FTTB/FTTH solution.
UTStarcom's FTTB solution using GEPON equipment to implement FTTH will be the ultimate solution for broadband access, and the timing for adopting this solution is maturing. However, the road to building FTTH in full will take a long time. In a certain period of time, the market needs some transition solutions to solve the problems and needs of the existing access network. For the access of enterprise users and the access of residential users of corridors, the existing networks mostly adopt the optical fiber + LAN access mode, and there are weaknesses such as large occupancy of optical resources, multi-level interconnection of LAN, active structure, and poor manageability. The use of GEPON solutions can cover broadband users on a large scale. In addition, its network structure is simple, the passive optical network structure does not need to build an outdoor computer room, is not affected by lightning, high temperature and other factors, improving the reliability and stability of the network. The GEPON network uses single-fiber transmission, which saves a lot of fiber resources compared with the traditional LAN access mode. In addition, the flexibility, security, manageability, and smooth upgrade of the GEPON system network have obvious technical and economic advantages over the full use of Ethernet switch cascading.
UT Starcom has proposed its own FTTB construction mode: First, GEPON+LAN mode. The ONU uses a single Ethernet port ONU device to connect to existing corridor LAN resources and provide end users with broadband access over the LAN. Another mode is to use an integrated ONU device that uses its multiple Ethernet ports to directly provide broadband access to end users. At the same time, GEPON network management system realizes the joint management of ONU and LAN, and solves the problem of management and maintenance of corridor LAN. Therefore, this model will be the ideal GEPON solution for FTTB.
UTStarcom Triple-play Multi-Service FTTH Solution With the market driven by high-bandwidth services such as IPTV and network interaction, the original broadband access bearer network can no longer meet people's requirements for multi-service, high bandwidth and high quality. The access bearer network needs to consider high bandwidth, reliability, QoS guarantee, multicast, and service separation to meet the new value-added services. GEPON technology has great advantages in broadband access, and has unmatched features such as ADSL and LAN. It also meets the multi-service access requirements of FTTH more efficiently than APON, BPON, GPON and MSTP. In the early stage of market FTTH application, GEPON system will be a good choice for new high-end residential areas and existing cell bandwidth expansion. The GEPON system uses a single fiber to solve the access of data, voice and video services, and has the advantages of simple network structure, fewer active nodes, multiple business logic isolation, and convenient provision of other value-added services, making it the ideal last. Kilometer solution.
For FTTH service access, in addition to considering data services, it is also necessary to consider voice solutions, CATV service solutions, and value-added service solutions such as IPTV.
High-speed data service solutions

The ONU101C and ONU1001B provide high-bandwidth data service access for end users from 1Mbps to 1000Mbps. For end users who need to provide triple-play services, they can select ONU200B and ONU300. Access to data services is the same as for existing LAN/XDSL users. -
Voice business solution
There are two types of UTStarcom GEPON voice solutions: one is the traditional voice solution based on V5 access to PSTN network. The solution implements V5-based PSTN voice access through a relay media gateway device. This solution is a good choice in the initial stage of GEPON application, and the number of voice users is small, especially if the softswitch network has not been covered. It has the characteristics of simple network structure, convenient implementation and low cost, and can quickly carry out voice services on the GEPON network. The second access method is a VoIP voice solution based on a softswitch network. It makes full use of softswitch network platform resources, simple network structure and low investment cost. While solving basic voice service access, it can provide rich value-added services in consideration of future support for multiple services. The ideal VoIP solution.
The BBS1000 series OLT can differentiate voice and data services and other services through its uplink port, and divide traffic by different VLANs. In this way, the data service in the service flow of the GEPON system is offloaded to the IP data network; the voice service flow is accessed through the GE/FE interface to the PSTN network or the softswitch network. The ONU200B/ONU800B has built-in IAD and switching functions. It differentiates voice and data services and other services through its downlink port, and divides different VLANs to implement service shunting. In addition, the BBS1000 series OLT and ONU series products have a complete QoS mechanism, supporting Layer 2 COS and Layer 3 TOS/DSCP, thus ensuring the quality of voice services.
CATV Business Solutions
The UTStarcom GEPON system can realize the broadcast transmission of analog video services by using the third wavelength of 1550 nm through WDM technology, thereby realizing the transmission of CATV services in the GEPON system. The OLT side realizes the amplification of the 1550 nm optical signal from the cable television network through the primary or secondary EDFA module, and then multiplexes the two wavelengths of the GEPON (1310 nm, 1490 nm) and the 1550 nm wavelength transmitted by the EDFA through the WDM combiner. It is transmitted to the ONU side of the end user through the ODN network. The ONU can use an integrated ONU with Tripleplay function, such as ONU300, ONU800A, and ONU800B. The ONU has a built-in WDM splitter that separates the 1550 nm wavelength and performs photoelectric conversion and amplification to directly provide an RF electrical interface to the end user.
