Description
SFP-10G-T Copper Small Form Pluggable (SFP) transceivers are based
on the SFP Multi Source Agreement (MSA) . They are compatible with
the 10Gbase-T / 5Gbase-T / 2.5Gbase-T / 1000base-T standards as
specified in IEEE Std 802.3 . SFP-10G-T uses the SFP's RX_LOS(must
be pulled up on host) pin for link indication. If pull up or open
SFP's TX_DISABLE pin, PHY IC be reset.

Notes:
1. Circuit ground is connected to chassis ground
2. PHY disabled on TDIS > 2.0V or open, enabled on TDIS <
0.8V
3. Should be pulled up with 4.7k - 10k Ohms on host board to a
voltage between 2.0 V and 3.6 V. MOD_DEF(0) pulls line low to
indicate module is plugged in.
+3.3V Volt Electrical Power Interface
The SFP-10G-T has an input voltage range of 3.3 V +/- 5%. The 4V
maximum voltage is not allowed for continuous operation.

Low-Speed Signals
MOD_DEF(1) (SCL) and MOD_DEF(2) (SDA), are open drain CMOS signals
(see section VII, "Serial Communication Protocol"). Both MOD_DEF(1)
and MOD_DEF(2) must be pulled up to host_Vcc.
