Corning Incorporated is a diversified technology company with a proud history of developing breakthrough innovations that significantly improve people’s lives. We have been changing the world through innovations for more than 150 years, integrating scientific discovery with market need. We focus on high-impact growth opportunities in the telecommunications, flat panel display, environmental, life sciences and semiconductor industries.

As early as 1974, when fiber optic technology was still in its initial stage, Corning was one of the original pioneers, with expertise second to none. We were working with Europe’s leading Public

Telecommunications companies in developing trial

fiber optic cable routes. In 1977 came the first fiber optic route for Deutsche Telekom in Berlin. This was followed in 1979 by further projects in the USA, marking the start of a global business with a string of major commercial contracts.

In 2000 Corning grouped all its cable, hardware and

equipment businesses into Corning Cable Systems

division. Corning Cable Systems now comprises

the former Siecor Corporation, the communication

cables business from BICC (Corning Cables Ltd.),

Siemens´ former Communication Cables division

and RXS Kabelgarnituren.

In the area of copper cabling, the mature Series

71 came out in 1971 as an MDF product with IDC technology, followed by a set of most successful products like in Series 5000 and Series 1000RT.

Today Corning Cable Systems disposes of more than 35 years of rich experience in successful copper IDC

technology. Customers around the world appreciate

Corning MDF products for performance highest

quality and reliability.

Distribution System Series 71

Technical Principles

The binary structure of the switching systems (8, 16 or 32 subscribers per line card) is the reason that distribution blocks intended to connect the switching system also have a binary structure, e.g. a 4-pair functional element in the case of the Series 71 or an 8-pair functional element in the Series 5000.

The subscribers are generally connected via cables organized in groups of ten. Accordingly, the distri

-bution blocks have a n x 5 structure for the Series 71 (5-pair functional element) or a n x 10 structure for the Series 5000 (10-pair functional element).

The number of system or subscriber lines to be connected per distribution block depends mainly on the

pair count of the cables used. Most of the subscribers in the central office are therefore connected to the relevant distribution blocks using 100 or 200 pair cables. The same applies to the system side, where 128 wire pair cables are used.

The above described systematics is best supported by the 8- and 10-pair distribution blocks of the

Series 5000 with 100, 128, 200 and 512 wire pairs. Series 71 Distribution Blocks are less space effec

-tive and need twice the number of functional elements to support similar wire pair counts. As described

on page 10, a distribution block basically consists of a metal chassis, functional elements and wire guides. The wire guides ensure that the wires are clearly organized in the distribution block. Each wire pair is led to the relevant IDC contacts through the wire guides.

The importance of having good wire and cable organization increases with the number of users to be

connected. The jumper comb assemblies of the distribution blocks and the jumpering loops of the dis

-tribution frames are therefore just as important to good cable organization as the wire guides.

Insulation Displacement Connection

Soldering methods were replaced by connection techniques via cutting insulation some decades ago. Through this change, time-consuming soldering, screwing or filling procedures have been eliminated. With

this technology, the wire is inserted in the IDC contact (Insulation Dis

-placement Connection) by hand and pressed into it by using a simple termination / punch-down tool. The wire insulation is stripped during the termination process in the IDC contact where the connection is made. DIN IEC 352 describes the requirements for this soldering-, screw- and stripping-free connection in detail.

Double IDC Contact

Functional elements of Series 71 distribution blocks are always fitted with double IDC contacts. The double contact allows interruption-free jumpering. This means that in addition to the existing connection, e.g.

jumpers from the subscriber to the system, a second connection to a

new connecting point can also be established without interrupting the existing connection.

Distribution System Series 71

Technical Principles

Main Distribution Frame

Tasks

The main distribution frame (MDF) is the interface between

the subscriber cables coming in from all directions and the

switching system. The subscriber cables and the system

cables are all led and connected to the main distribution

frame. The connection between both cable sides is imple

-mented by jumpering. In addition to connecting and orga

-nizing all cables, the main distribution frame also provides the option to install protection against overvoltage and over-

current for service technicians and the switching system itself. Subscriber and system cables can be both checked

and disconnected in the main distribution frame; xDSL

splitters for data transmission can be installed as well.

