Specifications
Confirm model, interface type, rate, power, airflow and software version before ordering.
Selection answer
MFA1A00-C010 is the 10 m ordering code in the retained MFA1A00 100GbE QSFP28 active optical cable series. It is a candidate for a fixed short inter-rack or equipment-row link when both endpoints explicitly support the OPN and the planned route can protect the integrated cable. Connector shape and nominal rate alone do not establish compatibility.
Specification baseline from the retained record
| Decision item | Retained evidence | Project check |
|---|---|---|
| Ordering code | MFA1A00-C010 | Match the full OPN on quote, label and received item |
| Nominal length | 10 m | Measure the installed pathway, service loop and cabinet entry |
| Network interface | 100GbE, QSFP28 | Confirm both endpoint models, port mode, firmware and FEC |
| Cable technology | VCSEL-based AOC with multimode optical channels | Protect the integrated assembly; do not plan field termination |
| Series details | LSZH, hot-pluggable and SFF-8665 are stated | Verify site material rules and the current model document |
Suitable and unsuitable routes
- Suitable for evaluation: a measured 10 m equipment route with known switch or adapter ports and accessible replacement paths.
- Validate before use: mixed device generations, breakout expectations, tight cable managers or firmware combinations not covered by confirmed support data.
- Usually unsuitable: routes that require patch-panel termination, exceed the fixed length, expose the cable to pulling stress, or lack enough bend clearance.
10 m AOC, DAC or separate optics
A fixed AOC integrates the optical engines and fiber, which reduces the number of separate components but also makes length, handling and whole-cable replacement part of the design. A passive DAC may suit a shorter supported copper path. Separate transceivers and fiber may suit structured cabling or replaceable segments. Choose from endpoint support, pathway, maintainability and test evidence rather than media type alone.
Route and procurement checklist
- Record both endpoint models, ports, firmware and required Ethernet mode.
- Measure the actual route through rack managers and trays; include service slack without tight coils.
- Check bend, pulling, connector clearance, airflow and access for replacement.
- Put the complete `MFA1A00-C010` OPN and 10 m length on the bill of materials.
- Define labels for both ends and identify the switch port, host port and route.
Link acceptance path
- Inspect connectors and the full cable jacket before installation.
- Verify insertion, link mode, negotiated rate, FEC and error counters at both endpoints.
- Run representative traffic and monitor errors, drops and stability under declared conditions.
- Recheck the link after final dressing, then save firmware, port and cable OPN evidence.
FAQ
Can the 10 m cable be shortened or field-terminated?
No. Treat an AOC as an integrated fixed-length assembly and select the correct OPN for the measured route.
Does QSFP28 mean every 100GbE port will accept it?
No. Confirm the exact switch or adapter, port mode, firmware, FEC and model support list.
Should unused length be tightly coiled in the rack?
No. Plan the route and service slack within the cable handling limits confirmed for the model.
Evidence boundary: The technology and length statements above come from the retained record. This page does not confirm price, stock, delivery, authorization, certification, warranty, current lifecycle, universal compatibility or workload gains.
Compare the 100GbE AOC and DAC catalog, use the interconnect compatibility workflow, or document the endpoint pair in the enterprise buyer guide.
