Product overview
Juniper Networks lists JNP-QSFP-100G-SR4 as a 100GBASE-SR4 QSFP28 Transceiver Module (MMF, 100m, 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 100GBASE-SR4. Tell us both switch models and we will confirm compatibility before it ships.
Quotes are itemised down to the accessories, so nothing that is needed to make the part work is left off and discovered later.

What you get ordering this from us
Ordered by part number
The order is placed against JNP-QSFP-100G-SR4, not against a description of it, so there is no room for a substitution you did not agree to.
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.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Questions buyers ask about this part
Is JNP-QSFP-100G-SR4 genuine and is the warranty intact?
Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
Will JNP-QSFP-100G-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. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

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