Questions & Answers
Q
What is the Q2F20A-C 100GbE QSFP28 PSM4 2 km transceiver?
A
The Q2F20A-C is a HPE M-Series–compatible 100 Gigabit Ethernet QSFP28 PSM4 optical transceiver designed for single-mode fiber links up to 2 km.
Q
Which HPE M-Series switches support the Q2F20A-C transceiver?
A
It is fully compatible with HPE Aruba M-Series switches such as the 8400, 8320, 8325 and other QSFP28-enabled M-Series platforms.
Q
What type of fiber does the Q2F20A-C require?
A
The transceiver requires single-mode fiber (SMF) with an MPO-12 connector for PSM4 parallel optics applications.
Q
What is the maximum reach of the Q2F20A-C transceiver?
A
It supports optical transmission distances of up to 2 kilometers over single-mode fiber.
Q
Is the Q2F20A-C QSFP28 PSM4 transceiver MSA compliant?
A
Yes, the Q2F20A-C complies with the QSFP28 MSA, IEEE 802.3bm PSM4 specifications and ensures full interoperability.
Q
What data rate does the Q2F20A-C transceiver support?
A
It supports 100 Gbps line rate via four 25 Gbps electrical lanes in a compact QSFP28 form factor.
Q
Which connector type is used by the Q2F20A-C?
A
It uses a standard MPO-12 fiber connector on the optical side and a QSFP28 cage on the host side.
Q
What is the operating temperature range of the Q2F20A-C?
A
The operating range is 0 °C to 70 °C (32 °F to 158 °F), suitable for data-center environments.
Q
What is the typical power consumption of the Q2F20A-C?
A
The transceiver consumes less than 3.5 W under standard operating conditions.
Q
How do I install the Q2F20A-C transceiver?
A

What are the benefits of using PSM4 technology?
A
PSM4 delivers cost-effective, high-density 100 Gbps over single-mode fiber with low power and proven MSA interoperability.
Q
How does PSM4 differ from SR4 transceivers?
A
PSM4 uses parallel single-mode fiber for up to 2 km reach, while SR4 uses parallel multimode fiber for shorter distances (up to 100 m).
Q
Which MPO cable should I use with the Q2F20A-C?
A
Use an MPO-12 single-mode trunk cable with LC fan-out or direct MPO-to-MPO patch cables rated for 2 km SMF PSM4.
Q
Is the Q2F20A-C transceiver hot-swappable?
A
Yes, the QSFP28 PSM4 module is hot-pluggable, allowing insertion and removal without powering down the switch.
