3 PRIVATE AND CONFIDENTIAL © 2016 CommScope, Inc Basic principles of the powered fibre cable system –To provide power and data at a remote location to provide a ‘plug and play’ environment for end user equipment –The cable has a simple construction for cost and weight gains –Modularity and simplicity are key drivers –No need for the complexity of custom cable loss calculations Basic principles of the PoE Extender –Automatically provide the right power for the end user equipment –Automatically provide the right data for the end user equipment –Power and data are combined to be a standard PoE or PoE+ signal PoE = Power over Ethernet –Ethernet uses 8 wires in four pairs –PoE allows 4 wires (2 pairs) to carry power as well as data –All PoE equipment can use this power –PoE can provide 13W, PoE+ can provide 25.5W –Range is limited to approximately 100m –Widely used and mature technology –Powered fibre cable and the PoE Extender can increase this 100m range up to 3000m for PoE and 1600m for PoE+ Introduction Powered Fibre Cable

5 PRIVATE AND CONFIDENTIAL © 2016 CommScope, Inc Types of Installation –Retrofits – Stadium applications including video surveillance and WiFi provisioning –Retrofits – Hospital applications also with video surveillance and WiFi provisioning –Greenfield sites – significant reductions in Power infrastructure cabling –Awkward locations Devices to be powered and power consumption –CCTV cameras, conventional or HD –IP Telephony –Wireless access points –Small Cell –Optical Network Terminals (ONTs) –Digital Signage etc. Distance and power consumption –Farthest distance may not be the system limitation –Calculate the allowable distances for the highest power consumption devices –Distances beyond 3km are not guaranteed, however, if the device is only taking e.g. 7W then a longer run may be possible –For low power devices, powering a PoE powered switch with the PoE Extender may enable multiple devices to be powered System Considerations

6 PRIVATE AND CONFIDENTIAL © 2016 CommScope, Inc Practical Installation Consideration –Any installation, Pole mount, Wall mount or bracket mount involves working at a height –Fibre splicing can be difficult on a platform/scaffolding or bucket lift Intermediate splicing option –Terminate the PoE Extender with a suitable long tail of Powered Fibre Cable –Use a termination block at the end of the source cable –Splice the tail of the PoE Extender to the termination block –Various devices available – TE ‘Gator’ device shown Example Installation Sequence –WiFi AP bracket is installed on a pole –PoE Extender with termination tail fiitted to bracket –Intermediate termination in hand hole/pit/access panel Backbone Fibre cabling option –To power two PoE devices –One ‘backbone’ Powered Fibre Cable to a junction point –Split out to two Powered Fibre Cables to two PoE Extenders Note: this requires an optical 1:2 splitter –Saves cost for long backbone cable lengths System Considerations

8 PRIVATE AND CONFIDENTIAL © 2016 CommScope, Inc PoE Distance and Voltage Calculator is here: NOTE: This is the distance between the power source and the PoE Extender A further 90m can be added to this distance for the cable from the PoE Extender to the powered device Powered Fibre Cable Calculator

9 PRIVATE AND CONFIDENTIAL © 2016 CommScope, Inc Example Installation - GOLD Innovators Award Winner at BICSI Conventional AC power and Fibre Distribution would have been 17% more expensive than the Powered Fibre Cable System Powered Fibre Cable Calculator PoE+ up to 1.6km

10 PRIVATE AND CONFIDENTIAL © 2016 CommScope, Inc Powered Fibre Distribution Box –Currently available version is 12 port –Six Duplex LC optical input cables –Feed through Power connections –Low density (3U height) –32 ports requires 9U but includes optical distribution –2U PSU also required Under Development –32 port 4U height plus 1U for fibre distribution –2U PSU also required –Powered Fibre Cable routed through the front –Split off inside the unit –Power cables go directly out to the PSU –Optical cables go to separate fibre handling Powered Fibre Distribution Box

