OTN in the era of all-optical network 2.0
The way of using light to transmit information can be said to have a long history. The modern “Beacon Tower” has allowed people to experience the convenience of transmitting information through light. However, this primitive optical communication method is relatively backward, limited...Read more -
How to quickly distinguish between switches and routers
What is a router? Routers are mainly used in local area networks and wide area networks. It can connect multiple networks or network segments to “translate” data information between different networks or network segments, so that they can “read” each other’s data to ...Read more -
What are the main types of ONU equipment used by fiber-optic broadband clients?
1. The ONU equipment used by the client is mainly as follows: 1) In terms of the number of LAN ports, there are single-port, 4-port, 8-port and multi-port ONU devices. Each LAN port can provide bridging mode and routing mode respectively. 2) According to whether it has WIFI function or not, it ca...Read more -
What is the difference between an ordinary ONU and an ONU that supports POE?
Security people who have worked in PON networks basically know ONU, which is an access terminal device used in PON network, which is equivalent to the access switch in our usual network. The PON network is a passive optical network. The reason why it is said to be passive is that the optical fibe...Read more -
How to distinguish optical access network OLT, ONU, ODN, ONT?
The optical access network is an access network that uses light as the transmission medium, instead of copper wires, and is used to access every household. Optical access network. Optical access network generally consists of three parts: optical line terminal OLT, optical network unit ONU, optica...Read more -
It turns out that the application of optical fiber modules is so wide
In the cognition of many people, what is an optical module? Some people answered: it is not composed of an optoelectronic device, a PCB board and a housing, but what else does it do? In fact, to be precise, the optical module is composed of three parts: optoelectronic devices (TOSA, ROSA, BOSA), ...Read more -
Types of fiber amplifiers
When the transmission distance is too long (more than 100 km), the optical signal will have a great loss. In the past, people usually used optical repeaters to amplify the optical signal. This kind of equipment has certain limitations in practical applications. Replaced by optical fiber amplifier...Read more -

Huanet Technologies Co., Ltd. is a provider of telecom network solutions. Huanet’s main business scope is...Read more -
The difference between OLT, ONU, router and switch
First, the OLT is an optical line terminal, and the ONU is an optical network unit (ONU). They are both optical transmission network connection equipment. It is the two necessary modules in PON: PON (Passive Optical Network: Passive Optical Network). PON (passive optical network) means that the (...Read more -
Is there a difference between FTTB and FTTH?
1. Different equipment When FTTB is installed, ONU equipment is required; FTTH’s ONU equipment is installed in a box in a certain part of the building, and the user’s installed machine is connected to the user’s room through Category 5 cables. 2. Different installed capacity FTTB is a fiber optic...Read more -
Analyze the four major requirements of data centers for optical modules
At present, the traffic of the data center is increasing exponentially, and the network bandwidth is constantly upgrading, which brings great opportunities for the development of high-speed optical modules. Let me talk to you about the four major requirements of the next-generation data center fo...Read more -
LightCounting: The global optical communications industry supply chain may be divided into two
A few days ago, LightCounting released its latest report on the status of the optical communications industry. The agency believes that the global optical communications industry supply chain may be divided into two, and most of the manufacturing will be carried out outside of China and the Unite...Read more
