Single-model fiber temperature measurement host

Product Overview

In the current conventional application scenarios, multimode fiber is primarily used for temperature sensing. However, in certain special fields, such as situations where single-mode fiber has already been installed on-site and cannot be replaced, or when the length of the fiber exceeds 20 km, it may be considered to use a single-mode fiber temperature sensing host. Single-mode fiber has a core diameter of 9 μm, which is nearly 7 times smaller than the 62.5 μm core diameter of multimode fiber. This results in lower optical power capacity and a poorer signal-to-noise ratio. However, single-mode fiber has low loss and can propagate over long distances with minimal loss. In certain special environments, it offers significant advantages for temperature sensing by utilizing regular communication fiber cables.

Our company has independently developed the DTS-BLY-5S (SMV), which features low power consumption of as low as 6W, a three-proof motherboard (anti-fungus, moisture-proof, and salt spray-proof), a temperature sensing distance of over 24 km, a maximum of 16 channels, compatibility with fiber cables up to 400 km in length, a minimum temperature sensing size of ±0.5 meters, positioning accuracy of ±0.5 meters, and temperature accuracy of ±1°C (measured data). In the case of shorter distances, such as lengths ranging from 2 km to 5 km, the measured temperature accuracy can reach ±0.5°C. The DTS-BLY-5S (SMV) demonstrates a balanced performance in terms of temperature accuracy, positioning accuracy, and measurement distance under single-mode fiber temperature sensing conditions. It is suitable for direct measurement in single-mode fiber environments of communication cables, submarine cables, data centers, and other applications.

Basic Information:

The single-mode DTS-BLY-5S(SMV) fiber temperature sensing host is a device that can transform a 400km 9um single-mode fiber cable into 4 million distributed fiber temperature sensors with positioning functionality.

In the current conventional applications, temperature sensing using multimode fibers is predominant. However, in certain special fields, such as environments where single-mode fibers are already installed and cannot be replaced, or situations where the fiber length exceeds 20km, it is worth considering the use of a single-mode fiber temperature sensing host. Single-mode fibers have a core diameter of 9um, which is nearly 7 times smaller than the 62.5um diameter of multimode fibers, resulting in lower capacity to carry optical energy and a poorer signal-to-noise ratio. However, single-mode fibers have low loss and can propagate over long distances with minimal attenuation. In certain special environments, it is advantageous to utilize standard communication fiber cables for temperature sensing.

The independently developed DTS-BLY-5S(SMV) from our company is a low-power device with power consumption as low as 6W. It features a motherboard with three-proof capabilities (anti-fungal, moisture-proof, and salt spray-proof), a temperature sensing distance of over 24km, a maximum of 16 channels, compatibility with up to 400km of fiber cable, a minimum sensing length of ±0.5 meters, positioning accuracy of ±0.5 meters, and temperature accuracy of ±1℃ (measured values). In short-distance scenarios, such as lengths between 2km and 5km, the measured temperature accuracy can reach ±0.5℃. The DTS-BLY-5S(SMV), when used for single-mode fiber temperature sensing, demonstrates a balance between temperature accuracy, positioning accuracy, and measurement distance. It is suitable for direct measurement in single-mode fiber environments of communication cables and finds wide applications in submarine cables, communication cables, data centers, and other single-mode fiber environments.
