Mr Henry Thai
    Kocent Optec Limited is our long-term partner. In 8 years of co-operation times we together win many projects. Their fast connector and FTTH drop cable quality are best. Their products are cover my country now.
    Mr Pablo
    I was surprised when i made first order with Kocent Optec Limited in 2014. One container 40GP of GYXTW cable and one container 20GP for fast connector, patch cord and adapter. They finished this order in 2 weeks only. Now we also purchase many type of FDB box and Splice Closure Box from them. Hope we will be stronger and stronger in telecom field.

Product Description


Female to Make E 2000 3dB 5dB Attenuator / E2K UPC Fibra Optica Attenuator / Plug-in Fixed Attenuator



- We supply various kinds of fiber attenuators, including LC, SC, and ST, FC, MU, MPO, E2000 and Variable fiber optic attenuators.

- An optical attenuator uses a segment of attenuating fiber interposed in the optical path.

- The attenuating fiber is produced by using a solution doping technique to introduce transition or rare earth elements into the fiber's core.

- The dopant reduces the transmission of the fiber.

- The degree of attenuation depends upon the material used as the dopant, the dopant level, and the length of the attenuation segment.

- In a specific embodiment, an optical attenuator is provided having a first and second signal carrying optical fibers and an attenuating fiber segment, each of which has a core, a cladding substantially coaxial with the core, and a substantially planar end face. The attenuating fiber segment is fusion spliced between the first and second signal carrying optical fibers.

- In a second embodiment a portion of the cladding of the attenuating fiber is chemically etched.

- E2000 fiber optic attenuator includes E2000 single mode female to female fiber optic attenuator from 1dB to 30dB

- Use to connect E2000 fiber optic pigtail or patch cables to reduce the power of signal at a certain attenuation.

- E2000 fiber optic attenuator is a passive device used to reduce the amplitude of a light signal without significantly changing the wave form itself.

- This is often a requirement in Dense Wave Division Multiplexing(DWDM) and Erbium Doped Fiber Amplifier (EDFA) applications where the receiver can’t accept the signal generated from a high-power light source.

- Metal ion doped fiber
- High-power light source durability
- 1310nm, 1550nm, 1250-1625nm and 1350/1550nm dual wave lengths
- Wavelength independence
- Attenuation levels ranging from 1dB to 30dB, with standard and premium tolerances, plus custom configurations.


- Dense Wave Division Multiplexers (DWDM).

- Erbium Doped Fiber Amplifiers (EDFA).

- Fiber optic communication systems.

- Overpowered fiber optic systems.

- Fiber optic CATV.

- Fiber optic test.
