What is an optical module in the perception of many people? Some people answer that 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: an optoelectronic device (TOSA,ROSA,BOSA), an optical interface […]
What are the application Scenarios for Fiber Optic Module (SFP)? Read More »
Let\’s explore the key technologies of GPON. The key technologies of GPON include Ranging, Upstream dynamic bandwidth allocation, and Downstream AES encryption. Ranging Why do we need to measure the distance? The distances between ONUS and OLTS are different. The transmission time of optical signals on the optical fiber is different, and the time when
GPON (Gigabit Passive Optical Network) is the largest fiber access technology for delivering gigabit Internet to businesses and homes. It\’s an all-fiber technology that can be used to build Fiber to the Premises (FTTP) networks that connect subscribers to local ISPs. GPON is the most fiber-efficient option for FTTH networks, providing a cost-effective method to

Reference architectures of fiber access networks defined by ITU-T Recommendation G.984.1 allow the use of both fiber and copper cables as transmission mediums, with a possible transition between them in the middle of the access loop. This architecture is known as fiber to the x (FTTx) because optical fibers can reach various locations in and
Take a moment to think about how your Internet usage has changed in the last few years. The average person is doing and expecting a lot more from their Internet like increased interactivity, rich media, and uploading and downloading pictures and videos. Increasingly large files are moving across the cyberspace network, and experts expect that
In the optical communication process, it is the access network with light as the transmission medium, replacing copper wire, used to access each home, optical access network (is our home wifi). Optical access network generally has three parts: optical line terminal OLT, optical network unit ONU, optical distribution network ODN, where OLT and ONU optical
