MPO ASSEMBLY Description The MPO optical fiber system is made up of pre-terminated multi-core optical fibre cables (trunks) that plug into pre-terminated optical fiber cassettes. The MPO optical fibre cable consists of 12 core, pair-wise flipped, optical fiber cable trunk terminated in 12-way, MPO connectors that plug into a straight optical fiber cassette, at each end. The MPO system is available in multimode and singlemode versions. The trunks are available in customized lengths. The AMP NETCONNECT MPO system is designed to provide very low loss and requires an odd number of cross-overs in the channel to comply with TIA-568-B1-7 Connectivity method C. The MPO system components are manufactured and tested at the Tyco Electronics AMP NETCONNECT optical fiber assembly manufacturing plant. When the system is installed on site, it is required to be field tested in accordance with ISO/IEC 14763-3 (1 Jumper or Three test cord method) using a light source- power meter test set.

Male and Female connectivity MT-technology always needs male and female connectivity. The guide pins act here as a kind of sleeve function, as in single ferrule technology.

MPO products from Tyco Electronics have the following configuration as standard: Product Male/Female Cassettes Male Trunk cables Female MPO patch cord Female MPO Transceiver Male MPO Fanout Female Note: All cassettes have a male MPO connector; hence any trunk cable must have a female connector

MPO cable straight configuration and without pins

Note: In principle all these products can be built in the opposite way, ie cassettes have no pins but the cables have pins etc. Fan out assemblies The configuration for fan out cords can be different from that which applies in particular for direct connections. Application: Fan out assemblies are most likely to be used as a direct connection to a switch. The application is the same as for MRJ21 to RJ45 connectors. In the case of MPO one assembly is with, the other one without pins.

MPO Polarity Configurations

In each fiber optic system, the link from Transmitter (Tx) to receiver (Rx) needs to be flipped once. In a complete MPO link this flipping is provided by one flipped cassette, whilst all other components in this link shall be installed as straight version. The picture above is the standard configuration and ensures at any time that the link is working. The picture below shows a 4 cassette example.

Note: The Tyco Electronics solution is a straight trunk cable and one flipped cassette in the channel.

Patch cords from Tyco Electronics follow this configuration even though they offer a removable clip. This clip shall be used only in case of installed channels which are not standard compliant.

AMP Hi-D AMP Hi-D is a cabling platform for your IT infrastructure. The platform embraces different kinds of products and features designed for future IT infrastructures requiring high density solutions. In line with the desire of organizations to provide more performance in less space within their Data Center environment while meeting power consumption objectives, AMP NETCONNECT has realized the need to develop focused product sets for these environments that meet the design objectives of ensured high density performance, seamless migration and user flexibility at a reduced power level.

AMP Hi-D is an excellent cabling platform for fiber installations. With our cable managers and fiber drums we can offer a robust solution in order to address the following subjects:

Installation Procedure The MPO trunk shall be laid in pathways (not pulled), unless it is being installed in conduits. Ideally, the best pathway is a duct (metallic or non-metallic) that fully protects the MPO trunks from other cable types.

Where a cable must be pulled any tension shall only be applied to the installed pulling sock with a maximum of 350 Newtons.

19

The minimum bending radius specified for the trunk type shall be observed at all times. The trunk shall be fixed to the panel. The pathway fill specified in the pathways and spaces standard (30% to 50%) shall be observed. The trunks shall be connected to the cassette by simply plugging the MPO connector into the appropriate MPO coupler as identified in the design plan. Prior to plugging into the coupler, both MPO plug and coupler shall be cleaned using the method described in the cleaning section. All trunks and cassettes shall be labelled in accordance with the administration standard and the specified requirements. The equipment cords shall be the duplex type and installed to complete the communication channel. Appropriate patch cord management shall be provided to ensure minimum bending radius, crush resistance and fill ratios are observed.

Cleaning MPO Connectors, Cassettes and Trunks

1918809-1 MPO IBC Cassette Cleaner: Suitable for MPO Cassettes, MPO coupler and MPO plugs

1918808-1 1.25 mm stick cleaners: Suitable for LC couplers 1918807-1 2.5 mm stick cleaners: Suitable for SC couplers 0-2064499-1 Suitable for SC connectors 0-2064500-1 Suitable for LC connectors Note: Cleaning is an essential part of MPO and any high speed fiber system. Reason is the low budget of such systems. If the budget for 10 Gigabit Ethernet is 2.55 dB, it is going to be about 1.7 dB for 40 Gb/s.

21

Cleaning Procedure MPO Connectors, Cassettes and Trunks

LC, SC couplers 1. Insert the tip of the cleaning stick into the adaptor

opening 2. Rotate the cleaning stick clockwise while applying

varying pressure to create a gentle back and forth pumping action where the tip of the cleaning stick contacts the ferrule.

3. Inspect with microscope for cleanliness and repeat steps 1and

4. 2 if needed until any contamination is removed. 5. Discard the stick after use.

MPO Cassette/Coupler 1. Insert the cleaning tool tip into the MPO adapter as shown. 2. Rotate the wheel in the direction indicated on the cleaning

tool. 3. Remove the cleaning tool from the MPO adapter. 4. Inspect with microscope for cleanliness and repeat steps 3,

4 and 5 if needed until any contamination is removed.

MPO Plug (Trunk connectors) 1. With the clear cover installed it is also possible to clean

the MPO connector plugs 2. Lift the clear front cover, Insert the MPO plug as

shown. 3. Rotate the wheel in the direction indicated on the

cleaning tool 2 or 3 times. 4. Inspect with microscope for cleanliness and repeat

steps if needed until any contamination is removed.

LC/SC coupler IBC cleaner 1. Insert the tip of the IBC tool into

the adaptor opening 2. Push carefully until you hear an audible click 3. Take out the tool and Inspect with microscope for

cleanliness and repeat steps 1 and 2 if needed until any contamination is removed.

22

The importance of a clean endface is shown in the pictures below. Two connectors have been mated one, two and five times. Each time more dust is collected and even more important the dust particles are moving towards the core (see pictures and table). This has a deep impact for 1 and 10 Gb/s channel testing. As ISO/IEC 11801 has defined a channel budget of 2.55 dB for OM 300 channels any contamination of the endface is critical.

Data Centers The MPO solution is ideal for data center applications. The latest data center structured cabling standard, TIA 942, defines the cabling layout and cabling performance requirements. Structured Cabling Concepts in Data Centre

The ISO / IEC data center communication cabling standard defines the topology and performance specifications of the cabling media that could be used in such an environment. The minimum optical fibre cable defined in this standard is OM3. The MPO solution is ideally suited to fulfill the performance requirements defined in this standard.

25

A typical data center layout is shown above. The communication network enables the various network devices to perform their activity in the most efficient manner. The MPO trunks are reticulated in modular, (yellow) light weight, Low Smoke Zero Halogen polymeric ducting, designed and manufactured specifically to protect the optical fiber trunks from abrasion and sharp edges and to provide segregation of the optical fibre installation from the copper cabling system. Optical fiber systems like the The AMP NETCONNECT PLUG&GO MPO system require much smaller pathways than copper cabling systems. This reduces space in congested ceilings, while segregating the optical fibre cabling from other services. This pathway system provides the appropriate minimum bending radii required by the optical fiber trunks to prevent performance deterioration and simplifies installation by allowing the optical fiber trunks to be laid into the ducts, rather than pulled.
