Plastic and PCF fiber-optic cables
Plastic and PCF fiber-optic cables
Plastic (POF) and PCF fiber-optic cables are used for the connection of Optical Link modules
with connections for plastic fiber-optic cables (OLM/P), Optical Bus Terminal (OBT) and
devices with integrated optical interfaces. Under certain conditions, they are an inexpensive
alternative to conventional glass fiber-optic cables.
Plastic Fiber Optic duplex core
The plastic fiber-optic duplex core is a flat dual core with PVC inner jacket without protective
jacket. The cable can be easily assembled on-site.
The cable is intended for indoor applications with low mechanical loads or inside cabinets.
For OLM connections and with integrated optical interfaces you cover a length of up to 50 m
between two devices with this cable.
Plastic Fiber Optic standard cable
The plastic fiber optic standard cable consists of two plastic fibers with robust polyamide
inner jacket surrounded by Kevlar tensile elements and a purple PVC protective jacket. The
cable can be easily assembled on-site.
The robust round cable is suited for indoor applications. The maximum distance that can be
covered is 80 m for OLM/P connections and 50 m with integrated optical interfaces and OBT.
PCF Standard Cable
The pre-assembled PCF Standard Cable consists of two PCF fibers surrounded by Kevlar
tensile elements and a purple PVC protective jacket. It is always supplied with a pulling aid
installed on one end to pull in the cable channels.
The robust round cable is suited for indoor applications with cable lengths up to 400 m
(OLM) or 300 m (integrated optical interfaces, OBT) between two devices.
PCF Standard Cable GP
The PCF Standard Cable GP consists of two PCF fibers surrounded by Aramid tensile
elements and a green PVC protective jacket. The cable is pre-assembled and can be
ordered by the meter. It is supplied with a pulling aid installed on one end to pull in the cable
channels.
The robust round cable is suited for indoor and outdoor applications with cable lengths up to
400 m (OLM) or 300 m (integrated optical interfaces, OBT) between two devices.
