Application.
1.RS232/RS485/RS422 receptacle fiber transmission.
2.Fiber System.
Absolute Maximum Ratings
Operating of the transceiver beyond the Absolute Conditions Listed in Table 1 will degrade or damage the product. It’s not implied that the product would function above the recommended operating environment, it’s possible to reduce the reliability and lifetime of device if Recommended Operating Environment is exceeded.
(Refer to table 2)

Note1:The optical power is launched into 62.5/125μm MMF.
Note2:With 10Mbps. If keep 0 1 level duty ratio of 45%:55%, sensitivity control as ≤- 25dBm.
EEPROM Information Functions.
The standard SFP serial ID provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer, and other information.
Additionally, SFP transceivers provide a unique enhanced digital diagnostic monitoring interface, which allows real- time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, and received optical power and transceiver supply voltage. It also defines a sophisticated system of alarm and warning flags, which alerts end - users when particular operating parameters are outside of a factory set normal range. The SFP MSA defines a 256 byte memory map in E 2PROM that is accessible over a 2- wire serial interface at the 8 bit address 1010000X (A0h).
Host Board Layout
A typical host board mechanical layout for attaching the SFP Connector and Cage System is shown in Figures 1and 2.
