2-core Mining Optical Cable, MGTS-2B, Mining Single-mode Fiber Cable
1. Divided according to the transmission medium characteristics within the optical cable - fiber optic (glass or plastic fiber) - into: Single-mode fiber optic and Multimode fiber optic.
2. Mining optical cables are further categorized based on the characteristics of the selected fiber, into single-mode optical cables and multimode optical cables.
3. Single-mode (B): Indicates that only one wavelength (frequency) is transmitted within the medium (typically silicon dioxide, or glass), through a conductor slightly thicker than a human hair (commonly referred to as glass fiber).
Crisp, brittle, and extremely strong (with a high tensile strength), it is nearly the opposite in mechanical properties to a hair strand. Due to inconsistencies in light transmission performance caused by the other components of the medium, single-mode fibers are further subdivided into:B1.1 (Non-dispersive Shift Single-mode Fiber ITU-T G652) and B4 (Non-zero Dispersive Shift Single-mode Fiber ITU-T G655), wavelengths typically used are 1310nm or 1550nm, with B1.1 being the primary single-mode fiber, sometimes simply referred to as "B" (non-standard terminology).
4. Multimode A1 (ITU-T G651): Indicates the medium (single-mode) can simultaneously transmit multiple wavelengths (frequencies). The multimode fiber, which is slightly thicker than a hair and commonly referred to as such, is further divided into A1a (50/125) and A1b (62.5/125), collectively known as ITU-T G651. The commonly used wavelengths are typically 1310nm or 850nm.
5. Fiber Optic Transmission Distance
Generally, single-mode transmission without relay can reach120km, multimode is 2km; 10/100/1000M optical signals typically reach 60-80km over single-mode without repeaters; multimode ranges from 500m to 50/125um; 200m to 62.5/125um. Therefore, multimode is generally used indoors or for patch cables, while single-mode is used outdoors for long-distance transmission.
