An SFP Procurement Checklist for Infrastructure Buyers
Optical Engineering Guide
A step-by-step checklist to avoid costly wrong transceiver orders: host device, port speed, connector type, and reach.
Technical Attribute Comparison Matrix
Step 1: Host PortCheck exact switch/router modelSFP (1G) vs SFP+ (10G) vs SFP28 (25G) vs QSFP28 (100G)
Step 2: Media TypeFiber vs CopperSingle-mode OS2 vs Multimode OM4 vs RJ-45 Cat6A
Step 3: DistancePhysical route measurementShort reach (SR/SX) vs Long reach (LR/LX) vs Extended (ER/ZR)
Step 4: ConnectorPhysical termination styleLC Duplex vs MPO/MTP-12 vs BiDi Simplex LC
Pre-Procurement Checklist
Check if BiDi (Bi-Directional Simplex) is required when only 1 fiber strand is available.
Note operating temperature requirement: Commercial (0°C to 70°C) vs Industrial (-40°C to 85°C) for outdoor cabinets.
Confirm software firmware release of the host switch.
