Product overview
Juniper Networks lists EX-QSFP-40GE-SR4 as a 40GBASE-SR4 QSFP+ Transceiver Module (MMF, MPO). Reach, fibre type and connector have to agree along the whole path, and a patch panel in the middle counts. Send the run length and the fibre already installed and we will match it.
Tell us the switch at each end and we will confirm the coding before anything ships, not after it fails to link.

What you get ordering this from us
Ordered by part number
EX-QSFP-40GE-SR4 is what is quoted and EX-QSFP-40GE-SR4 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
Coded for both ends
Tell us the switch at each end and we confirm the vendor coding before dispatch rather than after a link fails to come up.
Questions buyers ask about this part
- Is EX-QSFP-40GE-SR4 genuine and is the warranty intact?
- Yes — new and sealed, with the Juniper Networks warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will EX-QSFP-40GE-SR4 work in my server?
- Tell us the switch at both ends of the link. Optics are frequently vendor-coded, so a module that is electrically correct can still refuse to come up; we confirm the coding for both ends before it ships.
- Do you accept purchase orders and quote at volume?
- Yes — POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

Specifying a system, not just the part?
Optics and cabling are part of the fabric spec on a cluster build — both ends and the switch have to agree.
