Converged Fibre - Ethernet

XCELTRA: Smart Fiber Solution is honored to introduce Smart Office concept. Besides increased security and energy efficiency,Smart Office solutions offer considerably more convenience than conventional solutions through a powerful programming interface that allows the installation of additional programs (Apps) with intelligent functions in the network. Application specific extensions are installed simple and quick and offer additional benefits.

Users can adjust their work environments to suit their personal needs in an easy, flexible and economical way.
A solution based on decentralized control does not require any additional, labor-intensive control and no additional server. The decentralized approach furthermore allows a step-by-step implementation, “office by office”.
Another plus: Even when the central system fails, the independent local control remains unaffected.

FTTO Solution:

Fiber To The Office (FTTO) is a standard compliant and decentralized cabling concept for modern office environments.
It combines the advantages of highly efficient fiber optic technology with the flexibility of twisted pair cabling.
In contrast to the established structured cabling network (SCN), FTTO additionally employs future-proof fiber optic cables for riser cabling and horizontal wiring.
Copper cabling only comes to play to connect terminal equipment like workstations, VoIP-Phones or IP-cameras.
As a result, the MICROSENS FTTO switches offer rich power management functions like Power-over-Ethernet and energy efficient Ethernet.
With Fiber To The Office, enterprises profit from a highly cost effective networking infrastructure that offers flexibility, protects investments and reduces life cycle costs.


Customer specific access/blocking of all resources at the work place

Energy Efficiency
Monitoring and optimization of the energy consumption, e.g. disabling of unused functions

Easy configuration and administration, high level of automation

Attractive and stylish design for various operational areas

Within modern office environments, conventional structured cabling reaches closer and closer to its limits. This results from strict range limitations and increasing bandwidths demands by the users. The implementation of cost-reducing technologies such as virtualized desktops and Voice over IP requires high bandwidth and low latency to ensure a positiveuser experience. Because of the collapsed backbone architecture, Fiber To The Office delivers more effective bandwidth to the user than a commonly used star-shaped net work, allowing an highly efficient working environment.

In view of the rapid development and dynamic increase of IP applications, the question is raised whether POL will stay competitive with regard to applications with the decision in favor of POL; the user is bound to this special technology. The FTTO infrastructure, in contrast, is completely application-neutral and therefore future-proof

The total costs (first installation, operation, planned replacements) of the copper architecture are in all scenarios higher than the FTTO solution and the cost advantage increases if you increase the distances, the number of floors or the number of workspaces.

Project Summary:
MICROSENS switches used to create a high-performance fiber optic network in the international airport’s new eleven-storey Concourse A terminal building. The MICROSENS Fiber To The Office (FTTO) concept was employed in an area more than 500,000 square meters; the components’ special design made an intelligent combination of fiber optic and copper connection technologies possible. The MICROSENS technology met the considerable challenge of supplying the approximately 50 ticket and check-in desks, hotels, and businesses with high-performance data transmission. These standards also apply to the new building’s 20 gates, most of which are set up to manage the Airbus 380—currently the largest aircraft in civil aviation. MICROSENS’ FTTO technology guarantees the high bandwidth needed over large transmission distances, while also meeting the airport’s high standards in terms of both data security and energy efficiency.

• As a core router they used the Cisco ASR9010.
• As aggregation switch the Cisco Catalyst 6509E
• As access switch the FTTO switches.

To manage the FTTO switches they use Microsens nmp server software.

After some years now they just implement the HP NNMi software as an umbrella management.

In this umbrella management they integrate all networking equipment including the Cisco devices and our FTTO switches. To integrate the FTTO switches they use SNMP v 2c.

Feature-wise they just use the PoE functionality and the VLAN functionality on our switches.

Solution Advantages
Financial considerations were another key factor in the decision to install a fiber optic network using MICROSENS switches:
• Reduce the number of distribution rooms needed significant compared to exclusively copper-based cabling and network technologies.
• This increases the amount of usable space available to businesses and airport management in the new building.
• The FTTO concept helps reduce the overall costs of purchasing, installing, and maintaining cabling technology and intermediate distributors.
• The MICROSENS concept contributes to a significant reduction of IT-related operational and energy costs, since the decentralized approach makes air conditioning and uninterrupted power supply (UPS) equipment largely unnecessary.
• MICROSENS’ FTTO concept is well prepared for future-proof networking technologies that can be adapted to suit new requirements easily and cost-efficiently the system can be upgraded to new technologies by simply exchanging active network components, and passive cabling can remain in place during expansions.

The FTTO (Fiber-to- the-Office) concept offers the optimum IT solution with maximum network service availability, and minimized downtime for your office building……

Smart Office Concept
For a long time, switches were nothing but traffic nodes within a network. They distributed data streams, but could not take over any complex control tasks. Because of that, they only played a minor role in premises automation. Technology specialist MICROSENS proves that this must not necessarily be the case. Further developed as intelligent network components, the micro switches of MICROSENS take over the functions of classic control centers and, thus, help to decrease investment costs and offer more convenience to the user. According to the individual configuration, they e.g. control the heating and ventilation, as well as the lighting. Here, they process the incoming information about the current light conditions and adapt the strength of the illumination and the colour of the light on the basis of the user specifications. The decentralized positioning of the micro switches additionally minimizes the risk of being a single point of failure: In contrast to centralized control systems, the outage of a switch will not cause the complete smart office structure to break down.

The MICROSENS FTTO concept is based on the dimensions of 45 x 45 mm (system 45 x 45). This is a widespread design throughout the world that facilitates the use in national and international installation systems. Popular areas in addition to the standard installation in wall trunking systems and under floor systems are table and laboratory equipment as well as pillars in rooms and flush-mounted installations.
