Authentic SFP, SFP+, SFP28, QSFP+, QSFP28 and QSFP-DD. Cisco, Juniper, Fortinet, HPE Aruba and Palo Alto Networks.

1,133 modules available
OPTINOC offers over 600 references of authentic vendor SFP, SFP+, SFP28, QSFP+, QSFP28 and QSFP-DD modules. All our optical modules and DAC/AOC cables are vendor-warranted (OEM equipment) products, guaranteed by manufacturers Cisco, Juniper, Fortinet, HPE Aruba and Palo Alto Networks.
Vendor-warranted SFP modules guarantee full compatibility with your network equipment. Unlike third-party compatible modules, they display no alerts on Cisco IOS, Junos, FortiOS or PAN-OS, and preserve your vendor warranty and TAC, JTAC or FortiCare support. For critical infrastructures (data center, telecom operator, banking sector), this is the only reliable option.
Our catalog covers every speed on the market: SFP 1G (GLC-SX-MMD, GLC-LH-SMD, GLC-T), SFP+ 10G (SFP-10G-SR, SFP-10G-LR, SFP-10G-ER), SFP28 25G, QSFP+ 40G (QSFP-40G-SR4, QSFP-40G-LR4), QSFP28 100G (QSFP-100G-SR4-S, QSFP-100G-LR4-S) and QSFP-DD 400G (QDD-400G-DR4-S, QDD-400G-FR4-S). All fiber types are supported: OM3/OM4 multimode, OS2 singlemode, plus RJ45 copper links.
Every reference in our catalog comes with its official vendor compatibility list. We systematically check compatibility matrices (Cisco TMG Matrix, Juniper HCT, Fortinet Compatibility Matrix) to guarantee optimal operation on your Catalyst, Nexus, EX, QFX, MX, ISR, ASR, FortiGate, FortiSwitch, Aruba CX, ProCurve, PA-Series and more.
OPTINOC ships in 24 to 72 hours across Europe for in-stock modules. For backordered references, expect 5 to 10 business days. Our sales team responds to quote requests within 2 business hours for standard projects, and offers preferred terms for bulk orders (data centers, operators, integrators).
A vendor-warranted SFP module is manufactured and certified by the equipment vendor (Cisco, Juniper, Fortinet, HPE, Palo Alto). A third-party compatible module attempts to mimic the specifications but may show alerts (Unsupported Transceiver), void the vendor warranty and technical support, or cause stability issues. OPTINOC only sells authentic OEM gear.
The Catalyst 9300 supports SFP+ 10G (SFP-10G-SR, SFP-10G-LR, SFP-10G-ER, SFP-10G-T), SFP 1G (GLC-SX-MMD, GLC-LH-SMD, GLC-T), QSFP+ 40G and QSFP28 100G via optional network modules. Contact OPTINOC with your exact reference for validation.
Yes, SFP28 25G ports are backward-compatible with SFP+ 10G modules which will then operate at 10 Gbps. This allows a gradual migration from 10G to 25G in your infrastructure. The reverse is not true: an SFP28 module will not work in an SFP+ port.
SFP+ 10G modules come in several reaches: SR (Short Reach) up to 300m on OM3 fiber / 400m on OM4, LR (Long Reach) up to 10km on singlemode, ER (Extended Reach) up to 40km, and ZR (Zero Reach) up to 80km. BiDi versions use a single fiber instead of two.
Some HPE Aruba modules (J9150D, J9151E) are backward-compatible with the most recent ProCurves, but not all. References J4858/J4859 are the legacy 1G modules compatible with most ProCurves. Contact OPTINOC to verify your exact model.
Prices vary by brand and speed. SFP 1G modules: €50-200. SFP+ 10G: €150-800. QSFP+ 40G: €400-1500. QSFP28 100G: €800-3000. QSFP-DD 400G: €2000-6000. Long-distance and CWDM/DWDM modules are more expensive. Request an OPTINOC quote for net prices.
