Invitation for Application to Build Broadband Optical Network

and Provide Internet Access Connectivity Services in 8 Districts of Province 2


Clarification on IFA No. 05/NTA/2073/074






FTTH Number of access port (342000 & 328000) is more than 63% of its total number of household and practically is it not possible or viable to build that much of capacity and actually the provided number of OLT can't handle up-to that number of access ports.

Maximum 30-35% active port occupancy ratio is consider during calculation. So number is reasonable.



As per RFA document there is assumption that the 1 PON port can carry up-to 128 connections but it is not possible in practical field, it is only possible inside the lab. As per the experience we can maximum go up-to 32 connections from one PON port in rural areas.

SLO are free to recommend the optimal design in the basis of requested quantity in the RFA document & Clause 14.0 FFTH Roll-out Guidelines.


As per RFA NTA will provide subsidy as per ONT; the SLO can claim its subsidy once after every 30000 subscriber and we think this number is too huge and recommend to reduce the number up-to 1000.

NTA will provide subsidy as per ONT; the SLO can claim its subsidy once after every 5000subscriber.


As per RFA only the ISP/NSP is eligible if they are currently providing the service to 10,000.00 end users. Is it consider the number of connections provided to out of valley only and it will include all connections including inside Valley?

Total no. of active subscribers should be 10,000 including inside & outside valley.


The local level election is still to perform in province 2 and now most of the ward offices are in operating jointly. does this affect the number of end user.

 If equipment changes due to change of number of ward or local body, then SLO can claim on BOQ unit rate and subsidy pro-rata   basis.  


Government provisioned that there will be at least one health center in a ward office, what if that process might get delay ?

 If equipment changes due to change of number health centre, then SLO can claim on BOQ unit rate and subsidy pro-rata   basis.  


Is there any possibility to use the existing optical fiber network?

Yes; if it meet the technical specifications & standard mentioned in the RFA.


Is there any particular location to underground the Optical fiber or we can perform as per our convenient?

Except special decision of Government and NTA,  SLO is free to roll-out whereever feasible & required.


Please clarify on ODN cost per port?

ODN Deployment cost refers to all the cost incurred to build the network that includes all other cost beside Equipment such as labour cost and etc.


Does NTA bare the Pole rental charge?

 No, SLO have to manage rental charges of Pole, land and others.


No Specifications were mentioned if in case to erect the poles to pull the fiber where the poles are not available.

 SLO have to manage Pole, land and others.


What are the options for Bandwidth provisioning and customer profile management? Do we need to implement BRAS/BNG and OSS/ BSS ?

SLO are free to use and upgrade their existing BRAS/BNG and OSS/BSS and have to maintain.


The specification that mentioned in 10.15 of Annex 10 is not comply with the NMS and it will incur huge cost with third party vendor. Does this relevant for this project.

Monitoring & Visibility of passive optical network is a vital part of efficient network management , operations. SLO can provide any 3rd party application for this purpose if the NMS of active components cannot support this function.


Earthing system <2 ohm can't be done practically so need to revise to <5 ohm, please verify once.

It should be <2 ohm.


Can we maintain the redundancy on MPLS level or need to be done in OLT level ? If MPLS level, we need more routers.

Redundancy and MPLS should be enable and Maintain by OLT & its uplink interfaces. Operators are free to recommend the optimal design with reference to the quantity mentioned in the RFA.


Do we need to pay 2% RTDF and 4% Royalty?

Need to pay as per rule.


According to the Annex 10 regarding router specification it is mentioned that in 9.24 the proposed router shall support 5 level hierarchical QoS scheduling, but none of the vendor's router is capable enough to support that feature please clarify. Is that 5 level HQoS requirement is needed in future or in first day ?

Minimum 3 Level HQoS support will be accepted but it is a future requirement not need in day 1.


As per RFA client end drop wire should be 2 core but as per market practice we should go with single core optical fiber because of fast installation and after sales support process.

SLO can propose both (single core and two core). If SLO proposal is better than as specified in RFA, then SLO’s proposal will be accepted.


It is large project the provision of Join-Venture will be appropriate.

Joint-venture (JV) shall not be provisioned at this stage.


Can allow somewhere wireless network?

No, SLO has to build only Optical Network.

Item Description



Annex- 10 Page - 17


Should Support L2, L3, IP/MPLS, VPWS, VPLS, Layer 3 routing protocols OSPF,IS-IS,BGP

L3 function will perform on the router which is uplink device of OLT, since L3 function is already inbuilt in OLT, we feel this would be stating the obvious & not necessary to be specified explicitly.


Annex- 10 Page - 17


Should support or have clear roadmap to support SDN and NFV in same unit

NFV and SDN feature are still under discussion on even in Europe, USA & EMEA, the standards are still being devised & not finalized yet; If we include these features the project cost increases exponentially, without adding significantly to the current user experience, hence we would request you to reconsider the utility & value added along with the economics of the scale to excluding these for the current scope of the project.


Annex- 10 Page - 16


The proposed equipment shall be able to detect and isolate the rogue ONTs

It‘s very important to detect and isolate rogue ONT in real time, because any malevolent actors, including hackers may easily access to the network via rogue ONT resulting in the breakdown of the entire network in seconds; Hence, we think it is prudent to have real time capability to address the risk.


Annex- 10 Page - 19


The proposed server shall be 19” rack-mountable with redundant power supplies, redundant 15k SAS hard disks and redundant Gigabit network interfaces.

If we plan for redundant 15k SAS hard disks and redundant Gigabit network interfaces, the cost of NMS management becomes very high & does not make it economically feasible, hence we would request you to consider removing the clause.


Annex- 10 Page - 20


The NMS must maintain the database of Fibers, Fiber splice points, Fiber enclosures, Fiber loops, Fiber routes, Fiber types, Fiber cores, tubes, Distribution

NMS is used to manage active devices and inventory system, while (OSS) is used to primarily for ODN device management. In the current scope, NMS is not the best or optimized solution for the management of all the factors mentioned in the clause. Since, NMS is not




Splitters, Splitter distribution ports, Poles, OLT/ONT location and provide complete visibility of Fiber network in Google earth or GIS maps. This can be on the same NMS or another 3rd party application and provide near to real-time visibility and fault predictions of passive network.

Required to support ODN device management; Since the NMS isn’t the best solution as intended in the clause, we would request you to consider removing this clause.




The OLT must support 1+1 10GE protection uplink

To ensure a reliable and stable service, the OLT device should have redundant service inbuilt in it. So, we would request you to consider a solution with OLT with 1+1 10GE protection uplink.




The OLT should support C++ SFP with receive sensitivity should better than -35dBm to cover maximum 40km distance;

This project is for the universal broadband service and the service is being provided for every household in province 2, which includes high/medium/low population area. In some location, the ward office/school are located far (>20km &<40km) from OLT central office. To reduce the broadband access cost of these area, the C++ SFP is required to cover maximum 40km distance. So we would request you to consider a solution the same in mind.




The ONT shall support variable- length OMCI

In this project, as the system will access more 300k FBB subs, comparing fixed-length OMCI solution, it will save 50% of time for ONT upgrade, it is required to support variable-length OMCI feature. So we would request you to consider a solution with the added variable-length OMCI feature in mind.




The proposed ONT shall support IPv6 ready logo certification.

The IPV6 feature is the new generation of technology & will ensure that the infrastructure is protected against technology obsolescence. Since this will be the way the ISP infrastructure will be moving to in the future, it is essential that it should be added & certified by international organization as being IPV6 Ready or as a part of the WIFI Alliance. We would request you to consider adding this critical requirement in the clause.
