Users of data-transmission systems (bus systems) with high data rates, long transmission distances, or strong electro-magnetic loads frequently rely on fiber-optic cables (FOC).
Many users are not yet aware that chainflex® fiber-optic cables for cable carriers offer more advantages than standard FOCs.
Copper-based data-transmission systems characterize themselves primarily through two basic disadvantages:
The maximum transmission distances are limited by the transmission systems (between 16 and 160 ft cable length).
2The copper-based cables used in cable carrier systems often display an increase in dampening values after a high number of cycles, which again has a negative effect on the maximum range.
Fiber optic cables made of glass and independent of data transmission and/or bus systems offer the following benefits:
Transmission distances are not limited by data transmission systems used and amount to - depending on the FOC type – a few thousand feet.
2Dampening increases are so low in chainflex® FO cables - even for very high numbers of cycles in cable carrier systems - that barely measurable values are ascertainable and the largest part of the dampening is located at the plug.
| Test cable: | igus® chainflex® CFLG.2HG.MF. 50/125 |
|---|---|
| Number of fibers: | 2 numbers |
| Fiber type: | Gradient fiber 50/125µm |
| Plug: | 2 x ST plug |
| Travel: | 6.6 ft (2 m) |
| Cable length: | 9.8 ft (3 m) |
| Energy chains: | igus® energy chain series 15.015.100.0 |
| Test radius: | 11 x d |
Allowing for an average insertion loss of 0.3 dB and a maximum of 0.5 dB for the ST plug, the dampening increase of about 0.1-0.15 dB after over 30 million movements in the cable carrier is completely negligible. The cable covered over 37,000 miles of travel in the test.
The fiber-optic wavelength considered here is 850 nm.
