Fibtele project input brief
Solution: Data Center Fiber Cabling for 400G & 800G
Solution slug: data-center-connectivity

Quick answer
Data center fibre cabling must be selected from the exact transceiver optical interface—not from link speed alone. Confirm the MDI, fibre type, connector polish and gender, lane map, polarity, reach and complete channel-loss budget before selecting an MPO or LC assembly.

Inputs required before selection
- Switch, adapter, DPU and transceiver manufacturer part numbers
- Ethernet or InfiniBand protocol and required breakout mode
- Optical MDI, lane count, connector polish, gender and key orientation
- OS2, OM4 or OM5 fibre requirement and total channel length
- Patch-panel count, mating points, pathway and cable-management limits

Selection checklist
- MPO-12, MPO-16 or duplex LC interface and actual populated fibre positions
- APC versus UPC polish and connector keying
- Male or female connector and transceiver pin requirement
- Straight or breakout lane map and end-to-end polarity
- Channel insertion loss, mating points, reach and cleaning access

Important limits
- A passive cable does not determine Ethernet or InfiniBand speed, reach or compatibility.
- MPO connectors with different polish types must not be mated.
- The same nominal speed can use different optical interfaces; every design requires the exact transceiver documentation.

Ordering note
This planning brief is for project scoping. Confirm the exact products, interfaces, documents, quantity, MOQ and lead time in the written quotation before ordering.
