Product Overview
Cisco GLC-SX-MMD is a Small Form-Factor Pluggable (SFP) transceiver that is high-performance and hot-swappable to provide dependable Gigabit Ethernet (1GbE) connectivity on multimode fiber (MMF). This module is suitable for enterprise networks, data centers, as well as environments of service providers and allows transmission of short-distance, high-speed data streams, with low latency and signal integrity. It is a perfect fit for the Cisco networking devices and this is what makes it a perfect fit when expanding the network, upgrading, or even replacing the existing SFP modules.
Key Features and Benefits
-

Product Information
The Cisco GLC-SX-MMD SFP transceiver is designed to have short-range Gigabit Ethernet connectivity over multimode fiber. It has a hot-swappable feature so that it can be installed or changed easily without shutting down devices; due to this feature, it has reduced operational interruptions. Real-time Digital Diagnostics Monitoring (DDM) makes it possible to ensure active control over optical power, temperature, and voltage to maintain network performance and reliability.
The GLC-SX-MMD supports link lengths of up to 550 meters on OM2 fiber, so it is ideal in data centers, campus networks, and enterprise networks that need high-speed and reliable connections. It is widely compatible with Cisco and can therefore be easily integrated with all switches and routers and can be a reliable and cost-effective option when upgrading or expanding a network.Product Type | SFP (mini-GBIC) |
