What connector configuration does Q100-4S25-A provide for a 100G-to-25G breakout connection?

It provides one 100G QSFP28 connector on the main side and four 25G SFP28 connectors on the branch side, forming a 1-to-4 active optical breakout assembly.

How is the total bandwidth of Q100-4S25-A distributed across its four SFP28 branches?

The 100Gb/s aggregate bandwidth is divided into four discrete 25Gb/s channels. Each SFP28 branch carries an independent 25G connection, and the four channels connect to the single QSFP28 interface.

What cable lengths are available for Q100-4S25-A?

From 1m to 100m. Q100-4S25-A is supplied as an integrated active optical cable assembly, so customers should select the required fixed length when ordering.

Can Q100-4S25-A connect one 100G QSFP28 switch port to four separate 25G servers or network adapters?

Yes. The QSFP28 side connects to a compatible 100G port, while the four SFP28 branches connect to separate 25G devices. The 100G host port must support and be configured for 4x25G breakout operation.

Is Q100-4S25-A intended for a direct 100G QSFP28-to-QSFP28 connection?

No. Q100-4S25-A is a breakout cable rather than a straight-through 100G cable. One end uses QSFP28, while the opposite side terminates in four SFP28 connectors for four 25G links.

Can the optical ends or fiber section of Q100-4S25-A be replaced separately after installation?

No. The optical electronics, fiber cable, QSFP28 end, and four SFP28 ends are supplied as one integrated AOC assembly rather than as separate transceivers and removable fiber patch cords.

100G QSFP28 Breakout AOC Overview

The 100G QSFP28 Breakout AOC category contains the Q100-4S25-A, a 1–100m active optical breakout cable that divides one 100G QSFP28 interface into four 25G SFP28 branches. Each branch carries an independent 25G connection, distributing the full 100G main-port bandwidth across four SFP28-equipped devices. It supports direct optical interconnections between data center equipment using 100G QSFP28 ports and servers, network adapters, switches, or other devices equipped with 25G SFP28 ports.
