Faced with a wide range of optical cable models such as GYTA, GYXTW, and GJFJV in the market, many enterprise procurement or operation and maintenance personnel often fall into the dilemma of selection. Wrong selection will not only cause budget overruns but also may lead to serious problems such as network performance bottlenecks and frequent outages. A factory once incorrectly used non-armored optical cables in a strong electromagnetic interference environment, resulting in intermittent control signals and an average of several hours of production downtime per month. In fact, the most expensive is not necessarily the most suitable. Mastering the following three expert tips can accurately match needs with optical cable models.
The first tip is to prioritize environmental adaptability, which is the cornerstone of selection. Outdoor overhead or pipeline environments need to cope with challenges such as mechanical stretching and moisture erosion, so GYTA or GYTS models are preferred; indoor wiring needs to balance flexibility and fire resistance, so GJFJV or flame-retardant GJFJZY are more suitable; for special industrial environments, it is recommended to upgrade to GYTA53 armored optical cables to enhance anti-interference and anti-rodent capabilities. Secondly, accurately interpret optical fiber parameters: single-mode optical fibers are suitable for long-distance and high-bandwidth scenarios, while multi-mode optical fibers are suitable for short-distance and low-cost connections, and the number of cores should be reserved with 30% redundancy. Finally, adopt a full-life-cycle cost perspective for evaluation to avoid only focusing on the purchase unit price while ignoring the later deployment and operation and maintenance costs.
Remember, the correct optical cable is the silent cornerstone of the network. The core of selection is not to pursue high-end, but to achieve precise matching of environment, needs and costs.
