Necessary number of fiber strands and cable recommendation for LANCOM Multimode SFP modules:
| LANCOM SFP module | Module type | Singlemode / Multimode | Max. transfer rate | Max. range | Connector type | Necessary strand number | Recommended cable type | Notes |
|---|---|---|---|---|---|---|---|---|
| LANCOM SFP-SX-LC1 | 1000Base-SX | Multimode | 1 Gbit/Sec. | 550 m | LC | 2 strands | as of OM1 | |
| LANCOM SFP-SX2-LC1 | 1000Base-SX | Multimode | 1 Gbit/Sec. | 2000 m | LC | 2 strands | as of OM2 | 2 km only possible with mode conditioning cable, otherwise max. 1 km. |
| LANCOM SFP-LX-LC1 | 1000Base-LX | Singlemode | 1 Gbit/Sec. | 10 km | LC | 2 strands | OS1 / OS2 depending on the scenario | |
| LANCOM FP-BiDi1550-SC1 | 1000Base-BX | Singlemode | 1 Gbit/Sec | 20 km | SC/UPC | 1 strand | OS1 / OS2 depending on the scenario | Bidirectional module with 1310 and 1550 nm wavelength. |
| LANCOM SFP-SX-LC10 | 10GBase-SR/SW | Multimode | 10 Gbit/Sec. | 300 m | LC | 2 strands | as of OM3 | |
| LANCOM SFP-LX-LC10 | 10GBase-LR/LW | Singlemode | 10 Gbit/Sec. | 10 km | LC | 2 strands | OS1 / OS2 depending on the scenario | |
| LANCOM SFP-LR40-LC10 | 10GBase-ER | Singlemode | 10 Gbit/Sec. | 40 km | LC | 2 strands | OS2 | |
| LANCOM SFP-SR-LC25 | 25GBase-SR/SW | Multimode | 25 Gbit/Sec. | 300 m | LC | 2 strands | OM5 | |
| LANCOM SFP-LR-LC25 | 25GBase-LR/LW | Singlemode | 25 Gbit/Sec. | 10 km | LC | 2 strands | OS1 / OS2 depending on the scenario | |
| LANCOM SFP-SR-MPO40 | 40GBase-SR/SW | Multimode | 40 Gbit/Sec. | 300 m | MPO | 8 strands | OM5 | The middle 8 of 12 fiber strands are used. It is also possible to use a cable with 12 or 16 fiber strands. In this case the remaining 4 or 8 fiber strands would lie idle. |
| LANCOM SFP-LR-LC40 | 40GBase-LR/LW | Singlemode | 40 Gbit/Sec. | 10 km | LC | 2 strands | OS1 / OS2 depending on the scenario |
