Bend loss challenge increasing in the future Next-gen systems increase bend loss 2X-4X current systems Standard Current Generation PON IEEE GE-PON downstream (1000BASE-PX-D) ITU-T G-PON Downstream 1490 nm Next Generation PON on Same ODN 10G E-PON downstream 1577 nm 10G-PON downstream WDM PON 1625 nm Bending Loss Increase 3X 4X SCTE /ITU RF-Video downstream 1550 nm RFoG upstream 1610 nm 2X 7

ITU-T G.657 Bend Loss Insensitive SM Fiber ITU-T G.657 Minimum design radius 10 mm Bend Challenged OSP Cable 7.5 mm Most Connectivity Applications G.652D Compliant Long reach and most short reach needs G.657A1 G.657A2 G.652D Compatible Short reach (<1 KM) with sharp bending (MDUs, In residence) NOT A STANDARD G.657B2 (Obsolete) 5.0 mm In Home/MDU Drop NOT A STANDARD G.657B3 8

G.657A1 and G.657A2 fibers Core network applications G.657 A1 fibers OSP Cables with splices and tight bends Drop cables and microcables Your Optical Fiber Solutions Partner G.657 A2 fibers FDHs Central Office Jumpers OFS Proprietary 9

FTTx Drop Applications in the home The drop is the most challenging portion of the network Often requires bending, stapling Rugged cables and ultra bend-insensitive fiber needed Storage 10

Ultra Bend Insensitive fiber cable (G. 657B.3 standard) Designed for the drop, not the backbone Verizon TPR 9424 MDU simulation used to evaluate product performance Staples Bends Weight 11

G.657.B3 Cables Effect of stapling and routing around sharp corners 90-degree bend, stapled ¾ from corner: 5 lb tension, 5.5mm fiber bend radius Aggressive stapling: 19mm bend radius for fiber (minimal bending) Corners are more challenging than staples!

What makes Bend Insensitive Fiber special? Standard Single-mode fiber Allows light to leak out during bending Bend insensitive fiber More complex profile captures light Representative index of refraction profiles (not exact) 13

Compatible with the existing network Typical splice loss Fiber type G.652D G.657A1 G.657A2 G.657B3 G.657A1 0.03 db 0.02 db 0.02 db 0.05 db G.657A2 0.03 db 0.02 db 0.02 db 0.05 db G.657B3 0.09 db 0.05 db 0.05 db 0.02 db 14 14

Splicing bend insensitive fibers OTDR Limitations OTDRs measure backscattered light, which causes limitations with their effectiveness OTDR incorrectly perceives power gain ( gainer or positive event ) AllWave (G.652D) More light backreflected at the interface AllWave FLEX (G.652D and G.657A1) 15

Splicing bend insensitive fibers OTDR incorrectly perceives elevated splice loss Less light back-reflected at the interface, light travels through into larger MFD AllWave FLEX (G.652D and G.657A1) AllWave (G.652D) 16

Splicing bend insensitive fibers Direction 1 Actual loss = (Loss + gain)/2 = Bi directional avg Direction 2 Gainer Actual loss Elevated loss Incoming pulse Outgoing pulse No change in signal shape or system performance due to slightly different MFDs AllWave (G.652D) AllWave FLEX (G.652D and G.657A1) 17

Bend insensitive math For drops, bend loss is more important than splice loss In-Residence Drop Cable Loss vs. Fiber type Attenuation Loss Component, 1550 nm (db) G.652D G.657A2 EZ-Bend fiber Inherent fiber loss (100m) 0.03 0.03 0.03 Attenuation due to bending in the Verizon MDU Drop Cable Simulation (TPR-9424) Dark (>30 db) 2 to 5 (midpoint, 3.5) <0.2 Splice loss (1 splice to G.652 fiber) 0.02 0.04 0.09 SC-APC to SC-APC Connector Loss (0.15/ connection, 2/link) Attenuation total or typical link status 0.30 0.30 0.30 Over 30 (Link will not work) 3.87 (Likely to create link failure) 0.62 (Well within acceptable limits) 18

MDU Headend/Closet Options 21

MDU Headend Options Low fiber count options Many MDUs lend themselves to splitter placement on-site Tight spaces often dictate use of wall-mounted materials Rack mounted sometimes an option Double capacity with LC connectors Very cost effective hardware available on the market

MDU Headend Options Higher fiber count options Larger MDUs require more capacity Patch, splice, and combination wall and rack mounted options available Single fiber and ribbon options available

MPO Module Based Splitters Ribbon solutions are excellent for space challenged areas Elegant fiber management 8 fiber MPO fanouts to LC or SC connectors Minimizes mess, less chance of jumper damage Easy installation procedure Cost competitive with single-fiber solutions Your Optical Fiber Solutions Partner OFS Proprietary

In-unit solutions 36

In-unit deployments MDU homeowners are sensitive to cable deployments within homes The customer dictates terms inside unmanaged bends Relatively common for customers to refuse service due to aesthetics Anecdotal number is 5%-10% You want to put that in my crib?? No way! 37

In-unit pathways are challenging Your Optical Fiber Solutions Partner OFS Proprietary 38
