Introduction: The DCI Fiber Challenge
Data Center Interconnect (DCI) architecture connects core, edge, and colocation facilities into a unified network fabric. As workloads surge — from AI, cloud replication, and distributed storage — operators are pushing DCI bandwidth to unprecedented levels.
To meet these demands, data center fiber optic solutions are turning to ultra-high-fiber-count ribbon cables, with up to 6,912 fibers per trunk. Ribbon fiber technology delivers massive density and fast installation via mass-fusion splicing — but only if matched with the right connectivity hardware.
Clearfield’s Clearview® Cassette ecosystem is designed exactly for that challenge.
The Clearfield Advantage: Engineered for DCI Density
Clearfield’s Clearview Blue and Clearview Black cassettes — deployed inside FieldSmart® FxMP, FxHD, and FxDS panels — offer a unified, modular architecture that simplifies every stage of DCI deployment: from ribbon splicing to patch management.
1. Modular Building-Block Design
- Each cassette manages a 12-fiber ribbon, the natural grouping for high-count cables.
- Simplifies inventory and training — one cassette family works across data center and OSP environments.
- Enables a “pay-as-you-grow” expansion model with no wasted rack space or stranded capacity.
2. Ribbon Cable & Mass-Fusion Ready
- Supports 200 µm and 250 µm ribbonized fibers for trunk cables up to 6,912 fibers.
- Integrates splice trays and slack storage within the cassette — no external trays required.
- Enables mass-fusion splicing directly inside each cassette for faster turn-up and cleaner fiber management.
3. FieldSmart® High-Density Platforms
- Compatible with FieldSmart FxMP, FxHD, and FDP panels — delivering up to 576 LC or 288 SC connections in 4RU.
- Offers front and rear access for patching, splicing, and testing.
- Integrated radius fingers and bend-protection rings safeguard fibers from micro-bends and ensure long-term reliability.
4. Craft-Friendly, Low-Maintenance Design
- Tool-less front access for adds, moves, and changes.
- Built-in slack storage maintains bend-radius compliance.
- Pre-terminated and field-terminated options reduce installation time.
- Large front-facing labeling windows simplify port documentation.
DCI Deployment Example: Managing 6,912 Fibers
Step 1 — Trunk Termination
A 6,912-fiber ribbon cable enters the facility through an outside plant (OSP) vault and terminates into Clearview Black cassettes inside a FieldSmart FDP rack. Each 12-fiber ribbon is mass-fusion spliced within the cassette’s built-in tray.
Step 2 — Transition to Inside Plant
From the FDP, pre-terminated MPO trunks route to a FieldSmart FxMP frame populated with Clearview Blue cassettes. Each cassette provides 12 LC duplex ports, neatly organized for front patch access.
Step 3 — Cross-Connect & Expansion
MPO jumpers between Blue and Black cassettes minimize jumper congestion and simplify labeling. Unused rack positions remain available for future cassettes, allowing incremental DCI growth without re-engineering the fiber plant.
Step 4 — Operations & Maintenance
Routine inspections include connector cleaning, slack check, and port verification. With full front access and protected bend control, maintenance can be completed quickly — even with thousands of live fibers in service.
Design Tips for DCI Using Clearfield Ribbon Cassettes
- Design Around Ribbon Groups
Match 12-fiber ribbons to 12-port cassette increments for clean scalability. - Mix Clearview Black and Blue
Use Black for OSP termination and Blue for data hall patching. The consistent internal geometry ensures identical handling. - Use MPO Trunks Between Frames
MPO connections between cassettes reduce cable bulk and streamline high-density cross-connects. - Plan Front & Rear Access
Select FieldSmart frames with front-rear accessibility to simplify splicing, testing, and patching. - Protect Bend Radius
Always route fibers using Clearfield’s built-in radius fingers and slack guides to maintain optical performance. - Document and Label Clearly
Use the large cassette labeling windows for port IDs, fiber groups, and trunk designations.