Options for Application

Main distribution frames are used wherever a large numb

-er of subscrib-ers needs to be connected with the switching

system, for example in networks of telecommunications pro

-viders or in large buildings such as banks, insurance

compa-nies and headquarters of global players.

Jumperin

g

All underground subscriber cables are connected to specific distribution components (line or subscri

-ber block) in the main distribution frame. Not every subscri-ber wire pair is necessarily connected to a subscriber. By the same token spare pairs in subscriber cables do not need to be connected to the switching system. Additional subscriber wire pairs are only connected to the system if required.

Frequently the switching system and the main distribution frame may not be in the same room or even on the same floor. Given that each operating wire pair cannot be guided to the switching system over several floors, the required wire pairs are connected to an additional distribution component (system block to which the system cables are connected). Thus the wire pairs in use are connected in stages to these distribution components. These connections are in turn connected to the switching system via cables (e.g. 128 wire pairs). The cables can then be led over several floors to the switching system without any difficulty.

Distribution System Series 71

Technical Principles

Distribution Frame Variations

Main distribution frames can be arranged vertically or vertically / horizontally and are available as wall-mounted or free-standing variants.

The choice of the distribution frames depends on the location as well as on the number of subscribers that have to be connected. Corning Cable Systems recommends that merely vertical distributors should be used for less than 5,000 - 10,000 subscribers to be connected. If the number of subscribers is higher,

the need for cross jumpering increases. We therefore recommend using a vertical / horizontal distributi

-on frame which best supports cross jumpering between the horiz-ontal distributi-on blocks. By comparing

the option for cross jumpering of both MDF types, the difference becomes obvious: in a distribution

frame with 13 horizontals there are 12 cross jumpering options, whereas most of the vertical distribution frames offer cross-jumpering only above and below the vertical distribution blocks.

Technical Principles

Overvoltage

Overvoltage / Overcurrent Protection

Damage caused by overvoltage / overcurrent is one of the most common causes of malfunctions in

communication devices. Overvoltage / overcurrent can stop individual components or even result in the failure of entire central offices. Without sufficient protection, telecommunication equipment is exposed

to a potentially costly and dangerous threat. Damage can be caused by lightning, electrostatic or elec

-tromagnetic interference or by power lines coming into contact with communications lines.

Primary protection against such damage consists in inserting protection magazines into the distribution

components and in grounding the system in accordance with the relevant requirements.

In the context of telecommunications, a distinction is made between the following types of protection:

Overvoltage Protection (3-Point Protection)

The overvoltage protection magazines / plugs are

fitted with 3-electrode arresters (see the circuit dia

-gram on page 27 et sqq.). In case of overvoltage, an arc is generated in the arrester which discharges the energy towards the ground potential. The arc is

broken when the voltage falls below the nominal re

-sponse direct voltage of the arrester. This reversible

procedure can be repeated a number of times if

ne-cessary.

Overcurrent Protection (2-Point Protection

)

The overcurrent single pair protector is fitted with PTCs, i.e. Positive Temperature Coefficient (see the

circuit diagram on page 27 et sqq.). When the nomi

-nal current of the PTC is exceeded, the component

heats up and the resistance increases exponentially. The PTC therefore limits the current. The PTC cools down in accordance with the load and then returns to its original state. This reversible procedure can also be repeated a number of times if necessary.

Protection Magazines Series 71

Communications equipment and systems for data transmission can be damaged or even destroyed by

overvoltages and the resulting current surges or by overcurrent. Protection magazines offer optimum primary protection in such cases. The surge arresters limit overvoltages quickly and safely to uncritical levels and reliably discharge the resulting dangerous currents. Optional PTC in 2-Point Protection Plug

to be installed from the front side limits overcurrent by increasing its resistance and therefore blocking

the current.
