Active & Passive Optics Solution for Optical Access Network
Optical access network is an access network that uses optical fiber as a transmission medium and uses light waves as an optical carrier to transmit signals. It generally refers to the use of optical fiber communication between service nodes and users, or part of optical fiber communication access the system. According to the main types of optical components in transmission facilities, optical access networks are divided into AON and PON.
AON is composed of OLT, ONU, ODT and optical fiber transmission line. Active optical components are used in AON's transmission facilities devices, such as optical transceivers.
PON refers to the ODN between the OLT and ONU, which is mainly composed of passive optical components such as optical fibers, optical connectors, passive optical splitters and optical fiber connectors. PON is a pure medium network, which avoids EMI and lightning impact of external equipment, reduces the failure rate of lines and external equipment, improves system reliability, and saves maintenance costs.
ZKTel's optical access network solution includes SFP, SFP+, XFP, CSFP transceivers, and GPON/EPON, 10G EPON, XG(S)PON ONU& OLT to reach the different requirements from customers.
