Profile: Fibrefab Ltd. manufactures a wide range of fibre components, modules and solutions designed for telecommunication industry. Multimode to singlemode converters provide solutions for interconnecting multimode fiber LANs over longer distances by integrating singlemode fibre optic cable into the LAN. The converter also enables ethernet LAN and WAN connectivity, by providing a multimode interface to singlemode fibre carrier demarcation points. Models are available for singlemode to multimode conversion between fast ethernet devices, or for asynchronous transfer mode (ATM) applications transported over a synchronous optical network (SONET). Each media converter is enclosed in a compact, strong metal case and includes an external power supply for stand-alone applications. We provide 2-12 fibre fire survivablity double jacket cable with metalic armouring and strength members. It is extremely rugged 2-12 fibre indoor/outdoor fire survivability cable consisting of a stainless steel gel filled loose tube, LSZH low smoke zero halogen inner jacket with stranded steel strength members. Corrugated steel tape armouring and LSZH final jacket for enhanced fire resistance.
