Fiber type and distance set it apart from its siblings, since the GLC-SX-MMD works on multimode fiber only, while the GLC-EX-SMD stretches single-mode reach to 40 km and the GLC-ZX-SMD to roughly 70 km. This transceiver is the one that handles both fiber types, reaching 10 km over standard single-mode fiber and 550 m over multimode fiber with either 62.5 or 50 micron cores. On multimode links the transmitter must be coupled through a mode-conditioning patch cable, which the IEEE specification requires regardless of span length. The link budget allows 6 dB of channel insertion loss over single-mode fiber and 2.4 dB over multimode. Digital optical monitoring (DOM) support is built in, and the module is compatible with the IEEE 802.3z 1000BASE-LX standard. It is hot-swappable, which maximizes uptime and simplifies serviceability. It also meets Class I laser safety requirements. The module is meant for Gigabit SFP ports on Catalyst, Nexus, ASR and Industrial Ethernet platforms, among many others.\u003c\/p\u003e","brand":"Cisco","offers":[{"title":"Default Title","offer_id":67716026695853,"sku":"GLC-LH-SMD-REF","price":95.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0640\/7667\/7293\/files\/GLC-LH-SMD.jpg?v=1768421822","url":"https:\/\/netmode.com\/products\/cisco-glc-lh-smd-1000base-lx-lh-10km-sfp-transceiver-refurbished","provider":"Netmode","version":"1.0","type":"link"}
