Description
Specifically, the Cisco GLC-SX-MMD is a 1000BASE-SX SFP transceiver module designed for short-wavelength multimode fibre (MMF) Gigabit Ethernet and 1G Fibre Channel applications. Furthermore, operating at 850nm, it provides a cost-effective, high-performance solution for campus and data centre fibre connections.
Furthermore, the GLC-SX-MMD SFP transceiver is fully compliant with the SFP Multi-Source Agreement (MSA) and IEEE 802.3z standards. Moreover, it features Digital Diagnostic Monitoring (DDM/DOM) in compliance with SFF-8472, enabling real-time monitoring of optical performance without disrupting traffic.
In addition, this 1000BASE-SX SFP module supports up to 550m on OM2 MMF and up to 1000m on OM3 MMF. Additionally, it has been tested and verified to be fully compatible with Cisco network equipment, including Ethernet switches, routers, NICs, and media converters.
Specifically, the GLC-SX-MMD module consists of a VCSEL laser, PIN photodetector, LD controller, limiting amplifier, and digital diagnostic monitor. Furthermore, it is a Class 1 laser product compliant with FDA/CDRH and IEC-60825 standards. Additionally, it operates on a single 3.3V power supply with low power dissipation and a metal enclosure for reduced EMI.
