Comparison between all-optical network and traditional network

May 08, 2021

1. Network structure

POL All Optical Network

Bandwidth guarantee: single PON port 2.5G bandwidth; during peak hours, the effective utilization of outlet bandwidth is >92%

Clear hierarchy: coverage area & number of users does not affect secondary structure

Simple maintenance: OND network is maintenance-free; OLT directly manages ONU

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.

Smooth upgrade: bandwidth expansion on demand; 1G→10G, no need to change all-optical network

Traditional network stack

Bandwidth waste: single port 1G bandwidth; during peak hours, the effective utilization rate of the outlet bandwidth is <60%.

Hierarchy of chaos: Hierarchy increases with the expansion of scale, complicated and chaotic, complicated maintenance, upper equipment cannot manage lower equipment, manual management is difficult.

Difficulty in upgrading: adding staff, decreasing bandwidth; upgrading bandwidth network needs to be relocated.

2. Wiring advantages

optical fiber

(1) 30 years of optical fiber life, glass core/plastic core, corrosion resistance.

(2) Ultra-long transmission distance can solve many wiring difficulties.

Copper wire

(1), copper wire wiring takes up a lot of pipeline resources

(2) Generally, it is easy to age in about 10 years and needs to be redeployed.

(3) The transmission distance is limited to 100 meters.
