Currently, South Asian countries are facing various problems when they are planning to deploy GPON. Most of them are shown in Figure-

FTTx Deployment Problem

Figure: FTTx Deployment Problem

 

Land Lord Problem: Most of the Land Lords do not agree to put ONT in their building premises. Most of them think it as an extra hassle. But, nowadays, awareness is growing and many of them have realized the good sides of GPON technology and some of house owners are willingly request to put BDB in their building premises.

 

Power Backup Problem: Commercial power backup is another big challenge for FTTH service providers. An ONT consumes very little electrical power. If an ONT is ON 24 hours a day for a month, So, it will cost only 0.60$ to 1$. But in our country, most of house owners/ Land lords do not agree. In Bangladesh, load shading is a regular matter; during load shading client will not be able to get service. But, nowadays, most of the clients get power backup from their own UPS or IPS.

Building Distribution Box Problem: Many land lords are not agreeing to install a BDB in his building. After BDB box installation, sometimes BDB key is broken by thieves or bad peoples.

 

Security: Security is another concern issue for FTTx Deployment. ONTs, BDBs and sometimes fiber is stolen.

Heat: In case of Asian country like Bangladesh, heat is a major problem for ONTs. Sometimes service providers have to install ONTs in outdoor. After some months, it is damaged due to heat and dust.

Rats: Sometimes patch cords are cut by rats. Practically, Bangladesh has faced this type of problem continuously.

 

Weak Planning for Deployment: The process of laying fiber involves securing approvals from multiple agencies which is a key challenge. The lack of government intervention in addressing this issue is a major roadblock.

 

The governments in countries such as Finland, Germany and Singapore, have been instrumental in facilitating the roll-out of FTTH networks. For instance, in Germany, the Munich government has laid an underground duct system, which can be used by all utility service providers including telecom operators to provide services to customers. The Singapore government has made it mandatory for every household to allow access to operators for deploying fiber infrastructure. Such initiatives requiring the involvement of municipal corporations have not been taken in Bangladesh.

 

To deploy FTTx in Bangladesh there are some other problem like-

– Charges for laying fiber in towns and cities are very high.

 

-The return on investment in FTTH networks is realized only when a subscriber uses services at the connected location. The returns are impacted when subscribers shift from their locations unlike wireless connections. The FTTH network deployed at premises remains idle until the next user occupies it. Wireless connections allow operators to provide services to customers irrespective of their location.

 

– The high cost of the related consumer premise equipments and optical network terminals is another challenge. Currently, most of these equipments are imported, which accounts for a significant part of overall costs.

 

– Other issues include the efficient transportation of the huge bandwidth, selecting the FTTx access mode and design, ensuring quality of experience for multi-play services, fiber resource saving, long distance coverage, reliable fiber transporting and rational planning of the optical distribution network.

– Currently, the RoW within housing projects or resident welfare associations is controlled by the builder, which generally gives access to one or two operators. Rolling out FTTH in these areas is viable for an operator, if it is guaranteed a subscriber base. Otherwise, competition from other operators reduces the maximum penetration an operator can expect.
