Prices in Euro incl. Taxes
The WS-G5487 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 will not operate correctly when coupled to multi-mode fiber, and it is not intended to be used in application environments (e.g. building backbones, horizontal cabling) where multi-mode fiber is frequently used. The WS-G5487 is intended to be used as a Physical Medium Dependent (PMD) component for Gigabit Ethernet interfaces, as found on various switch and router products. It will operate at a signaling rate of 1250 MBaud, transmitting and receiving 8B/10B-encoded data. When shorter distances of single mode fiber are used, it may be necessary to insert an in-line optical attenuator in the link, to avoid overloading the receiver. A 10 dB in-line optical attenuator should be inserted between the fiber optic cable plant and the receiving port on the WS-G5487 GBIC at each end of the link whenever the fiber optic cable span is less than 25 km. A 5 dB in-line optical attenuator should be inserted between the fiber optic cable plant and the receiving port on the WS-G5487 GBIC at each end of the link whenever the fiber optic cable span is equal to or greater than 25 km, and less than 50 km.
