A network administrator is planning a fiber link between two buildings that are 400 meters (1,312 feet) apart. The budget is limited, and the administrator wants to reuse existing fiber. The existing fiber is OM1 multimode. The switches have SFP ports. Which option is the most cost-effective way to achieve a 1 Gbps link?

Use 1000BASE-LX transceivers with a mode-conditioning patch cord on the existing OM1 fiber.

Replace the OM1 fiber with single-mode fiber and use 1000BASE-LX transceivers.

Use 1000BASE-SX transceivers on the existing OM1 fiber.

Use 100BASE-FX transceivers on the existing OM1 fiber.
