Ask a Question
  • A:
    The upstream window is defined around 1270nm so it sits clear of the 1310nm band used by GPON upstream, which lets both coexist on one feeder through a combiner. The tolerance is a few nanometres either side of centre, and a DFB without a cooler stays inside that across the rated temperature range. It would not stay inside a 50GHz DWDM grid, but that is not what this window is for. by LINK-PP Technical Support
  • A:
    No. It is an XGS-PON module, and a combo card will only bring it up on the port configured for that standard. Plugged into a GPON port it stays dark because the line rate and the framing do not match. The physical connector is the same, which is exactly why the mistake happens on a busy card with sixteen identical looking ports. by LINK-PP Technical Support
  • A:
    Yes, a continuous source measurement will mislead you. The laser is only on during its granted slot, so a plain power meter reads a duty cycle weighted average that looks several dB low. Use a gated meter triggered from the grant pattern, or a scope with an optical head. Our first acceptance run flagged three good modules as weak before we changed the method. by LINK-PP Technical Support
  • A:
    On paper it is marginal and in practice I would not. A 1:64 splitter costs about 20.5dB, twenty kilometres of fibre about 5dB, and splices and connectors another 2 to 3dB, which lands near 28dB against a 31dB class. That leaves almost nothing for ageing and dirty connectors. Use 1:32 on the long lines and keep 1:64 for short ones. by LINK-PP Technical Support

Four stars, two of the twenty had SC ferrules that needed a second clean before the loss came down. After cleaning they were fine.

The module stays in the ONU and never gets touched after install, so the SC connector is the only field interface.

Installation is the same as any pluggable, which is the point. The ONU has a cage, the module slides in, and provisioning happens from the head end. No switches, no local configuration, nothing for a field tech to get wrong on a ladder.
