Challenges and Considerations
• Future upgrade possibilities
– Every 5 years a new generation of PON technology
• Filed connectorisation vs preterminated in factory
• Mechanical splice vs. fusion splicing
• Home passed vs. connected homes / subscriber
• Scale and speed of deployment
• “Network sharing”
• Different geographies and installation environments
– SFU, MDU – Literally no two areas are identical
• Within-apartment/house cabling:
– Existing copper (VDSLoGPON), Cat 5e, others (e.g. POF)
• Service level requirement (99.9…%): power back up, MDU vs. SFU type ONT’s
• Aprroach to video services (analog overlay with or w/o set-top boxes, VoIP)

Future upgrade – GPON with C+ optical budget
• Equipment performs above standard (ITU-T G.984.1)
– Optical budget up to 32 dB
– Split ratio up to 1:128
• Currently being deployed
– Typically 1:2 splitter deployed in CO near to OLT keeping 1:64 split ration in OSP
• Main advantage: less active ports upon homes passed
![Page 11: 01 Tyco FTTH Eng](https://reader034.fdocuments.in/reader034/viewer/2022042501/55cf99c8550346d0339f21e7/html5/thumbnails/11.jpg)

Future upgrade - XG-PON
• XG-PON = 10-Gigabit-capable passive optical networks
• Recommendation ITU-T G.987.1
• XG-PON1
– 2.5 Gbit/s upstream path
– Downstream wavelength : 1575 - 1580nm
– Upstream wavelength : 1260 – 1280nm
– Nominal1 (29 dB) and Nominal2 (31dB) at BER of 1E-12
– Split ratio 1:128 to 1:256
– Fiber distance : max. 60km (differential fibre distance of up to 40 km)
• XG-PON2 will be specified in a later phase
– 10 Gbit/s upstream path
![Page 12: 01 Tyco FTTH Eng](https://reader034.fdocuments.in/reader034/viewer/2022042501/55cf99c8550346d0339f21e7/html5/thumbnails/12.jpg)

Mechanical splicing vs. fusion splicing
• Fusion splicer costs more and requires technicians with higher skill set … on the other hand:
– Low material cost per splice (splice protector only)
– Proven performance over time and temperature
• Which technology to go with ? Depends on local circumstances …
• Typically mechanical splicing used only after splitter for drop / in-house cabling
![Page 16: 01 Tyco FTTH Eng](https://reader034.fdocuments.in/reader034/viewer/2022042501/55cf99c8550346d0339f21e7/html5/thumbnails/16.jpg)
page 16
Home passed vs. subscriber
• Home passed / home connected are technical terms – subscriber is marketing issue
• Take rate (subscriber/home passed) ? Ideally 100%, but what if less … ?
– Especially key in areas with competition (like a CATV operator/MSO) and where low take rate is expected for broadband services
– Significant part of investment goes into OLT ports and splitters which can be optimized through optimal splitter positioning
![Page 17: 01 Tyco FTTH Eng](https://reader034.fdocuments.in/reader034/viewer/2022042501/55cf99c8550346d0339f21e7/html5/thumbnails/17.jpg)
page 17
Splitter deployment strategy
• Optical splitters are used in a PON deployment to provide the most effective use of the OLT electronics
– Typically 1 x 64 or 1 x 32 split ratio to overcome optical budget bandwidth constraints especially when planning on video overlay
• Optimum placement of splitters in the network is key for best OLT utilization and reducing operational expenses
• So where to locate the splitters is a critical decision !
• Options (many different approaches, 2 examples):
– Cascaded (distributed) and spliced-in
– Centralized and connectorized
![Page 18: 01 Tyco FTTH Eng](https://reader034.fdocuments.in/reader034/viewer/2022042501/55cf99c8550346d0339f21e7/html5/thumbnails/18.jpg)

Splitter Deployment StrategyCascaded and spliced in
• Concept : Splitters located in FDT and FAT locations and spliced in
• Theory : Cascading splitters in OSP will minimize the amount of fiber needs to be deployed to provide service and splicing saving space and cost
• Reality : Cascaded & spliced in splitters reduce distribution cable material costs, but creates inefficient use of OLT equipment and increase trouble shooting difficulty

