Product overview
Part number QSFP-40G-SR4-S identifies this Cisco 40GBASE-SR4 QSFP+ Transceiver Module (MMF, 850nm, 150m, MTP/MPO). Optics have to match at both ends and are frequently vendor-coded, so a module that is electrically correct can still refuse to link. This is 40GBASE-SR4. Tell us both switch models and we will confirm compatibility before it ships.
Quote requests are answered within 48 business hours, with availability confirmed before you raise a purchase order rather than after.

What you get ordering this from us
Ordered by part number
The order is placed against QSFP-40G-SR4-S, not against a description of it, so there is no room for a substitution you did not agree to.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.

Questions buyers ask about this part
- Is QSFP-40G-SR4-S genuine and is the warranty intact?
- Yes. It ships new in Cisco packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
- Will QSFP-40G-SR4-S 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.
