BOM & application review — reply in 1 business day
The 3onedata IMF204-2F series converts four RS-485 ports to two 100 Mbps fiber ports for point-to-point backup or ring redundancy. Its official datasheet lists 0–115200 bps serial baud, 1.5 kVAC isolation, multimode distance up to 2 km or single-mode distance up to 20 km, ring recovery below 20 ms, and separate 12–48 VDC or 100–240 VAC order codes. Selection remains subject to engineering review.

Engineering notes
For the IMF204-2F, engineering review covers physical ports, network topology and ring behavior, protocol-bridge mappings, data model, timing, and the required management layer. Any cross-brand proposal is a candidate replacement — subject to engineering review.
- This is a family page covering two official power-supply order codes
- the exact order code is confirmed at RFQ
- Connector type, fiber mode, wavelength, optical budget and network topology must be matched to the installed link
- The published recovery time applies to the manufacturer's ring function under its specified conditions
- Availability and lead time are confirmed at RFQ
