Product overview
Juniper Networks lists QSFPP-40G-LX4 as a 40GBASE-LX4 QSFP+ Transceiver Module (MMF, LC, up to 150m). Optics have to match at both ends and are frequently vendor-coded, so a module that is electrically correct can still refuse to link. Tell us both switch models and we will confirm compatibility before it ships.
Send the quantity you need and we will come back within 48 business hours with availability confirmed, not estimated.

What you get ordering this from us
Ordered by part number
The order is placed against QSFPP-40G-LX4, not against a description of it, so there is no room for a substitution you did not agree to.
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.

Questions buyers ask about this part
- Is QSFPP-40G-LX4 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 QSFPP-40G-LX4 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. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

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.
