China Mobile Shangdong Branch (Shangdong Mobile) deploy Huawei’s GPON fiber-to-wireless (FTTW) offering in 17 cities of Shandong province to backhaul wireless local area network (WLAN) data streams and help Shangdong Mobile provide 54-Mbps Internet access for 50,000 WLAN hotspots in schools, offices, transport hubs, hotels, leisure places, downtown areas, and residences.

The FTTW equipment will be deployed in Shangdong Mobile’s E2E mobile backhaul network, covering the optical line terminal (OLT) in the central office, the optical distribution network (ODN), and the optical access equipment for multi-dwelling units (MDUs).

The combination of WLAN and existing mobile communication networks provides high-speed mobile broadband access, says Huawei. This enables users to work away from their offices, browse websites, send and receive emails, watch online movies, and download large files on the fly.

Communications service provider XO Communications has begun rolling out 100-Gbps wavelengths on a U.S. nationwide fiber-optic backbone network using coherent-based technology from Nokia Siemens Networks. XO chose Nokia Siemens Networks’ technology over that of its other incumbent long-distance platform supplier, Infinera.

According to XO Senior Vice President and CTO Randy Niklas, the first-of-its-kind national network initially will see four to six wavelengths of 100-Gbps traffic traveling over previously unlit fiber. The routes will have the capacity to handle 96 wavelengths, either with newly installed Nokia Siemens Networks hiT7300 systems or, in the near-term future, upgrades to the hiT7300 platforms XO already had in its network.

The 100-Gbps wavelengths will derive from multiplexed 10-Gbps traffic, Niklas told Lightwave. However, conversations are already underway with wholesale and client service customers who might require 100-Gbps connections. Along these lines, XO has completed 100-Gbps interface certification on Cisco routers and is doing the same with Juniper Networks routers, Niklas added.

Niklas said that XO did not conduct an RFP for the backbone project, but turned to its incumbent suppliers. He said Nokia Siemens Networks was chosen because it could deliver 100-Gbps capabilities to XO’s amortization targets better than Infinera. “And we frankly got good business terms,” he added.

XO has partially completed the roll out, with work ongoing in its West Coast, Northeast corridor, and southwest territories. Meanwhile, the company has already turned its attention to shorter reach applications, thanks to interest from a major wireless carrier customer that wants 100-Gbps connectivity to its switching centers. To meet such requirements, XO also is certifying platforms from Ciena and Cisco for 100-Gbps performance.

This is the first announced 100-Gbps customer in North America, Jim Benson, head of Optical Networks for the Americas at Nokia Siemens Networks, confirmed. However, he indicated that XO isn’t the company’s only customer on the continent. Nokia Siemens Networks announced a pair of European 100G customers previously.

SomCable, a Somaliland-registered fiber-optic service provider, is deploying an IP over DWDM network using optical transport equipment from Optelian, the systems house says. The service provider, which is constructing the Berbera landing station that will connect Somaliland to submarine cable networks in the Red Sea, use Optelian’s LightGAIN system on a terrestrial backbone network.

“After exploring various network architectures, we converged on a next-generation IP over Dense Wave Division Multiplexing optical network to carry voice and data traffic throughout Somaliland and Optelian provides exactly what we are looking for,” explains Michael Cothill, CEO of SomCable. “With our aggressive plans to provision a new terrestrial backbone to transport all wireless and Internet traffic, SomCable needs an easy-to-use, reliable, and scalable solution that will allow us to start small and grow to meet our customers’ needs.”

“SomCable designed a state-of-the art next-generation network, so the advanced functionality along with the easy plug-and-play engineering of Optelian’s optical transport solutions serves them well,” states Mike Perry, president at Optelian. The LightGAIN system’s modular architecture and support for alien-wavelengths should prove particularly useful, Perry added.

Huawei, a leading global information and communications technology (ICT) solutions provider, today announced that it has been selected by Portuguese mobile operator Optimus to provide UMTS/LTE multi-frequency antennas for its LTE commercial network. The commercialisation of Huawei’s antennas in Portugal extends the current mobile network portfolio and will boost the overall prosperity of the European LTE market.

The coexistence of multi-format and multi-band technologies supporting GSM/UMTS/LTE networks has created great challenges for antenna deployment. With limited site space available, operators must choose multi-band antennas, which also provide efficient deployment and maintenance costs while meeting the technical requirements of the network rollout.

Using Huawei’s multi-band (1800MHz/2100MHz/2600MHz) antennas, Optimus added LTE operation while maintaining the number of antennas, minimising rental and infrastructure costs and retaining minimal visual impact. Tests on existing networks showed that Huawei’s antennas not only save on deployment and maintenance costs but also effectively improve the system throughput, capacity and overall network performance.
