Fiber optic cable patch cord is the most commonly used product in low-voltage projects. It functions as guiding light signals to their destination equipment and enabling the conversion between optical and electrical signals.
Understanding the key factors when selecting fiber optic cable patch cords is crucial for optimal performance and reliability.
1. Aina za Kiunganishi
Viunganishi tofauti vinafaa kwa vifaa tofauti, huku aina kuu zikiwa ni MPO, SC, FC, LC, na st.
- Kamba za kiraka za MPO: Inatumika kwa 40G, 100Moduli za macho za G na vituo vya data vyenye msongamano mkubwa
- Kamba za kiraka za LC: Inatumika kwa kuunganisha moduli za macho za SFP, iliyo na jeki za kawaida, kawaida hupatikana kwenye ruta
- Kamba za kiraka za SC: Unganisha moduli za macho za GBIC, with a rectangular housing and a plug-and-play locking mechanism, hutumiwa mara kwa mara kwenye ruta na swichi
- Kamba za kiraka za FC: Feature a metal sleeve for external reinforcement and a screw-lock fastening method, mara nyingi hutumiwa katika paneli za kiraka
- Kamba za kiraka za ST: Have a circular housing and a screw-lock fastening method, kawaida kutumika katika paneli kiraka
2. Aina za Fiber
Single-mode fiber optic patch cords use 9/125um fibers, while multi-mode fiber optic patch cords use 50/125um or 62.5/125um fibers.
They are primarily used for long-distance data transmission, while multi-mode fiber optic patch cords are used for short-distance transmission.
Single-mode fiber optic patch cords typically have a yellow jacket, while multi-mode fiber optic patch cords come in OM2 (machungwa), OM3 (maji), OM4 (urujuani), na OM5 (chokaa kijani).
3. Mbinu za Usafishaji wa Kiunganisha
Different polishing methods determine the quality of fiber optic transmission. Viunganishi vya PC/UPC ni bluu, wakati viunganishi vya APC ni kijani.
- Kompyuta (Mawasiliano ya Kimwili): polishing ndogo-spherical, reducing air gaps between fiber optic components and achieving physical contact between fiber ends
- UPC (Mawasiliano ya Kimwili ya Juu): Further optimized polishing and surface finish based on PC, with a slightly domed end face for more precise mating
- APC (Mawasiliano ya Kimwili ya Angled): Fiber end face is typically polished at an 8° angle, providing tighter fiber end face contact and reflecting light through the angle into the cladding instead of directly back to the source, kutoa utendaji bora wa muunganisho
Hasara ya kawaida ya kuingiza kwa PC, UPC, na viunganishi vya APC ni chini ya 0.3dB, with UPC/PC achieving lower insertion loss due to smaller air gaps. Upotezaji wa kurudi kwa PC ni -45dB, Hasara ya kurudi kwa UPC kwa ujumla ni -50dB (au juu zaidi), and the industry standard for APC return loss is -60dB.
4. Nyenzo za Jacket ya Kamba
Common fiber optic patch cord jacket materials include PVC and LSZH.
- PVC (Kloridi ya polyvinyl): Inaweza kuwaka na hutoa gesi zenye sumu, haifai kwa matumizi ya ndani, gharama nafuu
- LSZH (Moshi wa Chini Zero Halojeni): Rafiki wa mazingira na isiyozuia moto, lakini ghali zaidi
If you need to purchase fiber optic cable patch cord, Fibconet, kama a Huawei Mini Patanifu Sc/APC Simplex Kiunganishi kisicho na maji cha Ipscapc na karibu 20 miaka ya uzoefu wa uzalishaji, can meet your customization needs and provide insertion losses as low as 0.1dB.
