32. Blolite+ - Deep Fibre Deployment Model Blolite+ offers the ability to adopt the deferred cost benefit in deep fibre applications, by installing duct only on day one. The opportunity is equally valid for non air blown fibre access delivery networks, providing the ability to deliver fibre to distribution points.
33. Blolite+ - Access Deployment Model The access network is where Blolite+ delivers the clearest savings, demonstrated later in this presentation. The opportunity exists for either single MultiDuct products laid to the distribution point or a diminishing count multiwayMultiDuct product. Both systems deliver quantifiable savings on both day one costs and ultimate cost irrelevant of market penetration, although the greatest saving are made on lower penetration levels.
34. Benefits of Blolite+ Deferred Infrastructure Material Cost When considering total unique infrastructure material costs, the use of Blolite+ can return up to 75% reduction on day one investment. The saving is achieved through the installation of only a duct infrastructure on day one and then the subsequent supply of fibre as network connections dictate.
36. Benefits of Blolite+ Reduced Cost Per Home Connected When considering the unique infrastructure material cost per home connected, the use of Blolite+ can return savings of up to 49% once 35% connection of home passed is achieved and 27% once 65% connection penetration is achieved. Even when 100% connection to an installed Blolite+ infrastructure is achieved the material costs are 0.5% lower than traditional methods.
38. Benefits of Blolite+ Increased Ability to Connect The Blolite+ system offer the opportunity to connect subscribers where it would not other wise be environmentally or economically viable. Through the use of no dig solutions to bypass physical or environmental obstacles.

Hello and welcome to the last session today of helping you to build better networks.My name is ….. And I am going to talk to you about the way forward with optical fibre.
There are several different types of multimode fibre and the next slide shows predicted volumes
The data from KMI was presented in 2006 regarding global multimode fibre and shows OM1 cablesin decline, OM2 cables in steady growth and OM3 cables in accelerating growth.Brand-Rex actual data (which has a more European bias) shows a very similar trend except for one difference.OM1 cablesin decline, yesOM3 cables in accelerating growth yesOM2 cables in steady growth -no - in fact in declineZ50 (OM4 cables ) this is shown in the red line – we will see more on this later
How did we get here (147m of fibre per person per planet)Standards, standards, standards
At Brand-Rex we believe passionately in the value of standards to provide a relaible baseline for the industry. So much that we participate in 12 fibre optic standards groups.5 in the uK,3 in Europe4 globalRos Neat is the chair of the British Standard group fir optical fibre and cable and the convenor of the international group for optical cables.
First we will start with optical fibre – the heart/centre/core of the cableAnd to start with a few slides on standards for optical fibre
Of the 35 IEC specifications in fact only 4 are commonly used with 3 more being introduced.The next few slides will explore 50-B1.3/G.652D, 50-B6a/G.657 and 10-A1a.3 to be used in OM4 cables.
50-B1.3/G.652DThe main difference is the purity of the glass. Our optical fibre manufacturer has improved the process to reduce the number of OH ions (from water H2O) chemically bonded to the silica. This results in a lower attenuation absorption peak in the 1380nm region of wavelength, hence the fibre is also know as low water peak fibre.Why is this fibre useful?1 for systems using coarse wavelength division multiplexing (CWDM) where the wavelengths are spaced between 1260 and 1625 nm, the extra space allows lower cost lasers to be used2 for operation in the 1310 window – note the water peak is narrower as when it is lower and will provide lower attenuation for future DWDM for 40G or 100G singlemode links It is worth pointing out now the 1550 to 1625 nm region which is where the optical fibre is more bend sensitive hence some of the newest G.657 standards.
This is the newest optical fibre from ITU-T the title is very carefully writtenCharacteristics of a bending loss insensitive single mode optical fibre and cable for the access network The next few slides show the improvements in bending loss
This type of fibre (G657B) has 10x lower bending loss than G657A.This type of optical fibre could lower the risk of high power damage in optical fibres.The following slides give a more detailed look at G657B fibre.
