What's the difference between a GPON and a cat?

- Jun 29, 2019-

GPON and EPON are optocat terminals. The two optocats are not universal and there is no difference.
Photocats: Optical modems, also known as single-port optical terminals, are a three-piece set of optical fiber transmission devices developed for special user environments. They consist of sending, receiving, controlling, interfaces, and power supplies. The device adopts a large-scale integrated chip, with simple circuit, low power consumption, high reliability, complete alert status indication and perfect network management function.
Ordinary cats: refers to ADSL cats, light cats: refers to cats with PON optical fiber into the house. The fundamental difference between these two cats is that one is attached to the telephone line to enter the home, and the voice separator is in line with the broadband; PON Cat is the terminal equipment ONU of EPON and GPON. It can implement first-line telephone voice service, broadband Internet access service and ITV digital TV service. It can be realized without adding any separators. There are also great differences in bandwidth rates. ADSL cats can only operate at a maximum of 6 Mbps limited by copper cable transmission, and ONU Opticon terminals can operate at a maximum of 100 Mbps rate by the user himself. The line ADSL is a copper cable transmission and the PON device is a fiber optic transmission. Therefore, the biggest difference between light cats and ordinary cats is the difference in transmission speed. The left side of the picture is a light cat and the right side is an ordinary cat.

imageGPON(Gigabit-Capable PON) technology is based on the latest generation of broadband passive optical integrated access standards of the ITU-TG .984. X standard. GPON has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interface. It is regarded by most operators as an ideal technology to achieve broadband access and comprehensive transformation of network services.
