Passive Optical Cables (POCs) technical selection Q&A

These questions were prepared for technical evaluation from cited documentation. They are not a measured list of frequently asked customer questions. The applicability line belongs to each answer; do not transfer a statement between order-code, firmware, cooling, length, form-factor or crypto variants.

The products listed below are the applicable catalog references. Answers use owner-confirmed manufacturer-origin product data, scoped public documentation, or explicitly stated engineering guidance. Genuine conflicting values are qualified individually.

What is MFP7E70-X005?

Applicable catalog candidates: 980-9IB30-00X005.

It is an owner-confirmed 5 m passive fiber assembly with MMC12/APC at one end and two MPO12/APC branches. It requires separate optical engines at the link endpoints.

Does this assembly contain an optical transceiver?

Applicable catalog candidates: 980-9IB30-00X005.

The manufacturer-origin description identifies it as passive fiber. Select the optical transceivers or integrated optical endpoints separately; do not assign it an AOC power or data-rate specification.

Does MMC12/APC determine whether the fiber is single-mode?

Applicable catalog candidates: 980-9IB30-00X005.

No. US Conec documents MMC technology for both single-mode and multimode fibers. The supplied record’s MMF-versus-SM wording must be reconciled before choosing the optical endpoint pair.

Public references: US Conec MMC Connectors.

What should be checked before connecting the two MPO branches?

Applicable catalog candidates: 980-9IB30-00X005.

Verify fiber type, connector gender/polish and the lane/polarity map from each transmitter to the intended receiver. An MMC16 switch-interface reference does not qualify an MMC12 assembly.

Can copper assemblies connect to Q3450 CPO data ports?

Applicable catalog candidates: 980-9IB30-00X005.

No. NVIDIA identifies these as fiber interfaces. A compatible fiber path and optical endpoints are required.

Why can a cable have two minimum bend radii?

Applicable catalog candidates: 980-9IB30-00X005.

The connector exit generally needs a larger bend radius than the cable body. Follow the exact assembly drawing and leave adequate space behind the rack door.
