Nokia buys Elenion for its expertise and partnerships

Nokia will become the latest systems vendor to bolster its silicon photonics expertise with the acquisition of Elenion Technologies. 

The deal for Elenion, a privately-held company, is expected to be completed this quarter, subject to regulatory approval. No fee has been disclosed.

“If you look at the vertically-integrated [systems] vendors, they captured the lion’s share of the optical coherent marketplace,” says Kyle Hollasch, director of optical networking product marketing at Nokia. “But the coherent marketplace is shifting to pluggables and it is shifting to more integration; we can’t afford to be left behind.”

ECOC 2019 industry reflections

Gazettabyte is asking industry figures for their thoughts after attending the recent ECOC show, held in Dublin. In particular, what developments and trends they noted, what they learned and what, if anything, surprised them. Here are the first responses from Huawei, OFS Fitel and ADVA.

At ECOC, one technology that is becoming a hot topic is machine learning. There is much work going on to model devices and perform optimisation at the system level.

And while there was much discussion about 400-gigabit and 800-gigabit coherent optical transmissions, 200-gigabit will continue to be the mainstream speed for the coming three-to-five years.

ECI Telecom details its cell-site gateway for 5G

ECI Telecom has unveiled its cell-site router for 5G that also supports existing 3G and 4G wireless standards. 

“You need to support the existing one or two generations of cellular networks,” says Jimmy Mizrahi, ECI’s executive vice president and head of global portfolio.

Jimmy MizrahiThe platform, the NPT 1022 cell-site router, is the first of several platforms that ECI will launch for 5G as it upgrades and expands its Neptune product line.

“The 1022 is part of a new line of products covering all layers of the network, starting at the cell site and going to aggregation and the metro core,” says Ezra Yehezkel, product line manager, packet transport solutions at ECI.

The Neptune portfolio will include a high-capacity packet-processing platform that can scale to 16 terabits.

Acacia bets on silicon as coherent enters its next phase

Gazettabyte interviewed Acacia Communications’ president and CEO, Murugesan ‘Raj’ Shanmugaraj, as the coherent technology company celebrates its 10th anniversary.

Acacia Communications has come a long way since Raj Shanmugaraj (pictured) first joined the company as CEO in early 2010. “It was just a few conference rooms and we didn't have enough chairs,” he says.

The company has since become a major optical coherent player with revenues of $340 million in 2018; revenues that would have been higher but for the four-month trade ban imposed by the US on Chinese equipment maker ZTE, an Acacia customer.

And as the market for coherent technology continues to grow, Acacia and other players are preparing for new opportunities. 

“We are still in the early stages of the disruption," says Shanmugaraj. “You will see higher performance [coherent systems] in some parts of the network but there is going to be growth as coherent moves closer to the network edge.”

Access drives a need for 10G compact aggregation boxes

Infinera has unveiled a platform to aggregate multiple 10-gigabit traffic streams originating in the access network. 

The 1.6-terabit HDEA 1600G platform is designed to aggregate 80, 10-gigabit wavelengths. The use of ten-gigabit wavelengths in access continues to grow with the advent of 5G mobile backhaul and developments in cable and passive optical networking (PON).

Also shown is how DWDM technology is moved closer to the edge of the network. Source: Infinera.

Infinera has adopted a novel mechanical design for its 1 rack unit (1RU) HDEA 1600G that uses the sides of the platform to fit 80 SFP+ optical modules. 

The platform also features an Ethernet switch chip that aggregates the traffic from the 10-gigabit streams to fill 100-gigabit wavelengths that are passed to other switching or transport platforms for transmission into the network.

Intel targets 5G fronthaul with a 100G CWDM4 module

• Intel announced at ECOC that it is sampling a 10km extended temperature range 100-gigabit CWDM4 optical module for 5G fronthaul. 

• Another announced pluggable module pursued by Intel is the 400 Gigabit Ethernet (GbE) parallel fibre DR4 standard.

• Intel, a backer of the CWDM8 MSA, says the 8-wavelength 400-gigabit module will not be in production before 2020.

Intel has expanded its portfolio of silicon photonics-based optical modules to address 5G mobile fronthaul and 400GbE.

Robert BlumAt the European Conference on Optical Communication (ECOC) being held in Rome this week, Intel announced it is sampling a 100-gigabit CWDM4 module in a QSFP form factor for wireless fronthaul applications.

The CWDM4 module has an extended temperature range, -20°C to +85°C, and a 10km reach.

“The final samples are available now and [the product] will go into production in the first quarter of 2019,” says Robert Blum, director of strategic marketing and business development at Intel’s silicon photonics product division.

ONF’s operators seize control of their networking needs

• The eight ONF service providers will develop reference designs addressing the network edge.
• The service providers want to spur the deployment of open-source designs after becoming frustrated with the systems vendors failing to deliver what they need. 
• The reference designs will be up and running before year-end.
• New partners have committed to join since the consortium announced its strategic plan

The service providers leading the Open Networking Foundation (ONF) will publish open designs to address next-generation networking needs.

Timon SloaneThe ONF service providers - NTT Group, AT&T, Telefonica, Deutsche Telekom, Comcast, China Unicom, Turk Telekom and Google - are taking a hands-on approach to the design of their networks after becoming frustrated with what they perceive as foot-dragging by the systems vendors.

“All eight [operators] have come together to say in unison that they are going to work inside the ONF to craft explicit plans - blueprints - for the industry for how to deploy open-source-based solutions,” says Timon Sloane, vice president of marketing and ecosystem at the ONF.
