How to bring optics into the gateway without a media converter?
There is optics from the provider, the multimode enters the server (gateway) through the converter (from optics to copper), what would you recommend a budget network card with an sfp module to directly link to the gateway and did it also work?
There is an opinion that the media converter is buggy periodically, we want to get rid of the extra node.
Another question about transceiver compatibility is interesting, which transceivers are compatible with which network cards (for example, Cisco, Extreme Networks, HP, Nortel, Planet, D-Link, 3com), I heard that cisco transceivers, for example, except in ciscos, will not work (true or no, I do not know).
Interested in the opinion of people who have already done this, and not passing writers.

Answer 1

1. Network cards with gigabit SFP ports are a common thing. For the system to work, it is necessary that the channel speed in the optics is supported by the network card (roughly speaking, if the provider ships 100Mbit FastEthernet via optics, and the selected network card can only work on 1Gbit GigabitEthernet, then the system will not take off).
Specify the speed of the channel - we can advise the network card.
Comrade Opium has already written to you about wavelengths, this is not cancelled.
2. By transceivers. As opium already said, cisco is the pickiest. Although from my own experience I can say that there are Juniper QFX switches that also require “their own” firmware, and many HPs are also capricious.
The Taiwanese (DLink, Zyxel, Planet) eat everything you put in.
Still sometimes native Intel network cards with SFP ports are capricious.
But, as opium rightly said, modules are quite easy to interchange.

Answer 2

If you have a gigabit or a hundred megabit link, look at the frequencies of the converter, and does it work under one fiber or not? The LNBs transmit and receive at different frequencies, and the LNBs are therefore sold as a pair, A and B LNB. Depending on the frequencies, select the spf module, but in general this will not reduce the number of nodes, you just have a module instead of a converter. There is more savings on space and wires. The binding by manufacturer is mainly for cisco, these HP, Nortel, Planet, D-Link, 3com manufacturers usually do not have a hard binding to the modules, and for cisco, the left modules are flashed quite cheaply and they become cisco compatible.

Answer 3

If there is also a converter on the other side, it will not work with a high probability, so as not to point your finger at the sky, which converter is used now?

Answer 4

I didn’t answer for a long time, because I wanted to look at the other side of the coin: I
went to the local “provider”, looked at what was there from optical equipment, he had several “3com” switches. They even let me hold one of the unused 3CSFP91 transceivers. I
found the following description:
Optical gigabit mini-converter for 1000BASE-SX interface with LC connectors. It is installed in a special GBIC slot of 3Com switches.
Characteristics:
Connector LC
Modal Bandwidth (MHz-Km) 160-500
Transmission distance 220-550 m
Wavelength (nm) 850
Optical fiber:
Cable type MMF
Diameter (Micron) 62.5, 50
Power:
Output (db / m) -9.5 to 0
Input (db/m) -17 to 0
