A fixed attenuator is a precision optical device with a fixed amount of fiber attenuation. The attenuation of optical power is achieved according to the pre-designed attenuation of the line. Products are used in a variety of fiber optic transmission lines.

Key features

• The fiber attenuator test system has the characteristics of high attenuation precision, low additional loss and good stability.
• Main fiber optic communication systems; fiber optic CATV; high power optical device measurement; It is used to attenuate the input optical power and avoid the distortion caused by the optical receiver due to the strong input optical power.
• Product classification Flange type fixed attenuators: FC type, SC type, LC type, etc.; attenuation amount: 3, 5, 7, 10, 15dB and other grades. Yin-yang fixed attenuators: FC type, SC type, LC type, etc.; attenuation amount: 3, 5, 7, 10, 15dB and other grades.
• Attenuation accuracy: ±10% Working wavelength: 1310 and 1550 Return loss: ≥50dB (PC), ≥60dB (APC) Working temperature: -40~+85 °C.

Application scope

• Fiber to the home (FTTH) projects
• Cable network TV (CATV)
• Passive optical network systems (EPON / BPON / GPON)
• Other optical splitting systems
• Local area networks (LAN) and access networks
• Metropolitan area networks (MAN)
