CVD-08 preform fabrication system is based on versatile and flexible MCVD preform technology. It is suitable for fabrication of wide range of optical fiber preforms and can be combined with a number of add-on devices for special doping (rare earth vapor phase precursor delivery) or advanced processing (FCVD) using a furnace instead of oxyhydrogen burner as heat source. CVD-08 is adapted to specific customer requirements and is available in different equipment configurations depending on application.

GWL-10 glass working lathes in different configurations and sizes are used in substrate tube preparation, welding, stubbing, preform polishing, jacketing and stretching of quartz glass. They are often used for rounding asymmetrically shaped preforms and in preparation of micro-structured preforms for drawing.

VSL-11 vertical glass working lathe is developed for jacketing preforms in vertical position, or for stretching preforms and tubes. As vertical has specific advantages over horizontal jacketing when very precise core concentricity is required, it is strongly suggested in fabrication of polarization maintaining fiber preforms, as well as in fabrication of low birefringence preforms.

MCF-35 MCVD furnace is a powerful, symmetrical and accurately adjustable heat source developed for advanced MCVD process. It reduces influence of asymmetric burner flame on final preform geometry while shortening fabrication time significantly, thus limiting the OH- diffusion for reduced water peak.

SBL-22 Automatic soot removal and substrate tube inner pressure control system is made of materials resistant to rust by chlorine and high temperature gases (SS, PVC) and exposed metal surfaces are painted with anti-rust paint. The box is installed inside tailstock bore. At one end (inside) it provides sealing to exhaust (soot collection tube), and on the other (outside) to non-rotating support for soot remover and for connections to: scrubber exhaust, pressurizing gas for tube inner pressure control and pressure sensor.

Soot box SBL-22 is suitable for industrial environment and is based on an industrial standard solution, used by
large fiber-makers. This box is used when tube diameter control is required.

BRC-12 Optacore’s Bubbler refill cabinet for MCVD preform making equipment refilling is a specially constructed set of cabinets (individual cabinets for each reagent), each with space for one delivery container and one intermediate refill container. Cabinets are constructed for refilling bubblers with SiCl4 and GeCl4.

MSC-09 scrubber is a professional system for disposal of gas pollutants by washing effluent gases from MCVD preform fabrication process and quartz tube washer/etcher. By its size and purification capacity it can be adapted to the number of installed machines at customer’s site. Largest MSC scrubber units can wash up to 3000 Nm3/h of effluent gases, and the smallest unit (MSC-09/S is intended for laboratories with a single deposition system.

SGC-13 Gas Cylinder Cabinets is supplied to be used together with MCVD equipment, providing all essential functions and compliance with safety principles of operation. Safe connection and use of special gases is extremely important in optical fiber preform fabrication process, both for gas purity, as well as safety of equipment and personnel. Some gases used in MCVD process are very aggressive or even toxic, therefore proper handling during cylinder connection and exchange has to be provided.
