    (See Table 4). WS-G5486 The WS-G5486, 1000BaseLX/LH interfaces fully comply with the IEEE 802.3z 1000BaseLX 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.

  • Page 3: Safety Recommendations

    Safety Recommendations 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.

  • Page 5: Handling A Gbic

    Handling a GBIC The mode-conditioning patch cord (CAB-GELX-625 or equivalent) is required to comply Note with IEEE standards. The IEEE found that link distances could not be met with certain types of fiber-optic cable cores. The solution is to launch light from the laser at a precise offset from the center, which is accomplished by using the mode-conditioning patch cord.
