Questions & Answers
Q
What is QSFP-40G-CSR4= and what does it do?
A
The QSFP-40G-CSR4= is a 40 Gbps QSFP transceiver module that aggregates four 10 Gbps channels using 4×10GBASE-SR optics and an MPO connector, enabling high-density, short-reach data center links up to 300 meters over OM3 fiber.
Q
What data rate and wavelength does the QSFP-40G-CSR4= support?
A
This module supports a total data rate of 40 Gbps via four 10 Gbps channels at a nominal wavelength of 850 nm, optimized for multimode fiber transmission.
Q
Which fiber types and link distances are compatible?
A
The QSFP-40G-CSR4= is compatible with OM3 and OM4 multimode fibers, supporting up to 300 meters on OM3 and up to 400 meters on OM4 when properly certified.
Q
What connector type does this transceiver use?
A
It uses a standard MPO/MTP™ 12-fiber female connector for the 4×10GBASE-SR channels, simplifying high-density fiber routing.
Q
Which network devices support the QSFP-40G-CSR4=?
A
