Both models (Figure133) conform to the IEEE 802.3z 1000BASE-LX standard
and use longwave 1300 nm fiber optic connectors to connect devices over single
mode (3 kilometer) or multimode (550 mete r s) fiber optic cable.

Table 6 8 describes the 1000BASE-LX MDA components and LEDs.
Note: The optical performance of this transceiver cannot be guaranteed
when connected to a multimode fiber plan t without the use of the special
offset SMF/MMF mode conditioning patch cord (see 1000BASE-LX
multimode applications on page367).
