The Cisco 30-1301-02 is a multi-mode fiber (MMF) Small Form-Factor Pluggable (SFP) transceiver module designed for Gigabit Ethernet and Fibre Channel applications over short distances. This hot-swappable module operates at a wavelength of 850 nm and uses an LC duplex connector interface, providing a reliable and standardized optical link between Cisco switches, routers, and other network equipment. It is compliant with the SFP Multi-Source Agreement (MSA) standards, ensuring interoperability with a wide range of SFP-capable devices from Cisco and other vendors. The module supports data rates up to 1.25 Gbps, making it suitable for 1000BASE-SX Ethernet links and 1G/2G Fibre Channel connections within data centers, campus networks, and storage area networks (SANs).

The transceiver is engineered for performance and reliability, featuring digital diagnostics monitoring (DDM) capabilities that allow network administrators to monitor real-time parameters such as optical output power, input power, temperature, and laser bias current via the host device's interface. This aids in proactive link management and troubleshooting. Built to meet Cisco's quality standards, the 30-1301-02 is designed for high MTBF (Mean Time Between Failures) and stable operation in standard commercial temperature ranges. Its compact form factor and low power consumption make it an efficient choice for high-density network deployments where space and power are considerations.

As a fundamental component for building fiber optic network infrastructure, this SFP module provides a flexible and cost-effective solution for extending Gigabit connectivity. Its plug-and-play design simplifies installation and maintenance, while its compatibility with Cisco's extensive switching and routing portfolio ensures seamless integration into existing network environments.
