The Cisco 30-0759-01 1000BASE-SX Short Wave GBIC is a Gigabit Ethernet optical transceiver module designed for high-speed data transmission over multimode fiber networks. This module uses the GBIC (Gigabit Interface Converter) form factor and supports the 1000BASE-SX standard defined by IEEE 802.3z, enabling reliable Gigabit Ethernet connectivity in enterprise networks, campus environments, and data center infrastructures.Operating at a wavelength of 850 nm, the transceiver is optimized for short-range optical communication over multimode fiber (MMF). It supports data transmission at 1 Gbps and can achieve distances of up to 550 meters depending on the type and quality of the multimode fiber used. The module features a duplex SC optical connector, providing a secure and widely compatible interface for fiber optic cabling.
The 1000BASE-SX GBIC module is designed for use in compatible Cisco switches, routers, and networking equipment that support the GBIC interface. It supports hot-swappable installation, allowing network administrators to insert or remove the module without shutting down the host device, which simplifies maintenance and network upgrades. With stable optical performance and dependable signal integrity, the Cisco 30-0759-01 module is a reliable solution for implementing Gigabit Ethernet fiber connections within short-distance network segments.
