1000 BASE-T铜质单模SFP模块GPSFP-GE-T
Product Details
Product Advantage
Product Parameter :
GPSFP-GE-T Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA). They are compatible with the Gigabit Ethernet standards as specified in IEEE STD 802.3. The 1000 BASE-T physical layer IC (PHY) can be accessed via I2C, allowing access to all PHY settings and features.
The GPSFP-GE-T uses the RX_LOS pin for link indication, and 1000BASE-X auto-negotiation should be disabled on the host system.

Notes:
1. Circuit ground is connected to chassis ground.
2. 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. LVTTL compatible with a maximum voltage of 2.5V.
V. Power Supply Interface Electronic Characteristics
The GPSFP-GE-T has an input voltage range of 3.3 V ± 5%. The 4 V maximum voltage is not allowed for continuous operation.
