Access and Backhaul Consolidation with NG-PON2 Access and Backhaul Consolidation with NG-PON2 Presentation Transcript

  • © 2014 ADVA Optical Networking. All rights reserved. Confidential.4 NG-PON2 Main Variants • Shared vs. Expanded Spectrum (co-existence w/ legacy PON generations) • TWDM vs. PtP WDM • 4, 8, more wavelength pairs • TWDM 2G5 vs. 10G (US and/or DS), PtP WDM w/ 1G, 2G5, 3G, 5G, 6G, 10G, … • Power split (preference) vs. filtered ODN • N1 vs. N2 vs. E1 (vs. E2) reach options • More (DFB vs. DBR lasers, cyclic AWG vs. TFF, …) Loss N1 N2 E1 E2 Min. 14 dB 16 dB 18 dB 20 dB Max. 29 dB 31 dB 33 dB 35dB
  • © 2014 ADVA Optical Networking. All rights reserved. Confidential.5 Shared-Spectrum NG-PON2 • Co-existence of TWDM and PtP WDM (shared spectrum) • Potential co-existence w/ G-PON, RF, XG-PON1 (brownfield and greenfield) • Up to 8 wavelength pairs for TWDM (8  32…64 users) • Up to 16 PtP WDM wavelength pairs possible (best practice could be 8) • Total split 256…512 will most likely require Reach Extender (27…31 dB PS IL) … PtP ONU x … … TWDM OLT Port 1 TWDM OLT Port 4 PtP WDM OLT 1 PtP WDM OLT N TWDM ONU n … 1:N WMWM CoexistenceElement Power Splitter

Confidential.6 Expanded-Spectrum PtP WDM • No co-existence w/ TWDM, G-PON, XG-PON1, and/or RF overlay • Considered greenfield only • Overlap with ITU-T SG15-Q.6 G.metro pWDM / WDM-PON • Will most likely have 40…48 WDM channel pairs • Power-split or filtered ODN (filters shown) • Full-band tunables lasers WM PtP WDM OLT 1 … PtP WDM OLT N … WM PtP ONU 1 PtP ONU N Filter

  • © 2014 ADVA Optical Networking. All rights reserved. Confidential.8 NG-PON2 Applications • Residential access – shared, TWDM • VDSL2 (FTTCab) / G.fast (FTTdp) backhaul – TWDM or PtP • Broadband business access (shared or dedicated) – TWDM or PtP • Mobile backhaul (MBH, D-RAN) – TWDM, PtP • Fronthaul (MFH, C-RAN) – dedicated, PtP • Hybrid Fiber/Coax (HFC, 2nd-ary Headend backhaul) – TWDM, PtP

Confidential.10 Wireline Backhaul DPU : Distribution Point Unit • In order to increase copper bandwidth, fiber must get to the distribution points • The next wave of wireline backhaul • NG-PON2 supports all wireline backhaul bandwidths and distances Local Exchange New CO AGS DPU Cabinet ONU G.fast <250 m ADSL <7 km VDSL <1.5 km CP WM CP CP OLT
  • © 2014 ADVA Optical Networking. All rights reserved. Confidential.11 HFC, incl. Backhaul • In order to increase copper bandwidth, smaller clusters and more fibers are needed • This increases the Fiber part in HFC • NG-PON2 may support this, however, there was almost no input from cable operators to its standardization CMTS : (Modular) Cable Modem Termination System Optical Node 2nd-ary Headend Opt.

  • © 2014 ADVA Optical Networking. All rights reserved. Confidential.14 Conclusion • NG-PON2 can come in many different variants • It can support various access, backhaul and fronthaul applications, including the network / active-site consolidation for these applications – Structural Network Convergence (ref., e.g., EU FP7 IP COMBO) • It can be used by any type of operator for the respective applications
