Juniper calls it the OTS1000, and it's been on display at OFC/NFOEC all week.
The OTS acts as the optical shelf for one or more PTXs. It's where the DWDM transponders for the PTX could reside, for instance, if a carrier opts to not use IP-over-DWDM. The OTS would also house things like ROADMs or add/drop multiplexers -- in other words, everything the FSP 3000 does.
So, it plays a key role in what Juniper calls the converged supercore, the conceptual unit that also includes the PTX and Juniper's T-series core routers. (See Juniper Makes Its Packet-Optical Move.)
The OTS wasn't mentioned at all in last week's PTX launch. Juniper will sell and support the box, but only as a companion to the PTX. Juniper will never sell the OTS by itself, says Luc Ceuppens, Juniper's senior director of marketing. (Makes sense; they'd basically be doing ADVA's job, which might strain that relationship a little.)
One key element of the OTS is that it's running Junos and uses the same management system as the PTX. Juniper's software treats the OTS and PTX as one unit.
They probably won't ever be physically integrated, Ceuppens says. The boxes have fundamentally different backplanes. The PTX uses an active backplane because it's likely that some traffic will hop from one blade to another. Optical systems don't do that, so the OTS has a passive backplane.
This does make things a little clearer. It was obvious Juniper would avoid doing many of the optical elements itself ... Juniper doing its own IPoDWDM transponders is believable, but things like ROADM were clearly going to come from outside. (Juniper had already told us ROADM would be done by ADVA; I'm just using that as an example.)
The management aspect seems key here. The supercore's superpower might be that you've got these multiple elements -- routers, MPLS switch, optical transport -- run by the same software.

Six different communications service providers join to debate their visions of the future CSP, following a landmark presentation from AT&T on its massive virtualization efforts and a look back on where the telecom industry has been and where it's going from two industry veterans.
At Light Reading's NFV & Carrier SDN event in Denver, Ray Watson, vice president of Global Technology at Masergy, says that because of the growth in virtualization, the threat landscape is shifting in favor of the attackers. As a result, service providers need to think beyond just defending the perimeter and take a more holistic approach to security.
At September's NFV & Carrier SDN event in Denver, Light Reading sat down with Victoria Lonker, director of Product and New Business Innovation at Verizon, to chat about where the carrier is with delivering virtualized services to business customers.
Nick Thomas, practice leader of digital media at Ovum, talks about how digital transformation in the technology, media and telecom sectors will enable the development of a new range of applications and services for enterprises and consumers and how the upcoming Digital Futures event in London will examine ...
Heavy Reading Senior Analyst Jim Hodges speaks with Accenture's Larry Socher and Matt Anderson about what service providers must do to transform their business to get the benefits of SDN and NFV including: leveraging DevOps, introducing real-time OSS and implementing analytics.
VeEX's Senior Director of Business Development, Perry Romano, explains how VeEX provides tools to help install, maintain, monitor and manage network infrastructure efficiently and effectively. The portfolio of products on display include the RXT-6000, MTTplus and TX300s.
Light Reading Editor Mitch Wagner talks to NetScout CMO Jim McNiel about maximizing the benefits of enterprise cloud and digital transformation while minimizing potential pitfalls with a proper monitoring and instrumentation strategy.
Many of the initial use case implementations are single-vendor and self-contained. The industry is still climbing the virtualization maturity curve, needing further clarity and stability in the NFV infrastructure (NFVi) and greater availability and choice of virtualized network functions (VNFs). Interoperability between NFVis and VNFs from different vendors ...
Join us for an in-depth interview between Steve Saunders of Light Reading and Alexis Black Bjorlin of Intel as they discuss the release of the company's Silicon Photonics platform, its performance, long-term prospects, customer expectations and much more.
A vital part of increasing the number of women in comms is transforming the ways companies can support and empower women. While progressive company policies that support both men and women in achieving work-life balance are a step in the right direction, creating a company culture that supports those policies can at times be more challenging.
During this show, we'll talk to Lynn Comp, Senior Director of Industry and Sales Enabling (ISE) in the Network Platforms Group at Intel, about why those challenges exist and how companies can overcome them. She'll provide insight into how Intel has worked to create a culture that supports work-life balance, and provide steps and guidance for other companies wishing to do the same. We will also leave plenty of time to get your questions answered live on the air.
