Standards Compliance
- ITU-T G.984.2 / G.984.2 Amendment 1 (GPON)
- ITU-T G.988 (OMCI)
- SFP MSA (SFF-8074i)
- SFF-8472 v9.5 (DDM)
- FCC 47 CFR Part 15, Class B
- FDA 21 CFR 1040.10 and 1040.11
- IEC-60825 (Class 1 laser safety)
Notes
- The GPON-ONU-STB+ is described as a dual-mode ONU stick: it supports both GPON and EPON ONU OAM and will automatically establish a link with either a GPON OLT or EPON OLT.
- Pin 7 (RateSelect) is repurposed for Dying Gasp detection (input, active low).
- Data input is LVPECL compatible, DC coupled internally.
- Receiver is APD-TIA based, providing higher sensitivity than the non-MAC CLB+ variant which uses Super-TIA.
- This is a complete "PON on a Stick" — an entire FTTH ONU in a slightly oversized SFP that can be plugged into networking equipment (switch, router, PBX, etc.).
