Function de scription:
The SFP (Small Form Factor Pluggable ) transceivers is compliant with SFP MSA (Multi-Source Agreement ) and SFF-8472. All modules satisfy Class I Laser Safety requirements in accordance with the international IEC-825 standards.The transmit and receive functions are contained in a SFP 20 pin package with a Duplex LC or SC connector interface.
The transmitter incorporates a highly reliable 1310 nm or 1550 nm Laser (FP laser for narrow, Intermediate distance and DFB laser for long distance)
and a driver circuit which converts data to light with APC function. The output power can be disable via he single TX_Disable pin. Logic LVTTL HIGH
level disables the transmitter. The receiver incorporates an efficient InGaAs/InP PIN or APD photodiode receiver converting the light signal into an
electrical current which is amplified and regenerated into data. The transimpedance amplifier IC has internal AGC for wide dynamic range.
The postamplifier is AC coupled to preamplifier through a capacitor and a low pass filter. It can be enough to pass the signal from 100Mb/s to
2.5Gb/s without significant sensitivity. A Signal Detect status output flag is also provided.
The transceiver operates from a single +3.3V power supply over an operating temperature range of 0 to +70C. The transceiver uses the SFP 20-pin connector to allow hot plug capability. Detailed product information in EEPROM and digital diagnostic monitoring is offered.