11 PRIVATE AND CONFIDENTIAL © 2016 CommScope, Inc Single Port Wall/Pole Mount –Input – IP67 Cable gland with three hole insert to accommodate the Powered Fibre Cable –Output – IP67 Cable gland with single hole insert for RJ45 cable –Main box is die cast with 6 captive bolts –IP67 box sealing achieved with custom molded (not glued) ‘O’ ring –Dual purpose lid with wall mount holes and shaped back for vertical pole mount –Recommended orientation is with the RJ45 cable up WAP Bracket Mount (Aruba) –Details as above for the inputs and main box –Lid with mounting points for the bracket –Lid and base have a tie point to ensure the lid is not dropped from a height Regulatory Approvals –Regulatory approvals have been achieved for CE marking, FCC Approval, CSA Approval and RCM Marking –These include Safety: IEC –EMC: FCC Rules CFR 47:2013 Part and Class B –EMC: EN55032:2012 and EN55024:2010 –Surge Protection: K.21 Enhanced and Ingress Protection: IP67 Current PoE Extender

12 PRIVATE AND CONFIDENTIAL © 2016 CommScope, Inc Electrical Details –The two copper conductors can be inserted in either polarity –This input cable can be long (3km) so requires full electrical protection –The input is tested to K.21 enhanced surge protection, this prevents surges being passed through to the powered device –At the end of a long cable, the voltage input can be very low, 28V or less. The PoE extender boosts this back up to PoE levels –The PCB is covered for safety and this doubles up as the fibre tray Fibre Input and Handling –Accepts any 1Gbit SFP compliant with the Multi Source Agreement –Fibre guides and a splice holder are present on the tray allowing two fibres to be spliced Thermal considerations –The base contains heatsinking points which transfer power to the case. –Thermal management is designed to prevent issues at high temperatures, full loads (PoE+ with 90m cable) and long Powered Fibre Cable runs (1.6km) –Care should be taken in selecting the SFP – some GPON SFPs consume up to 3W and are not supported Current PoE Extender

13 PRIVATE AND CONFIDENTIAL © 2016 CommScope, Inc Two Port PoE+ version –Power design content is similar – SELV, NEC Class II 100W input power limit but now providing 60W –Reach will be shorter but the power supply design will be more efficient to partly compensate –Design is at an early stage and the first prototypes for demonstration are not expected until Q –Optical input will be 1Gbit and both outputs will be 1GbE capable –Consideration being given to a two SFP version Two fibres in Separately routed to individual PoE+ ports Possible issue with link loss forwarding Handling devices with one PoE port and one Power port –Examples would be PoE+ cameras with heaters –External splitter proposed to separate out the Ethernet and Power –Multiple versions to accommodate different voltages required –Intelligence to recognise when the external splitter is connected and allow additional power – this would only be available if the other port was not providing full PoE+ power, the total power available is still only 60W or reach is compromised further Case design –A more generic, rectangular style case is being designed with all ports on one side –Thermal management is still important but as the case has to be larger to accommodate the extra port(s) and the power supply is more efficient the same temperature specification will be achieved –Fibre handling will be improved by incorporating an existing conventional fibre handling tray Roadmap

14 PRIVATE AND CONFIDENTIAL © 2016 CommScope, Inc Roadmap Four Port PoE+ version –Can still be SELV but it cannot be NEC Class II as it is now providing 120W –Reach is determined by the input power available and the power loss in the cable, target is to achieve a minimum of 500m –Design is only at concept stage and will lag 2 port development with some paralleling up as resource allows –Demonstrator prototypes not expected until at least Q –Part of the development delay is establishing whether a 10GBit SFP and 10GbE to 4 x 2.5GbE design is feasible in this time –Currently not considering 4 x SFP in to individual PoE+ ports out PoE++ capability –This is currently being researched but has implementation issues as all 8 Ethernet wires (all four pairs) now carry power –It would probably require a dedicated PoE++ version, perhaps the 120W power supply in the two port unit –An extension of the external splitter may be possible to provide higher power DC, e.g. one PoE+ port and one 90W power port for high power devices
