D-Link DMC-920ST – 10/100BASE-TX to 100BASE-SX/LX Bi-Directional SC Single-Mode Media Converter, 20km Fiber Distance, TX 1550nm / RX 1310nm

• The D-Link DMC-920ST is a Fast Ethernet bi-directional media converter designed to convert 10/100BASE-TX copper Ethernet to 100BASE-SX/LX single-mode fiber.

• It provides 1 × 10/100BASE-TX RJ45 port and 1 × 100BASE-SX/LX bi-directional SC fiber port.

• The converter supports single-mode fiber optic cable with SC connector and transmission distance up to 20km.

• The DMC-920ST uses TX 1550nm / RX 1310nm wavelength operation, making it suitable for single-fiber bi-directional links when paired with the opposite wavelength model.

• It supports Half-Duplex / Full-Duplex operation, Auto-MDI/MDIX, store-and-forward transmission, and full wire-speed forwarding rate.
