Edgecore exploits telecom’s open-networking opportunity

Part 2: Open networking

Edgecore Networks is expanding its open networking portfolio with cell-site gateways and passive optical networking (PON) platforms. 

The company is backing two cell-site gateway designs that aggregate traffic from baseband units for 4G and 5G mobile networks. One design is from the Open Compute Project (OCP) that is available now and the second is from the Telecom Infra Project (TIP) that is planned for 2019 (see table).

Edgecore has also announced PON optical line terminal (OLT) platforms addressing 10-gigabit XGS-PON and GPON.

Edgecore is a wholly-ownedsubsidiary of Accton Technology, a Taiwanese original design manufacturer (ODM) employing over 700 networking engineers that reported revenues exceeding $1.2 billion in 2017.

TIP launches a disaggregated cell-site gateway design

Part 1: TIP white-box designs

Four leading telecom operators, members of the Telecom Infra Project (TIP), have developed a disaggregated white-box design for cell sites. The four operators are Orange, Telefonica, TIM Brazil and Vodafone. BT is also believed to be backing the open-design cell-site venture.

The first TIP cell-site gateway product, known as Odyssey-DCSG, is being brought to market by ADVA and Edgecore Networks.

TIP isn’t the only open design framework that is developing cell-site gateways. Edgecore Networks contributed in October a design to the Open Compute Project (OCP) that is based on an AT&T cell-site gateway specification. There are thus two overlapping open networking initiatives developing disaggregated cell-site gateways. 

ADVA and Edgecore will provide the standardised cell-site gateways as operators deploy 5G. The platforms will support either commercial cell-site gateway software or open-source code.

Using an open-source model to spur AI adoption

The Linux Foundation’s (LF) Deep Learning Foundation has set itself the ambitious goal of providing companies with all the necessary artificial intelligence (AI) software they will need.

Eyal Felstaine“Everything AI, we want you to take from open source,” says Eyal Felstaine, a member of the LF Deep Learning governing board and also the CTO of Amdocs. “We intend to have the entire [software] stack.”

The Deep Learning Foundation is attracting telecom, large-scale data centre operators and other players. Orange, Ciena, Red Hat, Chinese ride-sharing firm, Didi, and Intel are the latest companies to join the initiative. 

The Deep Learning Foundation’s first project is Acumos, a platform for developers to build, share and deploy AI applications. Two further projects have since been added: Angel and Elastic Deep Learning.

Oclaro showcases its pluggable CFP2-DCO at ECOC

Multi-sourcing CFP2-DCO modules, coherent digital signal processor (DSP) partnerships, new laser opportunities and the latest on Lumentum’s acquisition of Oclaro. A conversation with Oclaro’s chief strategy officer, Yves LeMaitre.

Oclaro demonstrated its CFP2 Digital Coherent Optics (CFP2-DCO) pluggable module working with Acacia Communications’ own CFP2-DCO at the recent European Conference on Optical Communication (ECOC), held in Rome.

Yves LeMaitreOclaro announced earlier this year that it would use Acacia’s Meru coherent DSP for a CFP2-DCO product.

The company also announced at ECOC the availability of a portfolio of single-mode lasers that operate over an extended temperature range.

“We see two new laser opportunities for us,” says LeMaitre. “The upgrade of the access networks and, concurrently, the deployment of 5G.”

Pilot Photonics makes a one terabit coherent comb source

Pilot Photonics has produced a four-wavelength laser chip for one-terabit coherent transmissions. 

It is one of several applications the Irish start-up is pursuing using its optical comb source that produces multiple tunable outputs, the equivalent of a laser array.   

The company is using its laser technology and photonic integration expertise to address Next Generation Passive Optical Network 2 (NG-PON2), coherent long-haul transmission, and non-telecom applications such as Light Detection and Ranging (LiDAR) and sensing.

“We have a number of chips reaching maturity and we are transitioning from an R&D-focussed company to early commercial activity,” says Frank Smyth, CEO of Pilot Photonics.

Finisar demonstrates its first silicon photonics transceiver

• Finisar unveiled its first silicon photonics-based product, a 400-gigabit QSFP-DD DR4 module, at the recent ECOC event.

• The company also showed transceiver technology that simplifies the setting up of dense wavelength-division multiplexing (DWDM) links.

• Two 200-gigabit QSFP56 client-side modules and an extended reach 30km 400-gigabit eLR8 were also demonstrated by Finisar. 

• A 64-gigabaud integrated tunable transmitter and receiver assembly (ITTRA) was used to send a 400-gigabit coherent wavelength.  

Finisar is bringing to market its first silicon photonics-based optical module. 

Christian UrricarietThe 400GBASE-DR4 is an IEEE 500m-reach 400-gigabit parallel fibre standard based on four fibres, each carrying a 100-gigabit 4-level pulse amplitude modulation (PAM-4) signal. Finisar’s DR4 is integrated into a QSFP-DD module. 

“The DR4 is the 400-gigabit interface that most of the hyperscale cloud players are interested in first,” says Christian Urricariet, senior director of global marketing at Finisar.

The company demonstrated the module at the recent European Conference on Optical Communication (ECOC), held in Rome.

Ciena to sell its own coherent modules

The systems vendor is expanding its offerings to include WaveLogic modem chips and coherent optical modules.

Ciena is developing its own coherent modules to sell to the telecom and datacom markets. 

The system vendor has set up the Optical Microsystems Division business unit to promote its WaveLogic coherent modem technology to the marketplace. Until now it has licensed its WaveLogic Ai digital signal processor (DSP) to module makers Lumentum, NeoPhotonics and Oclaro. But now it is planning to sell its own coherent modules.

In a job advert for a head of sales channel development, Ciena says the Optical Microsystems Division's goal is ‘to develop and productize electro-optic components and modules for sale to global systems integrator customers to be incorporated in their products for sale to telecom and data network customers’.

And at the recent European Conference on Optical Communication (ECOC) held in Rome, a network equipment manufacturer said it was approached by Ciena enquiring if it was interested in buying coherent modules from the company.
