AO Corporation WS-G5487=C GBIC 1000Mbit/s Single-mode network transceiver module

Cisco Compliant 1000Base-ZX GBIC, 1 x 1000Base-ZX LAN, GBIC This exclusive Industry-leading "Tier 1" technology Gigabit Interface Converter (GBIC) is 100% Cisco compliant and is approved for Federal, State, Local government and Fortune 500 corporate network applications. The WS-G5487 GBIC is a hot-swappable input/output device that plugs into a Gigabit Ethernet port or slot, linking the port with the network. Advantage Optics' GBICs can be interchanged on a wide variety of Cisco products and can be intermixed in combinations of 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, 1000BASE-ZX, or 1000BASE-CWDM interfaces on a port-by-port basis. The WS-G5487 operates on ordinary single mode fiber optic link spans of up to 70 km in length. Link spans of up to 100 km are possible using premium single mode fiber or dispersion shifted single mode fiber (premium single mode fiber has a lower attenuation per unit length than ordinary single mode fiber; dispersion shifted single mode fiber has both lower attenuation per unit length, and less dispersion).
