Wirewerks fiber optic patch cords and pigtails are the ideal medium to interconnect or cross-connect optical networks within a structured cabling system and test and measurement applications. They are designed, manufactured and tested in compliance with Telcordia, ANSI/ TIA and IEC industry standards. The quality of the components used to build Wirewerks fiber optic patch cords and pigtails ensures reliable connections. They are available in a wide variety of connector options, cable constructions and flammability ratings. Our fiber factory has the ability and expertise to customize the assembly to meet the most stringent mechanical and optical performance specifications. All Wirewerks' patch cords and pigtails are assigned a serial number and identification label. The information appearing on these labels consist of the part number, product description, serial number, guaranteed insertion and return loss (return loss for single mode patch cords and pigtails) and length of the patch cord or pigtail are displayed for easy product recognition and traceability.
