Gigabit Passive Optical Networking (GPON) Training

GPON Training or Gigabit Passive Optical Networking (GPON) Training course with hands-on Exercises (Online, Onsite and Classroom Live)

A GPON network is capable of transmitting ethernet, TDM (Time Division Multiplexing) as well as ATM traffic. A GPON network consists of OLT (Optical Line Terminals), ONU (Optical Network Unit), and a splitter. The splitter will divide the signal when needed. The OLT takes in all of the optical signals in the form of beams of light from ONUs and will convert it to an electrical signal. OLTs normally support up to 72 ports. An ONU connects to end users and will send their signals back to the OLT. A GPON network can reach up to 20 km and provide service up to 64 end users. GPON utilizes both upstream and downstream data by means of Optical Wavelength Division Multiplexing (WDM).

This GPON Training or Gigabit Passive Optical Networking (GPON) course covers the fundamentals of FTTx GPON and XGPON technologies. GPON is defined by ITU-T recommendation series G.984.1 – G.984.6. GPON can transport Ethernet, and TDM (PSTN, ISDN, E1 and E3) traffic and consists of Optical Line Termination (OLT) and Optical Network Unit (ONU) or Optical Network Termination (ONT) transmission equipments.

XGPON’s Capable passive optical networks (GPON) maximum rate is 10 Gbits/s (9.95328) downstream and 2.5 Gbits/s (2.48832) upstream using different WDM wavelengths such as 1577 nm downstream and 1270 nm upstream:

  • XGPON optical split is 1:128
  • Data formatting is the same as GPON
  • Maximum range is 20 km
