved out of the need to expand and improve the telecommunications infrastructure. It took 140 years for the telecommunications network to evolve to its current form.
