Transmitter Section

The transmitter section consists of a 850 nm VCSEL in an eye safe optical subassembly (OSA) which mates to the fiber cable.
The laser OSA is driven by a LD driver IC which converts differential input LVPECL logic signals into an analog laser driving
current.

TX_FAULT

When sensing an improper power level in the laser driver, the SFP set this signal high and turns off the Laser. TX_FAULT can be
reset with the TX_DISABLE line. The signal is in TTL level.

TX_DISABLE

The TX_DISABLE signal is high (TTL logic “1”) to turn off the laser output. The laser will turn on within 1ms when
TX_DISABLE is low (TTL logic “0”).

Receiver Section

The receiver utilizes a MSM detector integrated with a trans-impedance preamplifier in an OSA. This OSA is connected to a
circuit providing post-amplification quantization, and optical signal detection.

Receive Loss (RX_LOS)

The RX_LOS is high (logic “1”) when there is no incoming light from the companion transceiver. This signal is normally used by
the system for the diagnostic purpose. The signal is operated in TTL level.

Relative Input Optical Power (dB)

The figure shows the relationship between typical trade-off of BER and Relative Input Optical Power. Besides the

12



required BER =1  10

of the Gigabit Ethernet Physical Layer Standard, the transceiver can be operated at other Bit-

Error-Rate conditions. The Relative Input Optical Power in dB is referenced to the actual sensitivity of the device. For

12

BER conditions better than 1  10



, more input signal is needed (+dB).
