Optical Fiber Distribution Frame

The optical fiber distribution frame provides structured cabling termination, cable storage, and fiber splicing inside high-density telecommunication environments. Engineered with a modular structure, this central cross-connect platform accommodates up to 2016 splice and patch ports across an ETSI or standard 19-inch footprint. Integrated routing pathways protect fiber bend radius across all internal routes, ensuring stable transmission performance for data centers, central offices, and regional optical networks.

This optical distribution system functions as a floor-standing framework that organizes, routes, and terminates high-count optical cables. It supports up to 14 modular 3U patch subracks within a 47U frame structure. The design integrates separate management zones for incoming bundle cables, modular routing tubes, and front-facing patch cords.

Key Features

• Port Capacity: Terminates up to 2016 ports for combined splicing and patching functions.

• Bend Radius Protection: Maintains a continuous minimum bend radius of 35 mm throughout the framework and internal cassettes.

• Cable Guidance: Features dedicated cable glands on the base alongside slotted guide compartments to control incoming fiber protection tubes.

• Subrack Integration: Houses up to 14 units of 3U patch panels equipped with side-access trays for installation and maintenance.

• Modular Cassette Support: Operates interchangeable double-sided cassettes built for splice, patch, WDM, and splitter module options.

• Structural Hardware: Incorporates a locking front door assembly with powder-coated surfaces for physical equipment security.

Product Configuration

The frame is configured to support high-density fiber management components:

• Frame Unit: 47U total mounting height compatible with ETSI and standard 19-inch equipment.

• Patch Subracks: Holds up to 14 units of 3U patch panels (144 ports per subrack).

• Cassette Architecture: Double-sided design separating splice trays from storage compartments.

• Module Density: Accommodates up to 24 cores using LC duplex interfaces or 12 cores using SC adapters per unit.

• Protection Tubing: Compatible with polymer miniflex protection tubes routed via designated guide slots.

Applications

• Central office main optical distribution frames (ODF).

• Telecommunication network cross-connect sites.

• Data center fiber meet-me rooms.

• High-density optical line terminal (OLT) consolidation hubs.

• Splicing and patch cord routing for regional FTTx networks.

Deployment and Cable Routing

• Incoming Feed Setup: Bundle cables enter from the ground level and secure via dedicated bottom cable glands.

• Tube Routing: Protection tubes pass through slot-type compartments to reach the individual splice trays without crushing fibers.

• Patch Cord Management: Fiber patch cords route through integrated vertical channels, dedicated mandrels, and curved guide segments into the excess cable storage field.

Selection Considerations

• Adapter Footprint: Determine if the optical line deployment requires SC connections (12 cores per module) or high-density LC duplex connections (24 cores per module).

• Splice vs Patch Balancing: Verify total port demand up to 2016 positions to calculate the required quantity of 3U subracks (144 ports per subrack).

• Optical Component Integration: Confirm requirement for custom internal cassettes holding splitter circuits or WDM filters within standard subrack slots.

Frequently Asked Questions

What is the maximum fiber termination capacity of this frame?

The frame holds up to 2016 splice and patch ports when loaded with 14 units of 144-port 3U subracks.

Which adapter types work with the internal subracks?

The double-sided cassette design accommodates SC simplex adapters (up to 12 cores) and LC duplex adapters (up to 24 cores).

How does the frame prevent fiber micro-bending and signal attenuation?

The design maintains a minimum 35 mm bend radius guide curve along the frame channels, routing mandrels, and cassette housings.

Can passive optical splitters mount inside the subracks?

Yes. The subracks accept modular cassettes designed for optical splitters and WDM devices alongside standard splice and patch modules.
