Questions & Answers
Q
What is the QSFP-4SFP25G-CU3M cable?
A
The QSFP-4SFP25G-CU3M is a 3 meter passive copper splitter cable that converts one 100GBase QSFP port into four independent 25 GBase SFP28 ports for high-density, low-latency connectivity.
Q
Which data rates does this cable support?
A
This splitter cable supports 100 Gbps on the QSFP28 end and 25 Gbps on each of the four SFP28 ends, enabling full line-rate performance per lane.
Q
Is the QSFP-4SFP25G-CU3M cable passive or active?
A
The QSFP-4SFP25G-CU3M is a passive copper cable that requires no external power or electronics, ensuring simplified deployment and minimal power draw.
Q
How long is the cable and how does length affect performance?
A
The cable is 3 meters long and, as a passive assembly, it guarantees reliable signal integrity at full speed within that length without active signal conditioning.
Q
Which switch and router platforms is it compatible with?
A
This cable is compatible with most major vendors’ QSFP28 ports that support breakout mode, including Cisco, Arista, Juniper, Mellanox and Dell, when used with appropriate firmware.
Q
Can I split a single 100G port into four separate 25G connections?
A
Yes. The QSFP-4SFP25G-CU3M cable breaks out one 100 GbE QSFP port into four independent 25 GbE links, each operating and negotiating separately.
Q
What are the primary use cases for this splitter cable?
A
Ideal for data center spine-leaf architectures, top-of-rack switches, storage arrays and virtualized network functions that require cost-effective 25 GbE aggregation.
Q
How does the cable affect latency?
A
As a passive copper assembly, the QSFP-4SFP25G-CU3M introduces negligible latency (typically under 1 ns), preserving low-latency performance for high-frequency trading and HPC applications.
Q
What is the power consumption of this cable?
A
Being passive, it consumes no additional power beyond the host ports’ nominal transceiver power budget, ensuring energy-efficient operation.
Q
How do I install the QSFP-4SFP25G-CU3M cable?
A
Simply insert the QSFP28 connector into your 100 GbE port and plug each SFP28 connector into the 25 GbE ports; no configuration or external power is required.
Q
What temperature range does this cable support?
A
The cable is rated for an operating temperature of 0 °C to 70 °C (32 °F to 158 °F), making it suitable for typical data center environments.
Q
Is the cable backward-compatible with 10 Gbps or 40 Gbps QSFP+ ports?
A
No. The QSFP-4SFP25G-CU3M is designed specifically for QSFP28 100 GbE ports and requires host support for 4×25 GbE breakout; it is not compatible with QSFP+ 40 GbE.
Q
Which standards and protocols does it comply with?
A
It meets IEEE 802.3bj, 802.3by and InfiniBand EDR specifications for 100 Gbps and 25 Gbps copper interconnects, ensuring interoperability and compliance.
Q
What warranty and support are offered?
A
The cable is backed by a limited lifetime warranty and includes technical support for installation guidance and troubleshooting.
Q
What connector types are used on each end?
A
The QSFP-4SFP25G-CU3M features a QSFP28 (4×25 GbE) plug on one end and four SFP28 plugs on the other end, all gold-plated for reliable electrical contact.
Q
How does this cable deliver cost savings?
A
By eliminating the need for active optics and separate transceivers, the passive copper design reduces capital and operational expenses while simplifying inventory management.
