What connector configuration and electrical lane structure does the Q100-Q100-C use for 100G transmission?

It uses one 100G QSFP28 connector at each end. The cable carries four 25Gb/s NRZ electrical lanes over twinax copper pairs, providing an aggregate data rate of up to 100Gb/s between the two ports.

What cable lengths are available for the Q100-Q100-C passive direct attach copper cable?

From 0.5m to 5m. These fixed-length options are intended for short-distance connections between compatible 100G QSFP28 devices within a rack or between closely positioned data center equipment. ([Cisco][1])

Can the Q100-Q100-C divide one 100G QSFP28 port into four independent 25G SFP28 connections?

No. The Q100-Q100-C is a straight-through QSFP28-to-QSFP28 cable that connects two 100G ports. A QSFP28-to-4×SFP28 breakout cable with four separate branch connectors is required for four independent 25G links. ([Cisco][1])

Does the Q100-Q100-C require separate optical transceivers or fiber patch cables to complete the connection?

No. It is an integrated passive copper cable assembly with QSFP28 connectors already attached at both ends. Each connector plugs directly into a compatible 100G QSFP28 port without separate optical modules or fiber cabling.

Which types of network equipment can be connected with the Q100-Q100-C?

It connects two compatible 100G QSFP28 ports on equipment such as switches, servers, network adapters, and other data center devices. Both ports must support a straight-through 100G copper connection and recognize the installed cable assembly.

Is the Q100-Q100-C hot-pluggable when used with compatible 100G QSFP28 ports?

Yes. The Q100-Q100-C uses the hot-pluggable QSFP28 form factor, allowing it to be inserted into or removed from compatible QSFP28 ports without opening the equipment chassis.

100G QSFP28 DAC Overview

The 100G QSFP28 DAC category contains one passive direct attach copper twinax cable for short-distance 100G data center interconnections. Q100-Q100-C uses 100G QSFP28 connectors at both ends to establish a direct copper link between compatible network ports and is available in lengths from 0.5m to 5m. Its low-loss and low-crosstalk construction supports stable signal transmission, while the compact cable design enables high-density port connections and streamlined cabling between switches, servers, and other QSFP28-equipped data center devices.
