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 Femal Fiber Optic Attenuator E2K APC UPC / E 2000 Adapter Attenuator 3dB 5dB 8dB



- E2000 is one of the few fiber optic connectors featuring a spring-loaded shutter which fully protects the ferrule from dust and scratches.

- E2000 is compliant with EN 186270 and IEC 61754-15 standards.

- E2000 cables are duplex types, with 9/125 single mode.

- E2000 cables are PC, UPC and APC types.

- E2000 Fiber Optic Attenuator fit the E2000 type connections.

- E2000 is rather expensive than most of the other types fiber attenuators.

- We supply single mode E2000/APC, E2000/UPC fiber optic attenuators including the bulkhead (Flange type) E2000 attenuator. Attenuation range available is from 1dB to 30dB. These E2000 fiber optic cables feature good quality, competitive prices and fast delivery.



- 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.


- High precision.

- Good stability.

- Easy to operate.

- Small size and bulk.

- Metal ion doped fiber.

- Wavelength independence.

- Data Center Infrastructure.

- High-power light source durability.

- Storage Area Network and Fiber Channel.

- Attenuation levels ranging from 1dB to 25dB.

- Based on IEC/Telcordia Bell GR-326-Core Tested.

- 1310nm, 1550nm, 1250-1625nm and 1350/1550nm dual wave lengths
- Attenuation levels ranging from 1dB to 30dB, with standard and premium tolerances, plus custom configurations.


- Fiber optic test.

- Fiber optic CATV.

- Dense Wave Division Multiplexers (DWDM).

- Erbium Doped Fiber Amplifiers (EDFA).

- Fiber optic communication systems.

- Overpowered fiber optic systems.
