    ZKTel is major in EPON OLT,ONU, range from 1.25g to 10G.

  

    Ethernet in the first mile (EFM) refers to using one of the Ethernet family of computer network protocols between a telecommunications company and a customer's premises. From the customer's point of view it is their "first" mile, although from the access network's point of view it is known as the "last mile". A working group of the Institute of Electrical and Electronics Engineers (IEEE) produced the standards known as IEEE 802.3ah-2004, which were later included in the overall standard IEEE 802.3-2008. Although it is often used for businesses, it can also be known as Ethernet to the Home (ETTH). One family of standards known as EPON uses a passive optical network.

The use of a passive optical network is a common example of fiber to the home.[23]
