This Telephony article details the series of recent announcements by the Competitive Local Exchange Carriers (CLECs) to increase their buildouts of metro fiber netrworks. According to the article increase in demand by customers is only an indirect reason for the buildout. Also: “The loss of [unbundled network element platforms] means that telecom players need local access alternatives to the Bells. In addition to UNE-P replacement, the [voice-over-IP] substitution for the [public switched telephone network] and other drivers of data for every business are driving those fiber investments in many cities.” Filed under: Uncategorized and Fiber Optic Cable Network Upgrades Comments: None |

This Lightreading article details the growing popularity of the Ciena CN 4200 DWDM platform among cable TV operators (MSOs). In addition the 4200 has sold well with the telephone companies since its introduction in 2005. According to the article, the primary differentiator is the universal line cards: The 4200’s line cards can be programmed to support different data services including Fast Ethernet, 10-Gbit/s Ethernet, OC3, OC192, Fibre Channel, and Escon, Auster says. Most of Ciena’s competitors, he says, require separate cards for each service. According to the comments, Meriton has a similar capability but apparently Ciena has a larger mindshare.

TDC Song has signed an agreement with SUNET for the supply of dark fibre for building the next generation of university network. The agreement runs for 8.5 years, at a value of SEK 235 million. SUNET (Swedish University Computer Network) is the network that links together all Swedish colleges and universities, along with a dozen museums and certain other external organisations, including The Swedish National Agency for Higher Education. This is one of the world’s most powerful university networks and can handle speeds of 2.5 Gbit/s per university. The network is now being updated to become the next generation university computer network, with speeds of up to 40 Gbit/s per university. Filed under: Uncategorized Comments: None |

In addition to the general difficulty of miniaturizing optical transceiver units, commercializing an XFP optical transceiver with DWDM specifications has previously been an insurmountable challenge. Fujitsu Limited and Fujitsu Laboratories have now solved this problem by their successful development of three key technological innovations: 1. An original, compact transceiver circuit; 2. A low-power-consuming optical device and high-efficiency heat dissipation mechanism; 3. High-frequency/high-density mounting technology.

Recently Philippe Morin, general manager of Nortel’s optical business, made the following statement: -On Infinera recently claiming leadership in the 10-Gb/s optical market: Actually, 10-Gb/s ports is where they believe they’re No. 1. When you put regens everywhere, you will have a lot more 10-Gb/s ports than competitors that do not put regens everywhere. We believe the way to go forward is to simplify the offering as much as we can. Infinera is going the opposite way, putting regens every 80 km. We’re trying to get rid of regens, to simplify the network and have DWDM capabilities. Drew Perkins, Infinera CEO replied: I think Philippe is trying to spread fear, uncertainty and doubt. That’s poppycock. We enable customers to have add/drops every 80 km or less because we can cost-effectively do that, whereas most vendors cannot. We regularly have customers deploying it at kilometers and tens of kilometers between add/drop sites. However, we have customers that deploy our equipment 500 or 600 km between regen[erator]s or add/drops or any electronic sites. Any comments? Filed under: Uncategorized Comments: None |

Infinera has acquired Big Bear Networks’ electronic dispersion compensation assets, including intellectual property, for telecommunications networks. Infinera already uses Big Bear’s electronic dispersion compensation solutions in the Infinera DTN system…Future versions of Big Bear’s dispersion compensation solutions will be developed at Infinera and integrated into Infinera ASICs. From LightReading: Infinera will not sell Big Bear’s chips to other companies, Welch says. So whoever else was using the Big Bear dispersion compensation chips must now look for alternate suppliers.

This article in Lightwave describes the technology behind and applications of directly modulated chirp managed lasers. The authors are Daniel Mahgerefteh and Frank Fan. The advantage of these devices is that transmission distances of up to 250 km can be reached without regeneration and/or external modulation. According to the authors, this is an increase from 10 km with previous designs. Filed under: Uncategorized and Fiber Optic Components Comments: None |
