Passive optical fiber assemblies technical selection questions

These questions are prepared from the cited technical documentation and clearly scoped owner inputs. They are not a measured frequency ranking. Keep the applicability line with each answer; do not transfer board, cooling, crypto, protocol, cable length or firmware facts between variants.

Is MFP7E20-N010 an AOC?

Applicable canonical content subjects: 980-9I554-00N010.

No. It is a 10 m passive multimode fiber splitter with female MPO/APC connectors. Separate optical engines are required.

Public references

What breakout does one assembly provide?

Applicable canonical content subjects: 980-9I554-00N010.

It routes one four-channel optical port to two two-channel optical ports. With the documented 100G-PAM4 transceivers, that creates two 200G branches.

Which fiber grade is specified for the 10 m version?

Applicable canonical content subjects: 980-9I554-00N010.

The specification uses OM3 for lengths up to 30 m, so the N010 assembly is OM3, 50/125 µm. Its connector topology is Type-B crossover.

How many assemblies split a twin-port optic into four links?

Applicable canonical content subjects: 980-9I554-00N010.

Two, one for each optical port. The MMA4Z00-NS guidance requires both optical connections to use the same straight-versus-splitter configuration.

How should detachable optical connectors be cleaned?

Applicable canonical content subjects: 980-9I554-00N010, 980-9I58G-00N030.

Use a connector-appropriate fiber cleaning tool on both mating surfaces before connecting them. Keep protective caps when disconnected.

Is it safe to look into a connected optical port?

Applicable canonical content subjects: 980-9I554-00N010, 980-9I58G-00N030.

No. Never look directly into an energized optical port or connected fiber; its infrared light can be invisible.

Public references

What distinguishes MFP7E30-N030 from the MMF splitter?

Applicable canonical content subjects: 980-9I58G-00N030.

It is a 30 m straight single-mode 9/125 µm assembly, with female MPO12/APC connectors and Type-B crossover. It has no fan-out.

Public references

Does the family maximum change this cable’s length?

Applicable canonical content subjects: 980-9I58G-00N030.

No. The selected N030 assembly is 30 m. A longer family maximum does not change the physical length of this SKU.

Public references

What must match at the two optical ends?

Applicable canonical content subjects: 980-9I58G-00N030.

Match single-mode optical format, MPO/APC polish, channel mapping and end-to-end loss. An optical module’s OSFP or QSFP host shell does not change the required fiber interface.

Public references

Is there an exact CPO-related reference?

Applicable canonical content subjects: 980-9I58G-00N030.

Yes. NVIDIA’s Q3450 accessory table lists 980-9I58G-00N030 in its CPO topology section. This does not validate arbitrary optical modules attached to that fiber.
