DCF (Dispersion-Compensating Fiber) is a specially designed optical fiber used to compensate for chromatic dispersion accumulated in conventional single-mode fiber transmission. With a high negative dispersion coefficient, DCF counteracts positive dispersion over long transmission distances and helps maintain optical signal integrity and system bandwidth. The C-LIGHT DCF product family uses G.655 fiber and provides 20km to 120km dispersion compensation options in a 1U form factor for C-band optical communication systems.
DCF provides negative chromatic dispersion to counteract the positive dispersion accumulated in standard optical fiber, helping reduce pulse broadening during long-distance transmission.
The product family is designed for C-band optical transmission systems and can be integrated into high-capacity WDM and long-haul network architectures.
The listed DCF models use G.655 optical fiber, providing a fiber platform designed for dispersion-managed optical transmission systems.
20km, 40km, 60km, 80km, 100km, and 120km dispersion compensation options are available to match different transmission system requirements.
CL15DCF201U provides 20km dispersion compensation for C-band optical transmission systems in a 1U form factor.
CL15DCF401U and CL15DCF601U provide 40km and 60km dispersion compensation options for systems with different accumulated dispersion requirements.
CL15DCF801U and CL15DCF1001U provide 80km and 100km dispersion compensation for longer transmission spans.
CL15DCF1201U provides the longest listed 120km compensation option for C-band transmission systems requiring higher dispersion compensation capacity.
Conventional single-mode fiber can accumulate chromatic dispersion as optical signals travel over long distances, causing different wavelength components to propagate at different speeds.
DCF introduces negative dispersion that counteracts the accumulated positive dispersion of the transmission fiber.
Balancing the dispersion characteristics helps reduce pulse broadening and supports clearer optical signal transmission over extended distances.
Effective dispersion management helps maintain signal integrity and supports higher-speed optical communication systems over long fiber spans.
DCF addresses chromatic dispersion accumulated in transmission fiber, while EDFA provides optical amplification to compensate for optical power loss.
DCF and EDFA can be deployed together in long-haul optical systems to manage both signal dispersion and optical power across extended transmission spans.
The combination of dispersion compensation and optical amplification can support stable operation of high-speed and high-capacity optical transmission links.
The 1U DCF platform can be integrated with other optical transmission equipment in rack-based WDM and long-haul network environments.
DCF is used to compensate chromatic dispersion in long-distance fiber transmission systems where accumulated dispersion can affect signal quality.
It can be integrated into backbone transmission systems to support dispersion management across extended optical fiber routes.
DCF can provide dispersion compensation in selected metro and regional systems that require controlled chromatic dispersion over longer optical spans.
DCF is suitable for C-band WDM systems where multiple wavelength channels require effective dispersion management during long-distance transmission.
These models are suitable when the transmission system requires moderate dispersion compensation for shorter or intermediate fiber spans.
These higher-distance compensation models are designed for systems with greater accumulated dispersion across longer transmission spans.
DCF stands for Dispersion-Compensating Fiber. It is an optical fiber designed to provide negative dispersion and compensate for chromatic dispersion accumulated in transmission fiber.
The listed DCF models use G.655 optical fiber.
The listed DCF products are designed for C-band optical transmission systems.
The product family provides 20km, 40km, 60km, 80km, 100km, and 120km dispersion compensation options.
Yes. DCF and EDFA provide complementary functions in long-haul optical networks, with DCF managing chromatic dispersion and EDFA compensating optical power loss.
DCF provides negative chromatic dispersion compensation for C-band optical transmission systems, helping reduce pulse broadening and maintain signal integrity over long fiber spans. With G.655 fiber and 20km to 120km compensation options in a 1U platform, it supports flexible deployment in long-haul, backbone, metro, and WDM networks.
