How to build an all-optical network park？

May 08, 2021

So how to build an all-optical network? Here we take the campus all-optical network solution as an example:

Unified network: All business forms realize network convergence, and all services can support access and can support interactive intelligent services.

Unified network management: management and maintenance of PON, switches, etc., WLAN, video equipment management, fiber link detection, and fault location.

Adjustable bandwidth and smooth upgrade: Instant speed-up, timing speed-up, flexible method, customer bandwidth can be arbitrarily upgraded from 0~1G+, bandwidth 1G~10G does not affect the ODN network.

The foundation of all-optical network construction: ODN network introduction

ODN: Optical Distribution Network, an optical cable network based on PON equipment, providing optical transmission channels between OLT and ONU, so how to transmit?

GL-E8604T-ATG is a box-type OLT switching device developed by Guanlian Communication. It provides 4 EPON OLT interfaces, 8 10/100/1000 Base-T interfaces, and 4 10G Base-SR/LR/ER interfaces. Only 1U, easy to install and maintain, save space. The OLT adopts industry-leading technology and has powerful functions and QoS guarantees in Ethernet services, supporting SLA and DBA. With a split ratio of 1:64, it supports mixed networking of different types of ONUs, minimizing the operator's investment.

GL-E8010U-FZ type ONU products fully comply with IEEE 802.3-2005 and the China Telecom EPON device technical specification (V2.1). It is operative, manageable and maintainable at telecommunication level, and can provide high speed data service for customers. It has a PON uplink port that connects to office end apparatus through optical fiber.

The transmission process of the all-optical network infrastructure is divided into four parts, the park computer room, feeder section, wiring section, and household entry section. Let's take a look at those connections.

Park computer room: there are ODF, jumper, and splitter.

Feeder section: optical cable connector box, optical cable transfer box, splitter, feeder optical cable

Distribution section: fiber optic cable transfer box, fiber distribution box, optical splitter, and distribution cable

Home entrance section: fiber distribution box, optical cable socket, leather cable

ODN Pipeline Overall Planning: Horizontal Planning

The splitter placement method is more flexible, and can be placed in ODF, SSC, FDT, FAT and other locations, based on the principle of easy placement near the user.

ODN Pipeline Overall Planning: Vertical Planning

The OLT is placed in the computer room of the park. In the case of first-level splitting, the splitter is placed in the optical cross box or fiber distribution box in the basement or corridor of the building. Vertically wired indoor optical cables can be used in the weak current well. 1*32 or 1:64 splitting, the size of the splitter is determined by the number of users covered.
