Comparison Between Cisco GLC-SX-MMD And GLC-SX-MM SFP
As a worldwide leader in IT and networking, Cisco SFPs have long enjoyed a good reputation in telecom market. With high flexibility, enhanced reliability and high compatibility, Cisco SFPs have been warmly welcomed by many Gigabit Ethernet users. At present, 1000BASE-T SFP for copper networks already could not meet the requirement of people’s calling for a new transceiver for a longer transmission distance. Under this situation, Cisco 1000BASE-SX SFP transceivers were developed, which can support up to 1 km over optimized 50 μm multimode fiber cable. Cisco GLC-SX-MM and Cisco GLC-SX-MMD are two different common types of Cisco 1000BASE-SX SFPs. They seem very similar in specification, but actually they are two different SFPs. So what are similarities and differences between Cisco GLC-SX-MM and Cisco GLC-SX-MMD? The detailed information will be fully covered in the following text. Cisco GLC-SX-MM SFP Cisco GLC-SX-MM SFP 1000BASE-SX SFP is fully covered in IEEE 802.3z. It operates ...
