HPE Juniper Networking EX4400-EM-4S SFP+ switch module
Four-port SFP+ module adds 10 Gigabit Ethernet optical uplinks to Juniper EX4400 switches
- Adds four 10 Gigabit Ethernet SFP+ ports to your EX4400 switch
- Uplink or downlink at 10 Gbps over optical fiber
- Hot-swappable SFP+ module keeps the network running during changes
- Weighs only 0.20 lb for easy handling and dense deployments
- Purpose-built for Juniper EX4400 line of Ethernet switches
EX4400 SFP+ module for 10G optical links
The EX4400-EM-4S adds four SFP+ ports to compatible EX4400 switches for 10 Gigabit Ethernet over optical fiber. It is built for data-centre and campus networks that need additional high-speed uplinks or downlink connectivity. The module plugs directly into the switch expansion slot without extra cabling.
Passive optics keep thermals and noise low
As a transceiver carrier the module draws minimal power and adds no active cooling, so it does not increase chassis fan speed or acoustic output. Heat contribution stays negligible during normal operation across the supported EX4400 line. Power budget impact is small compared with the switch base system.
Four SFP+ ports set the density limit
Only four 10G ports are available per module, so each slot provides a fixed uplink count. Buyers who need more than four 10G connections per chassis must populate additional slots or choose a different platform. The 0.20 lb weight has no bearing on port capacity.

Questions about this item
How do I install the EX4400-EM-4S module into an EX4400 switch without damaging the SFP+ cages?
Power off the switch, slide the module into an empty expansion slot until the latch clicks, then insert compatible SFP+ transceivers straight into the four cages to avoid bent pins.
What maintenance will the EX4400-EM-4S need after deployment?
Periodically inspect the four SFP+ ports for dust, clean connectors with approved fibre wipes, and replace any transceiver that shows excessive errors or physical damage.
What throughput limit appears first when all four ports run 10 Gigabit Ethernet continuously?
The module provides four 10 Gigabit Ethernet SFP+ ports, so aggregate bandwidth tops out at 40 Gbps before any port-level congestion occurs.
