Dispersion Compensating Fiber DCF from Germany
High negative dispersion optical fiber used in DWDM systems to compensate chromatic dispersion of standard SMF, enabling long-haul voice, data, and video transmission at 10/40/100G rates. Typical -80 to -100 ps/nm/km dispersion at 1550nm. HTS 9001.10.0030 classification.

Import Tips
• Provide dispersion slope and PMD specs for system compatibility
• Declare figure-of-merit (dispersion/slope normalized to loss)
• Confirm splicing compatibility with G.652 SMF (9/125μm)
