<oxcenture.eranga@gmail.com>Dear @Manjula Rathnayaka / @'Anupama Bandara (Contractor -OS',
As this site needs to be attended urgently, there are a few issues that need to be cleared before we proceed:
- Materials from AC Warehouse are ready for collection and will be collected today.
- Materials from Advatis are not yet ready. These need to be collected today if the site is to be attended tomorrow.
- Some required materials have not been allocated, specifically:
- 1 No. UBBPe4 card
- 6 Nos. SC/LC 3 m single-mode patch cords (Not even included to Required material List)
- Allocated SFP type is not suitable to establish the link, as the optical distance is greater than the supported range of the provided SFP.
- Allocated SFPs type :
Material | Material Description | Vendor | Speed (Gbps) | Base | SM/MM | Wavelength (nm) | Distance (Km) |
1000019511 | HUA LTE Optical SFP 1310NM 9.8G SM | Huawei | 10 | SM | 1310 | 1.4 |
- Required SFP type: As per the OFN team, the fiber path distance is more than 1.8 km. Therefore, suitable SFPs are required to support this distance.
- Confirmation is requested to proceed with purchasing the AC to DC converters. Please advise so we can proceed.
- As per the WO, the power method was a rectifier system; however, it has now been changed to AC to DC converters (for your information).
- Sinnakkulam-VA0056 is an OO (Hutch) site. Access permission has been requested, and support is needed to obtain the approval.

<oxcenture.eranga@gmail.com>Dear @Manjula Rathnayaka,
We have completed the installation at VA9001 – Vavuniya OmegaLine EBTS. However, only two sectors are currently connected to the BBU pooling site (Sinnakkulam – VA0056), as only one pair of fibers was provided for OFN patching.
As per the WO, two fiber pairs (4 cores) were required for three RRUs — one RRU to be connected directly and the other two via cascading. Since only one fiber pair was available, we connected the cascaded RRUs and provided connectivity to the OMCR for configuration.
Please check and advise.
Dear @'Thushan Weerasooriya'/@Subash Manchanayake/@'Anupama Bandara (Contractor -OS'
This is for your attention.
