General Description
The optical output can be disabled by a TTL logic high-level input of Tx Disable, and the system also can disable the module via I2C. Tx Fault is provided to indicate that degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver or the link status with partner. The system can also get the LOS (or Link)/Disable/Fault information via I2C register access.

FAQ
1、Question：How do SFP and XFP differ?
Answer：
XFP is a standard for the transceivers. This type of transceiver is not dependent on the protocol. Generally, it operates at optical wavelengths corresponding to 850nm, 1310nm or 1550nm. The modules belonging to the XFP are hot swappable which means that the function of replacing the computer system components can be performed without shutting down the system. The specifications of XFP were developed by the XFP Multi Source Agreement Group.
“SFP” stands for “Small Form-factor Pluggable.” It is most often used for Fast Ethernet of Gigabit Ethernet applications. They are capable of supporting speeds up to 4.25Gbps. It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. It is specified by the SFP transceiver multi-source agreement.
2、Question：Why should I trust HTF compatible transceivers?
Answer：Besides the price advantage we have compared to branded transceivers, HTF compatible transceivers also maintain the same performance and reliability. To satisfy our customers' needs of high performance, all of our transceivers are tested multiple times in mainstream original brand switches in our test center before shipped out.
3、Question：What is your minimum order?
Answer：To achieve customers' satisfaction, we accept sample order, even one piece.
4、Question：What is your lead time for sampling?
Answer：It is about 1-3 working days after payment received.
