Corning Vascade EX2000 Bare Optical Fiber
Vascade EX2000 is Corning's G.654.D ultra-low-loss large-effective-area submarine fiber for advanced space division multiplexing systems. It combines low attenuation with an effective area in the 100 µm² range, designed for the high fiber-count submarine cables that carry trans-oceanic internet capacity.
- ITU-T standard
- G.654.D
- Effective area (Aeff)
- ~100 µm²
- Attenuation @ 1550 nm
- ≤ 0.165 dB/km
- Coating options
- 242 µm or 200 µm
G.654.D specifies pure silica core fiber with effective area greater than 80 µm². EX2000 sits at the top of that range, with an effective area around 100 µm², reducing nonlinear noise in high-power DWDM submarine repeater chains. Attenuation is typically below 0.165 dB/km at 1550 nm. Available in both 242 µm and 200 µm coating, with 200 µm being standard for high-count submarine cable designs.

Frequently Asked Questions
What is the difference between Vascade EX2000 and EX2500?
EX2500 has a larger effective area (approximately 130-150 µm² vs 100 µm²) and is designed for very long submarine routes where nonlinear noise is the dominant system limitation. EX2000 balances effective area and mode field diameter for practical submarine cable manufacturing. EX2500 is used when maximum reach per repeater span is the priority regardless of cable design complexity.
