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)

Coexistence Preservation of OSP (power splitters)

Will likely require change in OSP

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

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

Future upgrade - No fork-lift upgrade for 10G GPON

• If splitters are connectorized and centralized, upgrade of passive access infrastructure requires only gradual swap of 1:32 splitters with AWG’s when rolling out DWDM-PON

Filed connectorisation vs. preterminated in factory

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

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

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

1 x 8 Splitter

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

Cascaded vs Centralized Splitter Comparison

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 Case Study

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

Beijing FTTH Trial

• Green Field

• High End Residential Area

• Garden-style MDU

• Phase1, 156 user, 12F feeder cable

• Location: Changping CNC, North part of Beijing, near Great wall

Solutions for MDU’sCase studies

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
