General Description
HTF’HTST-1RTXx/ HTF’HTST-1RTx-1/ HTF’HTST-1RTx-5 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 HTST-1RTXx is compatible with 1000BASE-X auto-negotiation, but does not have a link indication feature (RX_LOS is internally grounded).
The HTST-1RTx-1 uses the RX_LOS pin for link indication, and 1000BASE-X auto-negotiation should be disabled on the host system.
The HTST-1RTx-5 is compatible with 1000BASE-X auto-negotiation, and have a link indication feature.
Power Supply Interface Electronic Characteristics
The HTST-1RTX has an input voltage range of 3.3 V ± 5%. The 4 V maximum voltage is not allowed for continuous operation.

Notes: Power consumption and surge current are higher than the specified values in the SFP MSA
Serial Communication Protocol
HTST-1RTX supports the 2-wire serial communication protocol outlined in the SFP MSA. It uses an Atmel AT24C02D 256 byte EEPROM with an address of A0h

FAQ
1、Question: Is it possible to send to Brazil?
Answer: Yes, of course.Our partners are all over the world
2、Question: Just making sure, I can plug an LC fiber connector into these correct?
Answer: Yep, these are LC. Make sure you are using MMF, not SMF for the -SR part number.
3、Question: Please, what is the product warranty? Thank You.
Answer: All Fiber Optic Transceivers share 1-year standard warranty.