So…. bending loss insensitive single mode fibre It is about the light being more tightly guided to the coreG657A is beneficial for confined spacesG657B is also beneficial for reducing the risk of high power laser damageBoth improve bend loss in the 1550 window – if you are operating at 1310 nm - there is very little benefit – the fibre is not very bend sensitive in the 1310 window.There is a risk of reduced life time if the fibre is used at the minimum bend diameters due to increased surface tension on the glass.
A summary of what I have presented to youOptical fibres G652D, G657 A and B, 60793-10-A1a.3 (for OM4 cabled optical fibres)Cable designs uni and BMCCable protection methods WNM, FS, LU and SWA - this last one is for Steel wire armour which we are adding to our rangeAnd finally labelling to suit your needs

Last of the optical fibres to discussOM4 is nearly hereThe specification IEC 60793-10-A1a.3 has to be finalised by IEC SC86A WG1 and the national committees which ie expected in Q1/Q2 2010.The area causing difficulty is the over filled launch – the current test method is being reviewed and may result in a new method based on prediction from DMD( differential mode delay ( used for the effective laser launch bandwidth.
Now for a change to optical cabling
This is very popular in Europe for FTTH and campus installationsAn initial benefit is the ability to reserve duct space for future growth
This is very popular in Europe for FTTH and campus installationsAn initial benefit is the ability to reserve duct space for future growth
In support of this Brand-Rex has extended its range of microblo cables Features anDBeneFItsMicroBlo (NEW)An extended range of microcables from 2 to 96 fibres and protected microducts and from single way to 24 way, in constructions for direct burial, direct install and indoor environments for Microcable requirements. This allows the network designer to have greater flexibility in planning for short distance urban or long distance remote rural locations. The cable can now be taken from outside routes into a termination point inside the building. Defer & Distribute costs Blolite+ provides a fibre-ready infrastructure that will lower the initial outlay for an installation. The fibre is purchased and installed only when required which reduces the initial capital expenditure by reducing the necessity to install dark fibre. Future proofing / ease of upgrade The Blolite+ infrastructure can be easily expanded and upgraded with minimum disruption to the current network. Different types of fibre can be added as required, allowing end-users to keep up to date with their latest network requirements. Flexibility The MicroDuct infrastructure can be amended, re-routed and new destinations added with minimal disruption and without fusion splicing optical fibre, which optimises the power budget. security Blolite+ brings added security to a network by providing the ability to diversify routings to desired locations. Blolite+ MicroDucts can also provide different pathways for different levels of security. ease of repair The Blolite+ connectivity and accessory range helps to provide a simple repair solution that can be cost effective and quick when compared to traditional methods.
An important note about planningBrand-Rex have an underground cable blowing site and have conducted a series of tests with several manufacturers’ cables and microducts. It showed that installation distance can be increased with fewer bends and straighter routes. A typical route (urban) is likely to have several bends so it is important to plan access points in the route where the cable can be coiled on the surface and then installed into the next section of the route.Similarly for rural areas where direct bury may be required the straightness of the route will have an impact on installation performance.
Another benefit it to reduce the number of splices in a network for FTTH, or any FTTx
A standard cable route can be made up of different fibre count cables towards the end user this is achieved by dark fibre or more commonly splicing In a microduct route this is simply achieved by used of microduct connectors and installing the cable in one length with out splicing.Benefits power budget, time, reliabilty
Some FTTH components in the pipeline1 enclosures for managing microduct eg in and MDU enviromnets2 fibre wall boxes for terminating firbe3 for the office environment we are developing a new face plate for LC, SC and MTRJ
FTTH is not all about Microblo or blown cbalesHere is a recent installetion of FTTH in Sweden (100Mbps to the home)Using a new brand-rex cable - miniature unitubePulled a short distance through external ducts, then through the wall cavity and then termainated into a media converter box with a RJ45 outlet. The end user has to provide the power.It is 3.4 mm diameter universal cable with 4 fibres.
