Ciena enhances its 6500 packet-optical transport family

Ciena has upgraded its 6500 family of packet-optical transport platforms with the T-series that supports higher-capacity electrical and optical switching and higher-speed line cards.

"The 6500 T-Series is a big deal as Ciena can offer two different systems depending on what the customer is looking for," says Andrew Schmitt, founder and principal analyst of market research firm, Cignal AI.

 

Helen XenosIf customers want straightforward transport and the ability to reach a number of different distances, there is the existing 6500 S-series, says Schmitt. The T-series is a system specifically for metro-regional networks that can accommodate multiple traffic types – OTN or packet.

"It has very high density for a packet-optical system and offers pay-as-you-grow with CFP2-ACO [coherent pluggable] modules," says Schmitt.

Ciena says the T-series has been developed to address new connectivity requirements service providers face. Content is being shifted to the metro to improve the quality of experience for end users and reduce capacity on backbone networks. Such user consumption of content is one factor accounting for the strong annual 40 percent growth in metro traffic.

OFC 2016: a sample of the technical paper highlights

Optical transmission technologies, Flexible Ethernet, software-defined networking, CFP2-ACOs and silicon photonics are just some of the topics at this year's OFC 2016 conference to be held in Anaheim, California between March 20th and 24th. 

Here is a small sample of the technical paper highlights being presented at the conference.


Doubling core network capacity 

Microsoft has conducted a study measuring the performance of its North American core backbone network to determine how the use of bandwidth-variable transceivers (BVTs) could boost capacity.

The highest capacity modulation scheme suited for each link from the choice of polarisation-multiplexed, quadrature phase-shift keying (PM-QPSK), polarisation-multiplexed, 8 quadrature amplitude modulation (PM-8QAM) and PM-16QAM can then be used.

100 gigabit the next stop on PON's roadmap 

A Q&A with Frank Effenberger, vice president of the Fixed Access Network Laboratory at Futurewei Technologies, the US subsidiary of Huawei. Effenberger is also rapporteur of the ITU-T Q2/15 group that standardises optical access.

Q. What are the various ways the industry is considering implementing 100 Gigabit? 

FE: The work happening now is to do a 25 gigabit-per-second wavelength, and then multiple wavelengths will be combined in some way to create 50-gigabit or 100-gigabit speed offerings.

Next-generation coherent adds sub-carriers to capabilities

Briefing: DWDM developments

Part 2: Infinera's coherent toolkit 


Source: Infinera

Infinera has detailed coherent technology enhancements implemented using its latest-generation optical transmission technology. The system vendor is still to launch its newest  photonic integrated circuit (PIC) and FlexCoherent DSP-ASIC but has detailed features the CMOS and indium phosphide ICs support.

The techniques highlight the increasing sophistication of coherent technology and an ever tighter coupling between electronics and photonics.
