LINK-PP LS-SC2510-20IN2 XGSPON ONU SFP+ Class N2 9.953G-Tx/9.953G-Rx Class N2 Transceiver Module (Industrial, SMF, 1270nm-Tx/1577nm-Rx, 20km, SC/UPC, DOM)

The LINK-PP LS-SC2510-20IN2 is designed for XGSPON transmission. The module incorporates 10Gb/s 1270nm burst-mode transmitter and 10Gb/s 1577nm continuous-mode receiver. An integrated WDM coupler can separate 1577nm input light and 1270nm output light. The metallic package guarantees excellent EMI and EMC characteristics, which totally comply with international relevant standards.

Ask a Question
  • A:
    Around 2.2W typical, which is more than a GPON ONU because of the higher lane rate and the APD bias. In a standard SFP+ cage with normal airflow it does not need a heatsink, but if your ONU enclosure is sealed and the ambient is 70C, check the case temperature. We have customers running it in sealed boxes with a thermal pad to the housing. by LINK-PP Technical Support
  • A:
    Yes, that is the design intent. XGS-PON was specified to coexist on the same fibre and the same splitter, using different wavelengths. You can run GPON and XGS-PON on the same strand with a coexistence element at the OLT. The splitter ratio is the limit, not the fibre. by LINK-PP Technical Support
  • A:
    It is a power budget class in the XGS-PON standard. N1 is 29dB and N2 is 31dB, so N2 buys you two more decibels of loss. In practice that covers a longer reach or a higher split ratio on the same fibre. If your ODN measures under 29dB, N1 is enough and cheaper. Measure before you decide. by LINK-PP Technical Support
  • A:
    ONU side, the subscriber end. It transmits at 1270nm and receives at 1577nm, which is the reverse of the OLT module. Both come in the same SFP+ package with an SC/UPC ferrule, so they are physically interchangeable and electrically not. Plugging an ONU module into an OLT port will not damage anything but it will not link. by LINK-PP Technical Support

We have 200 of these in service and the failure rate is zero so far. What I would tell a colleague: check the OMCI version your OLT expects before you deploy at scale, because an ONU that does not match will come up and then fail to provision. That is a software issue not a hardware one, but it will cost you a truck roll. Once the profile matched, every unit provisioned first time.

The 1577nm receive path uses an avalanche photodiode, and you can tell from the sensitivity. We measured -28dBm before the first errors, which is what an APD buys you over a PIN at this wavelength. That sensitivity is what lets us keep the existing 1:64 splits rather than re-engineering the ODN during the migration, which would have doubled the cost of the project.

Industrial temperature range is not a marketing line for us, our cabinets hit 68C inside in August and the module has to keep working. Over a chamber run from -40 to 75C the TX power stayed within 1.5dB and the receiver sensitivity degraded by about 1dB at the hot end, which our link budget absorbs. The reported case temperature followed the chamber to within 3C, so our alarms fire at the right point.

Symmetric 10G is the point of XGS-PON and this module delivers it both ways. Upstream used to be the constraint on our business plans, customers bought 1G down and got 200M up. Now we can sell symmetrical and the module does not care which direction the traffic is going. Power draw is about 2.2W, higher than a GPON ONU but inside our per subscriber budget.

Class N2 is the reason we picked this over an N1 part. The 31dB budget is two decibels more, and on a 1:64 split at 20km those two decibels are the difference between a subscriber that comes up in the rain and one that does not. We measured the receiver at -28dBm before errors appeared, which is better than the class requires and gives us margin we did not have before.
