Length: 2 Days
GPON Training, Gigabit Passive Optical Networking and XGPON Training
GPON Training, Gigabit Passive Optical Networking Training. A 2-day GPON training course including GPON, XGPON 10 Gigabit systems. and NG-PON2.
Gigabit Passive Optical Networking course covers the fundamentals of FTTx GPON, XGPON and NG-PON2 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 equipment.
Learn about:
- The basics FTTx technologies
- Principles behind Passive optical networks (PONs)
- Architectural principles of access networks
- Analysis and planning, topologies, site types, and Fiber Termination Points
- GPON general characteristics
- GPON FTTH platforms
- Capable passive optical networks (GPON); XGPON, XGS-PON and XGS-PON2
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
Physical (PHY) layer of XGS-PON is based on existing specifications and it operates within the same optical transmission windows (1260 nanometers (nm) to 1650 nm). The PHY compatible transmission convergence (TC) layer allows for co-existence of XGS-PON with the earlier XG-PON and NG-PON2 that uses TWDM.
XGS-PON is based on ITU-T G.9807.1 :
- Operates over a downstream wavelength of 1577 nm and an upstream wavelength of 1270 nm
- Further compatibility over the optical distribution network (ODN) with existing GPON that uses different wavelengths
- XGS-PON also has the ability to operate on GPON wavelengths
- 1490 nm in the downstream and 1310 nm in the upstream
- XGS-PON PHY also leverages time division multiplexing (TDM) and time division multiple access (TDMA) methods to accommodate XG-PON compatibility
- Coexistence of XGS-PON and XG-PON
- XGS-PON supports up to a 1:128 split ratio in the ODN, as well as 1:64, 1:32 and 1:16 split ratios
NG-PON2 (ITU-T G.989):
- NG-PON2 uses time and wavelength division multiplexing (TWDM)
- Using TWDM with NG-PON2 allows operators to supply a 40 Gbps symmetrical service
