One Product features of single and multi-mode converters:
Our company has launched a series of "optical electric optical" active fiber mode converters suitable for telecommunications applications based on years of service experience in the telecommunications industry. Its specific types include:
1) Wavelength converter - provides optical wave conversion and amplification between 1310nm<->1550nm, 1310nm<->850nm, and 850nm<->1550nm. This device can also be used as an active optical amplifier.
2) Mode converter - provides conversion between 850nm and 1310nm multimode optical signals and 1310nm and 1550nm single-mode optical signals. This device can also be used as an active optical amplifier.
3) Single fiber to dual fiber "converter - provides conversion between dual fiber signals of various modes (single/multi-mode) and wavelengths (850nm/1310nm/1550nm) and single fiber signals of wavelength division multiplexing, where the single fiber signal can be further divided into multi-mode optical signals of 780nm/850nm and single-mode optical signals of 1310nm/1550nm.
Our company provides devices with different speeds of 155M, 622M, and 1.25G to meet the needs of operators to the maximum extent possible. Fiber optic mode converters are suitable for single-mode/multi-mode fiber optic data transmission networks with speeds of 155M/622M/1.25G. After conversion/amplification, the maximum transmission distance of the optical signal can reach 120 kilometers. This device is compatible with the vast majority of communication technologies, including Etherent, Token Ring, PABX, OC1/OC3, ATM, FDDI, and SONET.

II Appearance description of single/multi-mode converter:
The mode converter has 4 indicator lights:
PWR: The indicator light is on, indicating that the power is connected and the power supply is normal
FIBERA: When the indicator light is on, it indicates that the single-mode fiber receiving port is connected correctly, and the indicator light is on when the single-mode light receiving intensity is sufficient; When the light is not on, the communication connection cannot be established
FIBERB: When the indicator light is on, it indicates that the multimode fiber receiving port is connected correctly, and the indicator light is on when the multimode light receiving intensity is sufficient; When the light is not on, the communication connection cannot be established
FiberA: (single-mode optical interface) connected to single-mode optical fiber
Fiber B: (multimode optical interface) connected to multimode optical fiber
