After some research I found that the normal length limitations of OM1 optic fiber have been extended quite a bit. The OM1 62.5/125 multimode limitations have been extended from 275 meter up to 2km on 1Gbps and from 33m up to 300 meters on 10Gbps. Or more...?
Do people here have experience with adapters that extends the length almost 10 times from original specifications? What is the longest 1Gbps and 10Gbps over OM1 fiber people got? Have anyone been able to get 2km for 1Gbps and 300m for 10Gbps stable? What equipment was used?
Below is a list of parts I found.
1 Gbps SFP modules
Here are some modules I found. Most are not specific. Only one I found says support 2km on OM1. All of them is 1310 nm.
OM1 - 2km
Transition Networks TN-SFP-ESX6 Gigabit Extended MM SFP 1000Base-SX 1300nm Mmlc 2km 62.5micron (TN-SFP-ESX6)
Only mentions MMF multimode

Only mentions OM2 50/125µm multi-mode
Generic Compatible 1000BASE-LXL SFP Multimode 1310nm 2km Transceiver (OSP1250-312xCR)

2.5 Gbps SFP modules
There is also few 2.5Gbps SFP modules. I thought they would support longer distance than 10GBase-LRM modules but specifications says no. All is 850nm.
Only mentions MMF ... Up to 300 meter.

For 10Gbps the 10GBase-LRM (Long Range Mode) standard at 1310nm officially extends to 220 meter or 720 ft. 10GBase-LRM over OM1 and OM2 multimode apparently needs a "mode conditioning patch cord" to work. All is 1310nm except Ubiquiti that is 850nm..

How to achieve a robust 10g Ethernet link, using old multimode fiber OM2 / OM1
For a few weeks running now, we have been covering the subject of multimode optic installations, something which used to be standard practice in very many 20-year old buildings. In those days, they were mainly of the OM1 (62,5/125) and OM2 (50/125) type, which were widely used at the time, for...
