FTTH (Fiber to the home) is a transmission method of fiber communication. Specifically, FTTH refers to the installation of optical network units (ONU) at home users or corporate users and is the type of optical access network application that is closest to users in the optical access series except for FTTD. The notable technical feature of FTTH is that it not only provides greater bandwidth, but also enhances the transparency of the network to data formats, rates, wavelengths, and protocols, relaxes the requirements for environmental conditions and power supply, and simplifies maintenance and installation. Primus IT is committed to the research and development of PON technology and provides the best solution for the realization of FTTH.

Primus IT can cooperate in the development according to the special requirements of customers, and provide customers with a complete set of FTTH solutions based on a complete product line.

FTTH Types

  • GPON
    GPON (Gigabit-Capable Passive Optical Networks) technology is the latest generation of broadband passive optical integrated access standard based on the ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces. Considered by most operators as an ideal technology to realize broadband and comprehensive transformation of access network services.
    The asymmetric system only has a downlink rate of 10.3125 Gbit/s, while the uplink rate is still 1.25 Gbit/s. As the first mature next-generation PON technology, 10G EPON technology is in line with network development trends. It has the advantages of large bandwidth, large optical splitting ratio, compatible networking with EPON, unified network management, and smooth upgrade.
    GEPON generally refers to a passive optical network as a pure medium network, which avoids electromagnetic interference and lightning effects from external equipment, reduces the failure rate of lines and external equipment, improves system reliability, and saves Maintenance cost is a long-term technology that the telecom maintenance department expects.
    Symmetrical mode: That is, the uplink and downlink rates are both 10G. The asymmetric mode can be considered as a transitional form of the symmetric mode. In the early stage where the upstream bandwidth demand is less and the cost is more sensitive, the asymmetric mode can be used. With the development of business and technological progress, it will gradually transition to an asymmetrical model.
    Combo, as the name implies, means a combination. Combo PON is a combination of GPON and 10G GPON. It uses two technologies to adopt different bearer wavelengths. The two wavelengths are combined in one optical module to achieve independent transmission of GPON and 10G GPON optical signals.


  • Q: What is Fiber TO THE HOME (FTTH) Technology?

    Speaking of FTTH, we must first talk about fiber access. FTTH belongs to the access network part. The access network is the part from the local office or remote module to the user, which mainly completes the multiplexing and transmission functions, and generally does not include the switching function. Historically, this part was also called the local loop or subscriber loop. According to the definition of ITU-T, FTTH is the entrance of the fiber to the household. There is no copper wire between the end office and the household. The FCC in the United States defines a new meaning for the "H" in FTTH. Family, including small business establishments.

  • Q: What Is The Difference Between Gpon And Epon?

    EPON and GPON have their own advantages and disadvantages. GPON is superior to EPON in terms of performance indicators. However, EPON has advantages in time and cost. GPON is catching up. Looking forward to the future broadband access market, it may not be a substitute for others, but coexistence and complementarity. For customers with high bandwidth, multi-service, QoS and security requirements and ATM technology as the backbone network, GPON will be more suitable. For cost-sensitive, QoS, and low-security customer groups, EPON has become the dominant one.

  • Benefits of Using FTTH

    1. It is a passive network, from the central office to the user, it can basically be passive in the middle;

    2. Its bandwidth is relatively wide, and the long-distance is just in line with the large-scale use of operators;

    3. Because it is a service carried on optical fiber, there is no problem;

    4. Because of its relatively wide bandwidth, the supported protocols are relatively flexible;

    5. With the development of technology, more complete functions have been developed including point-to-point, 1.25G and FTTH methods.

  • Ftth Internet

    In the optical access family, there are FTTB (Fiber To The Building) fiber to the building, FTTC (Fiber To The Curb) fiber to the roadside, FTTSA (Fiber To The Service Area) fiber to the service area and so on.

  • Ftth Solutions

    FTTH is the Triple Play broadband solution that the final telecom network intends to provide. Each household provides one-core or two-core optical fiber, and uses passive optical network PON to provide low-cost, high-stability, and home users who meet the needs of voice, data and image services. The technologies and networks currently in use include E-PON, A/B-PON, G-PON, and WDM-PON.

  • Ftth Test

    Ensuring the high stability of network operations tests the pre-test work of PON service providers, the ability of network monitoring in the service, and the ability to quickly check and repair when obstacles occur, including: PON fiber quality measurement, OLT and ONU network traffic Test, All in One's PON fiber and network test, etc.
