FAQ
What type of fiber optic cable does this SFP module require?
This SFP module requires multi-mode fiber optic cable with LC/PC connectors. Multi-mode fiber is typically used for shorter distance connections up to 550 meters, depending on the fiber grade. The module supports duplex LC connections, meaning you'll need two fibers (transmit and receive) in an LC duplex cable or two separate LC patch cords.
What is the maximum data transfer rate of this SFP module?
The ECI Networks GLC-SX-MMD-ECI SFP module supports data transfer rates up to 1 Gbps (Gigabit per second) using the 1000Base-SX standard. This provides full Gigabit Ethernet performance for network backbone connections, server links, and inter-switch trunks over fiber optic cabling.
Is this SFP module hot-swappable?
Yes, this SFP module features a hot-swappable design that allows installation or removal while the networking equipment remains powered on. This enables maintenance, upgrades, and reconfiguration without disrupting network operations or requiring scheduled downtime for the connected switch or router.
What Cisco equipment is this SFP module compatible with?
This MSA-compliant SFP module is compatible with numerous Cisco Catalyst series switches including the 2960, 3550, 3560, 3750, 4500, 4900, and 6500 series. It also works with Cisco ME series, Nexus 7000 series, and various router platforms including the 7300, 7600, and uBR series. Always verify compatibility with your specific equipment model before deployment.
What is the difference between 1000Base-SX and other Gigabit Ethernet standards?
1000Base-SX is a Gigabit Ethernet standard specifically designed for short-wavelength transmission over multi-mode fiber optic cable, typically supporting distances up to 550 meters. This differs from 1000Base-LX (long-wavelength for single-mode fiber, longer distances) and 1000Base-T (copper Ethernet over CAT5e/6 cable). The SX variant is commonly used for cost-effective fiber connections within buildings or campuses.
Does this SFP module support DOM/DDM monitoring?
The product specifications do not indicate Digital Optical Monitoring (DOM) or Digital Diagnostic Monitoring (DDM) capabilities. This module provides basic 1000Base-SX functionality without advanced monitoring features. For applications requiring temperature, voltage, or optical power monitoring, verify whether your specific equipment supports these features independently of the transceiver.
