QSFP28 100G Optical Switch
A 100G switch is chosen on its port configuration, not on its total throughput: how many servers to connect, at what speed, and how many uplinks to reach the core. Our L3 managed chassis cover access as well as spine, with MLAG, EVPN-VXLAN and RoCEv2.

Leaf & spine: which switch goes where?
A modern fabric has two roles only — and they do not call for the same chassis.
The leaf (access)
This is where the servers plug in: plenty of 10G or 25G ports, and a few 100G ports going up to the spine. A 48 × 25G + 8 × 100G is the most common configuration today.
The spine (core)
It sees no server at all: only 100G links to the leafs. Hence an all-QSFP28 chassis such as the 32 × 100G, with front-to-back airflow suited to hot and cold aisles.
MLAG and stacking
Two leafs in MLAG present a single aggregated link to the server while remaining two separate devices: a failure or an upgrade does not cut the service.
EVPN-VXLAN
The overlay that lets you stretch a VLAN between racks without stretching the broadcast domain — the basis of an IP fabric that scales.
Comparison of port configurations
The line that matters is the access ports: that is what sets how many servers you can connect.
| Ref | Access ports | QSFP28 uplinks | Role | Worth noting |
|---|---|---|---|---|
| 29013 | 24 × 10G SFP+ | 2 × 40/100G | Leaf | The most compact of the range |
| 27100 | 48 × 10G SFP+ | 8 × 100G | Leaf | Trident 3, 1.28 Tbps, dual AC power supply |
| 27101 | 48 × 1/10/25G SFP28 | 8 × 40/100G | Leaf | Trident 3-X7, 2 Tbps |
| 28824 | 48 × 10G RJ45 | 8 × 100G | Copper leaf | The only one connecting servers over copper |
| 28902 | 48 × 10/25G SFP28 | 8 × 40/100G | High-density leaf | Apollo cloud management |
| 27104 | — | 32 × 100G | Spine | Front-to-back airflow, flexible 10/25/40/50/100G |
The ports are empty: remember the modules
A switch ships without optics. Every port you use needs a module — or an AOC/DAC cable — and that budget line often exceeds the chassis itself.
100G uplinks
QSFP28 ports: 100G SR4 module on MPO/MTP for within the rack, LR4 on duplex LC for long reaches, or a DAC cable between two neighbouring racks.
10G and 25G access
SFP+ and SFP28 ports: 10G or 25G modules depending on the server's network card. The two formats are not interchangeable.
Coding compatibility
Our modules are coded for the brand of the switch and factory-tested before shipping — the port does not reject them at boot.
Configurator
The modules page carries a configurator that starts from speed and reach and ends on the right reference.
