WS-G5487 (3rd party)

The WS-G5487 GBIC (1000BASE-ZX) 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.)

The WS-G5487 GBIC (1000BASE-ZX) must be coupled to single-mode fiber-optic cable, which is the type of cable typically used in long-haul telecommunications applications. The WS-G5487 GBIC (1000BASE-ZX) will not operate correctly when coupled to multimode fiber, and the WS-G5487 (1000BASE-ZX) is not intended to be used in application environments (e.g., building backbones or horizontal cabling) where multimode fiber is frequently used.

The WS-G5487 GBIC (1000BASE-ZX) is intended to be used as a physical medium dependent (PMD) component for Gigabit Ethernet interfaces, as found on various switch and router products. Teh WS-G5487 (1000BASE-ZX) will operate at a signaling rate of 1250 MBaud, transmitting and receiving 8B/10B encoded data.
