Introduction Unprecedented growth in the telecommunications industry has driven wide-spread deployment of optical fiber over the past few years. As a result, many service providers are finding that their existing fiber frames and troughs are overflowing with large masses of optical fiber patch cords. In addition, the rapid deployment of SONET/SDH, fiber in the loop and video initiatives has created the demand for increased termination density at the fiber distributing frame. Service providers must build a sound network infrastructure that will provide a solid base for delivering the new and enhanced broadband services promised by the ever-advancing information superhighway. What's Next? It's clear that simply adding additional fiber frames to an existing FDF lineup is not the answer, as conventional fiber frames allow only a small number of bays in a lineup before the horizontal trough system becomes unmanageable. A more innovative fiber management plan is needed that will provide unlimited expansion as well as alleviate jumper pile-up in the horizontal troughs. With the introduction of its Next Generation Frame family of products, ADC offers the innovative solution that service providers have been waiting for. Designed specifically to provide higher density while improving fiber cable management, the Next Generation Frame product family allows for virtually unlimited growth. Frames ADC's Next Generation Frame product line has fiber frames designed to fit a variety of termination, splice, and storage applications. Each frame option is designed with an emphasis on superior cable management and ease of use, including features such as ample trough space for cable and jumpers, easy access to connectors, and storage for jumpers. The frame sections are shipped from the factory fully equipped with all cable management hardware including a built-in jumper storage panel. Fiber Termination Blocks (FTB) Fiber Termination Blocks (FTBs) are available with SC, FC, ST and E-000 adapters in block configurations of 8, 7 or 96 positions. Also, 1 position FTBs are available using LX.5 and LC adapters. FTBs utilize sliding adapter packs to gain easy access to both the front and rear connectors. There is also a block configuration available to accommodate Mini Value-Added Modules (Mini VAMs) for applications requiring splitters or WDMs. FTBs can be ordered with or without IFC or outside plant cable. Fiber Combination Blocks Blocks (FCB) Fiber Combination Blocks (FCBs) provide termination and on-frame splicing capabilities, all in one block. The block occupies two mounting positions on the frame section. They are available with SC, FC, ST and E-000 adapters in block configurations of 8, 7 or 96 positions. Also, 1 position FCBs are available using LX.5 or LC adapters. Features and Benefits Ample Trough Space Reduces jumper pile-up and congestion - Reduces maintenance time due to easy removal and tracing of jumpers - Minimizes risk of microbends or damage to fiber Built-in Jumper Storage Panel Minimizes number of required jumper lengths Maintains fiber bend radius Simplifies frame installation - Saves money by reducing the number of different jumper lengths that have to be kept in inventory - Minimizes risk of microbends or damage to fiber Sliding Adapter Packs Promotes high density Provides easy access to connectors - Saves valuable floor space - Reduces time required for operations and maintenance Intelligent Cable Routing System No fiber cross-over points Multiple vertical troughways - Reduces maintenance time due to easier removal and tracing of jumpers and minimizes fiber weaving 1

Fiber Main Distributing Frame (FMDF) The FMDF is the cornerstone of the NGF product line. This innovative frame has six rear horizontal troughs. This abundant trough space minimizes fiber pile up and congestion leading to easier jumper traceability and removal. The frame has twelve Fiber Termination Block (FTB) mounting positions equally divided between vertical columns on the left and right sides of the frame as shown in the figure below. The frame is 600 mm wide x 600 mm deep. The built-in jumper storage panel will store up to 5 meters of jumper slack.

Front Facing Fiber Main Distributing Frame (F3MDF) 3/03 85 Next Generation Frame 600 mm Products The F3MDF is designed for single-sided access applications and may be mounted up against a wall or back-to-back to save floor space. Unlike the FMDF, the more compact F3MDF is equipped with a single 30 mm horizontal trough. The F3MDF has twelve FTB mounting positions equally divided between vertical columns on the left and right sides of the frame as shown in the figure below. The frame is 600 mm wide x 80 mm deep. The built-in jumper storage panel will store up to 5 meters of jumper slack.

Fiber Slim Rack 3/03 85 Next Generation Frame 600 mm Products The Fiber Slim Rack is designed for lower density applications than the FMDF or F3MDF. It has six FTB mounting positions and is designed for single-sided access applications. The Slim Rack is intended for use in a single frame application and should not be used in a multiframe lineup. The built-in jumper storage panel will store up to 5 meters of jumper slack. When ordering FTBs for the Slim Rack, remember that only left oriented blocks are used on this frame.

Fiber Termination Blocks (FTB) Unterminated FTBs without fiber can be ordered fully loaded with adapters or empty (no adapters), in which case the adapter packs for the block must be ordered separately (see page 1). Before ordering, determine the block orientation and cable exit direction. Unterminated FTBs may be ordered with a left orientation (mounts on the left side of the frame) or a right orientation (mounts on the right side of the frame). The cable exit direction will be either upward (cables terminated to the rear side of the block exit up toward the top of the frame) or downward (cables terminated to the rear side of the block exit down toward the bottom of the frame). All blocks with adapters only are configured to terminate single or dual jumpers on the rear of the block. If a multi-fiber breakout style cable (i.e., OSP/IFC) is to be terminated to the rear of the block, a separate clamping kit is required (see page 6).

Fiber Termination Blocks (FTB) Preterminated Preterminated FTBs are available with either indoor or outdoor rated cable in ribbon or stranded configurations. All blocks are 100% factory tested to guarantee continuity and reliable connections. Preterminated FTBs make installation quick and easy, reducing labor costs. Before ordering, determine the block orientation and cable exit direction. Preterminated FTBs may be ordered with a left orientation (mounts on the left side of the frame) or a right orientation (mounts on the right side of the frame). The cable exit direction will be either upward (cables terminated to the rear side of the block exit up toward the top of the frame) or downward (cables terminated to the rear side of the block exit down toward the bottom of the frame). Preterminated Fiber Termination Blocks arrive from the factory with either IFC or OSP Cables Fiber cable easily uncoils during installation Ordering information follows on next page.

Fiber Combination Blocks (FCB) Fiber Combination Blocks provide a place to terminate pigtails and splice IFC/OSP cables on the frame. The blocks are available with several different adapter types in block configurations of 8, 7, or 96 positions. Also, a 1 position FCB is available using an LX.5 adapter. The termination portion of the fiber combination block utilizes sliding adapter packs to gain easy access to connectors on both the front and rear side of the block. The block is available with factory-installed pigtails for easy installation. Splice trays are shipped with the block if ordered with pigtails; otherwise trays must be ordered separately. The block is shipped with a cable clamp for OSP/IFC. The FCB occupies two mounting positions on a frame section. Before ordering, determine the block orientation. FCBs may be ordered with a left orientation (mounts on the left side of the frame) or a right orientation (mounts on the right side of the frame). Ordering information follows on next page. 9
