D-Link DMC-920SR – 10/100BASE-TX to 100BASE-SX/LX Bi-Directional SC Single-Mode Media Converter, 20km Fiber Distance, TX 1310nm / RX 1550nm
Overview:
• The D-Link DMC-920SR 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-920SR uses TX 1310nm / RX 1550nm 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.

Connect Gates Recommendation:
• Connect Gates recommends the D-Link DMC-920SR for projects requiring single-fiber Fast Ethernet conversion up to 20km.
• It is suitable for CCTV networks, office networks, factories, warehouses, and building-to-building connections where fiber cores are limited.
• The TX 1310nm / RX 1550nm wavelength should be matched with the opposite-end compatible model, such as DMC-920ST, to ensure correct bi-directional communication.
• Before installation, Connect Gates recommends checking single-mode fiber availability, SC connector type, required distance, wavelength pairing, RJ45 port speed, power availability, and whether standalone or DMC-1014 chassis mounting is required.
