Connector Specifications

WS-G5486

The WS-G5486 GBIC (1000BASE-LX/LH) interfaces fully comply with the IEEE 802.3z 1000BASE-LX standard. However, their higher optical quality allows them to reach 10 km over single-mode fiber (SMF), versus the 5 km specified in the standard.

WS-G5487

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 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 will not operate correctly when coupled to multimode fiber, and it 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 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, you might need to insert an in-line optical attenuator in the link to avoid overloading the receiver:

Insert a 10-dB in-line optical attenuator 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.

Insert a 5-dB in-line optical attenuator 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.

GBICs use an SC-type connector to link the module to the fiber-optic cable.
