ZYXEL SFP (Mini-GBIC) Transceiver Module - 1Gbps 1000BASE-SX/LX/EX for Gigabit Ethernet Network Switches & Routers - Perfect for Data Centers, Enterprise Networks, and Telecom Applications

Reliable Transceiver Modules for Different Connectivity Demands | Hot-pluggable with maximum flexibility Independent transceiver design provides the highest network maintenance flexibility. Transceivers can be freely added when required, and infrastructure upgrades or transceiver repairs can be done easily by just replacing the transceiver instead of the whole device. No extra cabling cost to upgrade the fiber plant Traditional fiber optic networking requires two strands of fiber for sending and receiving signals to accomplish communications. The bi-directional, dual-wavelength transceivers can establish communications over just one strand of fiber. Transmission capacity can be expanded immediately without additional cost laying new fiber.
