Although 4G construction is booming, fixed-line broadband is still the core business for tier1 Operators. In many places, the lack of channel resources and shortage of optical fibers are the main reasons why FTTH cannot be realized. Nowadays the FTTH bandwidth needs to be improved from 20M to 100M for new streaming services.
However, it has huge challenges as there is no possibility to realize a FTTH bandwidth of 100M on the basis of the original spliting ratio of 1:32 or 1:64. Taking a middle-scale residential community with 1,000 households as an example, optical fibers with at least 32 cores are needed for FTTH full coverage.
In summary, shortage of optical fiber resources is the main problem of FTTH construction for operators.
Sino-Telecom’s WDM PON solution innovatively solves the problem of burst wavelength conversion, which paves the way for quick construction of FTTH.
Sino's WDM PON solution only needs 1 bare fiber cable to bear up to 8 GPON or EPON links, and there is no need to modify the original network topology.
1. Save Fibers: The fiber utilization ratio has been improved 8 times. Only a single-core fiber is needed for residential community with 1,000 households.
2. Overload: Powerful bearer capacity, easily support 8*128 ONU users.
4. Cost Effective: High cost performance.
5. Quick Deployment: The coverage of the residential community can be realized in one day.
6. Long Distance：50Km of PON transmission can be realized.
Two units of OEO6500-I are respectively configured at the CO side and the industrial park. For each unit of OEO6500-I, 2*OEO6500-EWDM service boards and 1*OEO6500-OMUX service board are configured, which successfully realizes the transmission of 8 EPON links over a single-core optical fiber cable. PON technology-based scheme turns things around and wins opportunity to gain market share.
1. FTTH broadband is required for an industrial park in Henan Province.
2. 300 users for phase 1, expansion to 1,000 users in the future.
4. Only two cores of optical fibers.
1. Only one core of optical fiber cable is needed. Another core of optical fiber cable can be reserved for other use.
2. Two units of devices can support 1024 ONU users. Quick deployment enables all the construction can be completed in one day.
3. The overall cost is lower than fiber optic direct drive.