Splitter Deployment StrategyCentralized and connectorized
• Concept : All splitters located in FDT locations and connectorized
• Theory : Centralizing the splitter locations for a neighborhood will maximize OLT utilization and provide a single point of access for troubleshooting
• Reality : Provides optimum OLT port utilization in less than 100% take rate builds and provides easy craft access for troubleshooting

Splitter Deployment StrategySummary
• Bottom Line : For the majority of applications a centralized splitter approach may provide the most cost effective flexible network architecture for and FTTP deployment.
Cascaded Approach Centralized ApproachFewer distribution fibers needed More distribution fibers needed
Good for widely scattered rural areas May not be as good for widely scattered rural areas
Smaller FDT needed, larger FAT needed Larger FDT needed, smaller FAT neededDifficult trouble shooting through multiple splitter
locationseasy trouble shooting from centralized access /
splitter locationWorks for 100% take rate deployments Works well for take rates less than 100%
OLT capacity is stranded in less than 100% take rate application
OLT utilization is optimized in all take rate applications
Higher overall splitter loss Lower overall splitter lossMay have a higher failure rate due to more splitter
devices in fieldMay have a lower failure rate due to fewer splitter

Approach in General
• Our portfolio can support both and any possible combinations, yet …
– as a general rule we recommend: placement of splitters centralized and connectorized in OSP as much as it is feasible to reach optimum between fiber use, OLT port utilization and operational expenses
– Also we drive product evolution to reduce number of splices needed to connect homes to FTTH networks, thereby increasing speed of deployment, improving quality of installation and reducing overall deployment cost

China Chooses Connectorisation
• On April, 2008, China’s Minister of Information Industry (MII) released the China FTTH National Standard, which went into effect on October 1, 2008
• Written by China Telecom Design Institution, but influenced heavily by members of Asia Pacific FTTH Council.
• This document advocates a connectorized approach throughout the network, even for feeder cables
![Page 35: 01 Tyco FTTH Eng](https://reader034.fdocuments.in/reader034/viewer/2022042501/55cf99c8550346d0339f21e7/html5/thumbnails/35.jpg)

Why MDU’s ?
• 50% of population living in MDU’s in Europe
• FTTP deployment starting in urban areas
• Limited space for cables and “boxes”
• Equipment installation and cabling has to be fast
– Building owners and tenants often want minimal disruption of their everyday life, and desire FTTP installation in as little time as possible
• Every MDU is different and requires significant flexibility to adjust to local building requirements

Requirements
• ODF to terminate (Outside Plant) fibers spliced to indoor cable in the basement (“istoly”) supporting the FTTH roll out in the service area covered by center “Zugló”
• Estimated cable length between equipment room and splice point at OSP cable entry: 80 meters
• Wall or/and free standing frame
• Interconnect configuration (patch-cords from OLT will be connected directly to OSP fiber through a single adapter)
• Patch-cord entry from top, indoor cable entry from bottom (raised floor installation)
• Efficient slack storage for patch cords from OLT
• E2000/APC connectors
• Option to integrate splitters into the ODF
• Two alternatives:
– Alternative 1: splicing to indoor cable from basement (“istoly”) within the ODF

OMX - Optical Distribution Frame
• Medium density fiber solution. The frame provides mounting locations for termination, splice , vam and storage modules.
• Maximum termination density is 960 or 1440 fibers.
• It is a completely front-facing frame with modular capabilities and allows back-to-back or against wall installation.
• A lower trough allows multiple frames to be mounted in a continuous lineup.
• The bays has 10 module positions and can hold a maximum of 10 termination modules ( 72, 96 or 144 pos) and can ( in another configuration) - hold a maximum of 2 splice modules + 6 termination modules (72 or 96 pos)= 576 termination and splices within 900 mm x 300mm footprint with use of external IMP
• The bay can also hold VAM (value added modules) modules ( = same size as termination odules) .
• The empty bay comes with front doors and end panels are only needed when using external IMP’s (Interbay management panels).
• Height 2200 mm
• Width 600 mm ( MX6-TSF8030 : 800mm)
