The GLC-ZX-SM= is one of Cisco's 1000BASE-ZX Small Form-factor Pluggable (SFP) interface converters. These hot-swappable input/output devices plug into a Gigabit Ethernet port or slot, linking the port with the network. This model operates on standard single-mode fiber-optic link spans up to 70 km long. When shorter distances of single-mode fiber are used, it might be necessary to insert an inline optical attenuator in the link to avoid overloading the receiver.
Here are some notable features of this product:
- Hot-swappable when deployed (the switch or router does not have to reboot)
- Can be intermixed in combinations of other 1000BASE SFPs on a port-by-port basis
- Supported across a variety of Cisco switches, routers, and optical transport devices

Cisco will provide five years of hardware and software service and support ("SMARTnet") for this product.
