SR (multimode 850nm) : 300m sur OM3, 400m OM4, économique. LR (singlemode 1310nm) : 10km, fibre monomode. SR pour intra-datacenter, LR pour inter-bâtiments ou campus.

SFP+ Cisco fonctionne sur switch Juniper ?

Techniquement oui, mais Juniper vérifie via Junos. Le switch peut refuser ou émettre un warning. Préférer EX-SFP-10GE-* officiel Juniper pour garantie support.

Quelle longueur d'onde pour ZR 80km ?

ZR utilise 1550nm en monomode. Nécessite parfois un amplificateur EDFA ou DCM pour compenser la dispersion sur les très longues distances.

Which 10G SFP+ Should You Choose? Brand-by-Brand Guide

10G SFP+: The World's Best-Selling Optical Module

SFP+ (Small Form-factor Pluggable Plus) is the standard transceiver for 10 Gigabit Ethernet connections. Introduced in 2006, it replaced the bulkier XFP and remains the world's best-selling module by volume in 2026. It is found in every campus switch for uplinks, every firewall for WAN/DMZ interfaces, every data center leaf switch for server connectivity, and every router for PE/CE uplinks. Choosing the right SFP+—the correct manufacturer, reach, and coding—is critical.

Cross-Brand Compatibility Rules

Each manufacturer writes a proprietary code to the module's EEPROM. The switch checks this code at boot. If the code does not match:

Cisco: the port enters an err-disabled state → use the service unsupported-transceiver command to override the restriction.
Juniper: the port does not come up → use set chassis no-verify-sfp (but this also disables the detection of faulty modules).
Fortinet: third-party modules are often accepted, but FortiCare may refuse support when a non-official SFP is installed.
Aruba: third-party modules are generally accepted, although HPE recommends its own part numbers.
Palo Alto: strict policy—PAN Support refuses tickets involving non-official SFP modules.

OPTINOC recommendation: always purchase the official SFP from your switch manufacturer. The additional cost of €50-100 per module is negligible compared with the risk of TAC support being refused during a critical incident.
