Stiletto Pluggable Optical Transceiver

Optical Transceiver Product

Moog Protokraft Stiletto series optical fiber transceivers consist of 10 Gbps optoelectronic transmitter and receiver functions integrated into a pluggable Duplex LC compliant connector. The optical harsh environment transmitters are 850 nm VCSEL lasers. The transmitter input lines are driven with differential CML signals applied to the transmitter (TX+ and TX-) lines. Dual loop, temperature compensated, VCSEL drivers convert the transmitter input signals to suitable VCSEL bias and modulation currents.

Outputs from the receivers consist of differential CML data signals on the receiver (RX+ and RX-) lines. An LVTTL signal is generated on the Loss of Signal (LOS) line upon receipt of an invalid incoming optical signal. The receiver data lines are squelched upon LOS assertion, preventing errant data generation when an invalid incoming optical signal is presented to the transceiver.

Stiletto series optical fiber transceivers support the 2-wire serial communication protocol as defined in SFF-8472, offering end user access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage. It also defines alarm and warning flags, to alert end users when particular operating parameters are outside of a factory defined normal range.

The electrical interface to the Stiletto optical transceivers is a Samtec® SMT Connector with a 20 position footprint which makes it a pluggable transceiver perfectly suited for harsh environmental applications.

Typical Applications

The multimode optical fiber interface supports applications where copper cable link distance, bandwidth, weight or bulk make the use of twisted pair, twinax or quadrax copper conductors unacceptable.
