GLC-SX-MMD Specifications and Details
Overview
The GLC-SX-MMD 1000BASE-SX SFP is made for Multimode Fiber only.
The 1000BASE-SX SFP, compatible with the IEEE 802.3z 1000BASE-SX standard, operates on legacy 50 μm multimode fiber links up to 550 m and on 62.5 μm Fiber Distributed Data Interface (FDDI)-grade multimode fibers up to 220 m. It can support up to 1km over laser-optimized 50 μm multimode fiber cable. 850-nm wavelength, extended operating temperature range and DOM support, dual LC/PC connector.
Features
The Cisco GLC-SX-MMD is a Gigabit Ethernet short-range, multimode SFP (Small Form-Factor Pluggable) module. Here are the key features of the Cisco GLC-SX-MMD SFP Module:
- Gigabit Ethernet Connectivity:
- Provides Gigabit Ethernet connectivity, supporting data rates of up to 1 Gbps.
- Short-Range Transmission:
- Designed for short-range transmissions over multimode fiber, making it suitable for connections within data centers and enterprise networks.
- Multimode Fiber Compatibility:
- Specifically designed for use with multimode fiber optic cables, supporting distances of up to 550 meters (depending on the quality of the fiber).
- LC Duplex Connector:
- Equipped with an LC duplex connector, which is a standard connector for fiber optic cables.
- MMF Support:
- Compatible with multimode fiber (MMF) types, including 62.5/125 µm and 50/125 µm.
- 850 nm Wavelength:
- Operates at a wavelength of 850 nm, which is typical for short-range multimode fiber applications.
- Hot-Pluggable:
- Hot-pluggable design allows for the module to be inserted or removed without disrupting the operation of the network.
- Digital Optical Monitoring (DOM):
- Supports Digital Optical Monitoring (DOM), allowing for real-time monitoring of various parameters such as optical power levels and temperature.
- Cisco Quality and Compatibility:
- Manufactured by Cisco, ensuring high quality and compatibility with Cisco networking equipment.
