In scenarios such as ocean exploration, underwater robot ROVs, underwater monitoring base stations, and underwater camera systems, stable signal transmission is the core prerequisite for operations. Ordinary fiber optic connectors are afraid of seawater erosion and water pressure impact, which can easily lead to signal interruption, excessive loss, and other problems. The single optical single-mode watertight connector is a special connection device specially designed for underwater fiber optic communication.
Single optical single mode water tight connector, as the name suggests, integrates a single single mode fiber optic path internally and is equipped with a precision water tight sealing structure. It belongs to the category of optoelectronic underwater connectors. Single mode fiber itself has the advantages of long transmission distance, high bandwidth, and low signal dispersion, making it suitable for long-distance underwater signal transmission; After being equipped with an integrated waterproof design, it can isolate seawater infiltration in soaking environments, protecting the fiber optic end face from corrosion and damage caused by seawater, sediment, and microorganisms.
Compared with multi mode watertight connectors, the single optical single mode model is more suitable for long-distance transmission scenarios: multi mode is mostly used for short distance signal transmission within tens of meters, while single mode optical paths can support underwater communication at the level of several kilometers, commonly used for transmitting high-definition videos, sensor data, and control commands. Compared with the optoelectronic composite waterproof connector, the pure single optical single mode style has a simplified structure, lighter weight, and smaller outer diameter, making it suitable for underwater equipment with compact space, only requiring fiber optic signals, and no synchronous power supply.
