However, some degradation may be incurred in overall performance. 2 Measured average power coupled into single mode fiber (SMF). For50 µm or 62.5µm multimode fiber (MMF) operation, the output power is 0.5dB less and is measured after a single mode fiber offset-launch mode-conditioning patch cord as specified in IEEE 802.3z Draft 5.0.
