A:
Yes. FEC is a function of the switch port, not the optic. Enable RS-FEC for 25G as required by 25GBASE-SR, and run 10G without FEC or with BASE-R FEC depending on your platform. The module passes traffic transparently in both modes, and we test both 10G and 25G before shipping. By

A:
No measurable contribution. The module is a physical layer device with no buffering or retiming beyond the standard CDR, so it adds only propagation delay. In our own testing the link budget and BER stayed clean at 25G with RS-FEC, and customers running eCPRI fronthaul report no timing degradation after swapping to these. By
admin
A:
For 25G you need an SFP28 cage and a switch port rated for 25G. For 10G it will run in an SFP28 cage configured to 10G. In a plain SFP+ cage it is mechanically compatible, but we recommend checking with the switch vendor first, because some SFP+ ports do not supply the required clock and I2C behaviour for a dual rate SFP28 module. By
admin
A:
The module is rated for 70m over OM3 and 300m over OM4. In a real installation with two patch panels and several connectors, plan for about 55 to 60m on OM3 and around 250 to 270m on OM4. Clean the end faces before mating, because contaminated OM3 connectors are the usual cause of 25G link errors at these distances. By

Used as a cheaper alternative to active optical cables for rack to rack links. The SFP28 form factor fits our existing LC patch fields, which the AOCs did not.

850nm VCSEL over OM4 to 300m is what we needed for a cross aisle run. Measured receive power is healthy and the DOM page in our switch shows real values.

We had a legacy 10G core and a new 25G access layer during a phased migration, so a dual rate SFP28 was the practical answer. These ran at 10G on the old line cards for six weeks, then we moved them to 25G ports on the new switches. Same modules, no re-coding, no compatibility warnings. That flexibility saved us from buying twice.

Our 5G fronthaul cabinets use 25G eCPRI between the DU and the RRU aggregation switch. These SFP28 850nm modules have run for four months across 36 links with no dropouts. Temperature inside the cabinet peaks at 52℃ and the modules report around 48℃ internally, so there is margin. No added jitter in our timing tests.

We had a run of about 60m on OM3 and these handled it easily. Good to know the 70m OM3 rating is real, since some vendors are optimistic about multimode reach.

Used for a small edge data center with a 25G spine and 10G legacy storage. Both speeds worked on the same module, which is exactly why we chose it. DDM shows temperature and RX power and our NMS picked it up. Physically the LC connectors are fine, though the housing is lighter than the metal bodied OEM parts.

Bought 24 for a lab expansion. All passed our 25G BER test at 72 hours, which is stricter than we usually apply to short reach optics. The SFF-8472 DOM implementation is standard, so our existing polling scripts worked unchanged. Only small thing, the pull tab is stiff on new units and takes a firm tug.

Deployed 60 units across three racks for a GPU cluster interconnect at 25G. The short 850nm reach is fine because our longest fibre run is 85m. What I checked carefully was consistency, TX power across the batch varied by less than 1dB and none of the modules threw a DOM alarm in the first month. Cages seat firmly with no rattling latch.

We run a mix of 10G and 25G ports in the same row, so this dual rate part simplified our spares. On OM3 we kept runs under 65m and everything is stable, on OM4 we pushed one link to 280m with no issues. Low power draw and the price is roughly half of what the switch vendor quoted.

I tested these against a couple of OEM 25G SR optics on 90m of OM4 and the receive power was within 0.5dB, which is more than close enough for our needs. The 10/25G dual rate is the reason we standardized on this part, during our switch migration we ran the same module at 10G on old gear and 25G on new gear. Fewer SKUs in the store room is a real win.

Optics have been reliable at 25G, but the shipping box had no padding and three modules were loose in the bag. Two had scuffed latches. They still linked, but for a data center order I expect better packing.

We refreshed a small data hall and used these for every 25G leaf to server link. 48 modules over OM4, longest run 118m, all came up with RS-FEC and zero symbol errors after burn in. The dual rate option was genuinely useful, two older servers still run 10G and we did not have to keep a separate SKU. DOM reports TX power and temperature properly.

For a 300m OM4 run between two buildings on campus we could have used single mode optics, but these 850nm SFP28 modules were cheaper and the multimode backbone was already there. Link came up at 25G with RS-FEC, receive power around -3dBm, and we push backup traffic over it nightly. Clean and simple.
