Stratos / Cinch Connectivity Solutions Front Load Optical Transceivers

The device combines transmitter and receiver functions. The optical transmitter is a high output 1310nm LED and the receiver consists of PIN and Preamplifier assemblies and CMOS limiting post-amplifier integrated circuits. The transmitter input lines are driven with differential LVPECL signals applied to the Transmit (TX+ and TX-) pins, converting the signals internally to a suitable modulation current by a CMOS integrated circuit.

Likewise, the receivers output consists of differential CML data signals on the Receive (RX+ and RX-) pins and a single-ended LVTTL loss of signal function on Loss of Signal (LOS) pin. When no optical signal is present, the RX data is suppressed (JAM) upon LOS Assert to prevent garbage data output. These characteristics make the FNF-LT11x Transceivers an excellent cost-effective solution with low profile.
