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 -

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 -
