Opis
Transceivery SM 10GL Copper Small Form Pluggable (SFP) są oparte
na
umowie SFP Multi Source Agreement (MSA). Są kompatybilne ze
standardami 10Gbase-T / 5Gbase-T / 2.5Gbase-T / 1000base-T
określonymi
w IEEE Std 802.3. SM 10GL wykorzystuje pin RX_LOS SFP (należy podciągnąć na
hoście) do wskazywania łącza. Jeśli podciągniesz lub otworzysz pin TX_DISABLE SFP,
PHY IC zostanie zresetowany.
