  • Hot-pluggable module simplifies network upgrades without downtime

4-Port 25 Gigabit SFP28 Module for EX4400

The Juniper EX4400-EM-4Y is a four-port SFP28 expansion module designed for the EX4400 line of Ethernet switches. It adds 25 Gigabit Ethernet connectivity over optical fibre for data-centre and campus networks. Network engineers expanding port density on compatible Juniper switches are the intended users.

Four SFP28 ports running at 25 Gigabit Ethernet

The decisive specification is the four SFP28 interfaces operating at 25 Gigabit Ethernet over optical fibre. This module only works in Juniper EX4400 switches, so buyers with other switch families cannot use it. Each port accepts a separate SFP28 transceiver for the required reach and fibre type.

No transceivers or cables are included

The module ships without SFP28 transceivers or fibre patch cords, so those must be sourced separately to match the link distance and fibre type. Installing the module itself requires no extra tools beyond what is used for the host switch. Buyers needing copper connectivity or longer-reach optics must select appropriate SFP28 modules on their own.

Questions about this item

What does 25 Gigabit Ethernet on each SFP28 port mean for actual throughput?

Each port runs at 25 Gbps line-rate over optical fiber, so a single link moves up to 25 Gbps of user traffic.

Which SFP28 interface standard is used and what distance does it support?

The module provides four SFP28 cages compliant with the 25GBASE optical specifications; reach depends on the transceiver optics you install.

Will this module fit in my EX4400 switch without extra brackets?

Yes, it is designed as a native expansion module for the EX4400 line and slides directly into the switch's module slot.
