Patch Cords
- SX to SX optical module use MM multimode fiber, MM normally use OM1 (62.5/125um) or OM2 (50/125um) patch cord.
- LX to LX optical module use SM singlemode fiber, SM normally use OS2 (9/125um) fiber optical patch cord.
- SR to SR optical module use MM multimode fiber, MM normally use OM3 (50/125um) patch cord.
- LR to LR optical module use SM singlemode fiber, SM normally use OS2 (9/125um) fiber optical patch cord.
- QSFP SR4 TO QSFP SR4 use MM multimode, use MPO OM3 (50/125um) patch cord.
