According to the physical standard, Cisco SFP optical module can be divided into 1000BASE-T, 1000BASE-SX, 1000BASE-LX / LH, 1000BASE-EX, 1000BASE-ZX, 1000BASE-BX10-D / U optical module. The Cisco GLC-LH-SM optical module is a 1000BASE-LX / LH optical module, which will be covered in detail in this article.Cisco GLC-LH-SM SFP optical module overviewThe Cisco GLC-LH-SM SFP optical module is a very popular hot-swappable module that utilizes a duplex LC interface that is the smallest Gigabit Ethernet optical module for high-density fiber optic applications. This optical module conforms to the SFP MSA protocol and can be used in both single-mode fiber applications and multimode fiber applications. The Cisco GLC-LH-SM SFP optical module is composed of 1310nm FP laser emitters, PIN photodetectors, transimpedance amplifiers (TIA), microcontrollers (MCUs) and other components, in line with IEEE 802.3z 1000BASE-LX standard, the farthest supporting distance up to10 km transmission. In order ..
