FiberMultiplier – more effective utilization of fiber

Muenster, March 12th 2003 – Communication by light – Gesellschaft für optische Kommunikationssysteme mbH (CBL) presents from March 12th to19th at the CeBIT in hall 14 booth J42 its high scaleable FiberMultiplier family. Actual highlights from this family are the Coarse Wavelength Division Multiplexers (CWDM) with four and eight channels. Up to eight independent channels can transmit different signals simultaneously over only one pair of fiber. With its modular system-design the FiberMultiplier can be customized individually to the client’s demands. The management takes place web-based or via Simple Network Management Protocol (SNMP)–agent. It observes a multitude of parameters and diagnostic functions as well as the power level of the incoming signals during operation. With interface adoption of once purchased modules as well as soft- and firmware upgrades CBL offers its customers a high investment protection.

FiberMultiplier for solutions with high demand of bandwidth

FiberMultiplier offer a more effective utilization of existing fiber lines (”dark fiber“). Different applications can be transferred at the same time over up to eight independent channels via only one pair of fiber. The desired fiber interface at the network side is selectable individually for each channel whereby all current multi and single mode interfaces are available.

One pair of fiber transmits up to eight different applications

The FiberMultiplier transmits applications in wavelength ranges between 1470 and 1610 nm over one pair of fiber. Each single channel can transmit a maximum data rate of 1250 Mbps over distances of up to 30 km. At this speed and bandwidth the FiberMultiplier is suitable especially for fast growing networks.

The SNMP compatible web-based management system controls continously all relevant parameters for operation. Even the power level of the incoming signals of the link line can be observed during current operation. Defining thresholds the extensive diagnostic functions allow to recognize slow changes at an early stage allowing to arrange suitable support procedures. In case of failure they help to assign spare parts in the forefront to reduce maintenance and personnel expenses. The user receives a clearly arranged graphical display of all connections and an intuitive user interface.

FiberMultiplier offers customized solutions

The modular system design of the FiberMultiplier fits the individual customer requirements. The CBL product range involves three different housings with one, three or four height units, modules for different distances and bandwidths as well as various transmission wavelengths. The user starts with a network interface and the 4-channel multiplex-/demultiplex-unit and purchases suitable modules at a future date depending on requirements and application. If four channels are not sufficient any more up to eight channels may be added by simply replacing the multiplex-/demultiplex-unit. The interface modules to the network and already existing management modules are not affected hereby.

The housings fit in a 19“ rack. The 4-channel CWDM4 solution requires four height units. The passive multiplexer unit is supplied in an own 1 U height frame or as a plug-in module for the housings. The 8-channel CWDM8 solution will be delivered with a 4 U height housing which can accept up to 16 modules for two 8-channel transmissions. A 1 U height frame admits the passive multiplexer plug-in modules.

Investment protections at all channels

CBL offers to customers the possibility of a cost-effective changeover for instance fo a replacement of the user interface from multi to single mode. Furthermore firmware upgrades for the management module make sure that the management software is always at state-of-the-art and the functions will be permanentely extended and improved.
