Product overview
LMC402A is a Black Box micro mini transceiver/media converter (10/100/1000Base-TX RJ-45 to 100Base-FX multimode SC, up to 5km, USB-powered). Optics have to match at both ends and are frequently vendor-coded, so a module that is electrically correct can still refuse to link. Tell us both switch models and we will confirm compatibility before it ships.
Tell us the deadline you are working to and we will say whether it is achievable before you commit to it internally.

What you get ordering this from us
Ordered by part number
LMC402A is what is quoted and LMC402A is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Reach checked against the run
Fibre type, connector and distance are checked together, so the optic suits the path and not just the port.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Questions buyers ask about this part
- Is LMC402A genuine and is the warranty intact?
- Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
- Will LMC402A work in my server?
- Tell us the switch at both ends of the link. Optics are frequently vendor-coded, so a module that is electrically correct can still refuse to come up; we confirm the coding for both ends before it ships.
- Do you accept purchase orders and quote at volume?
- Yes — POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

Specifying a system, not just the part?
Optics and cabling are part of the fabric spec on a cluster build — both ends and the switch have to agree.
