Hello, everyone!
In today’s article, I will explain P2P optical access technology. Let's get started!
P2P optical access is a technology that enables GE, 10GE and FE P2P (Point-to-Point) links. P2P optical access supports the following scenarios:
FTTC/FTTB (Fiber To The Curb/Fiber To The Building),
FTTH (Fiber To The Home),
FTTO (Fiber To The Office),
FTTM (Fiber To The Mobile) and
D-CCAP (Distributed - Converged Cable Access Platform).
This solution is especially interesting for residential communities, it enables triple-play services (data, voice and video) and a flexible FTTx scenario.
The main advantages of this solution are:
High bandwidth. The P2P solution provides higher bandwidth compared to the P2MP (Point To Multi Point) solution. The ideal solution for large business users, who have high requirements.
Lower costs. This solution reduces the total cost of FTTC/FTTB scenarios as it allows more cascaded DSLAMs.
High reliability. This is achieved in a number of ways and is a very important feature for users, especially large business users. The system provides features like smart links, inter-board aggregation, and ring check.
Highly flexible solution. This solution allows the connection of various downstream devices, such as ONU, DSLAM, SBU, and CBU. This implements various scenarios such as FTTC/FTTB, FTTH, FTTO, FTTM and D-CCAP. This allows you to connect with more users.
As we can see in the figure, in order to meet different requirements, OLT must work with different terminal devices (ONU, CBU, DSLAM and SBU) in different scenarios (FTTH, FTTO, D-CCAP, FTTC/FTTB and FTTM).

The FTTH P2P solution provides GE links to every household, providing all services with great bandwidth and reliability. This is especially interesting for large households, villas, etc.
FTTB or FTTC P2P solutions are solutions for DSLAMs in outdoor cabinets on the street or within buildings. They provide GE P2P links, triply play services to a large number of users.
The FTTO P2P solution is a solution for business users. OLT establishes a GE P2P optical connection with the company's SBU device. Different user devices are connected to the SBU. The FTTO P2P solution enables IP PBX, TDM PBX, and private line service.
In FTTM P2P solutions, OLT is connected to CBUs through GE P2P optical link. And the elements of mobile telephony are connected to the CBU.
The D-CCCP P2P solution is a solution where the OLT connects the GE P2P link to the CMC. CMC is connected to CM, where it is switched to coaxial cables. Triple-play services are provided. This solution can replace traditional HFC (Hybrid Fiber Coaxial) solutions with CMTS (Cable Modem Termination System).
This is the end of this topic. I hope you found it interesting and that you learned something new!
Thank you!
