10/100/1000M Copper SFP

ASCENT’S SFP-AG-CO-02 10/100/1000 BASE-T Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA).They are compatible with the Gigabit Ethernet and 1000BASE-T standards as specified in IEEE Std 802.3 . The 10/100/1000 BASE-T physical layer IC (PHY) can be accessed via I2C, allowing access to all PHY settings and features.

•    Up to 1.25 Gb/s bi-directional data links

•    Hot-pluggable SFP footprint

•    Low power dissipation(1.05W typical)

•    Compact RJ-45 connector assembly

•    Fully metal enclosure, for lower EMI

•    RoHS compliant and lead-free

•    Single +3.3V power supply

•    10/100/1000 BASE-T operation in host systems with SERDES interface

•    1.25 Gigabit Ethernet over Cat 5 cable


+3.3V Volt Electrical Power Interface 

The SFP‑AG‑CO‑02 has an input voltage range of 3.3 V ± 5%. The 4V maximum voltage is not allowed for continuous operation.
