3 contents of the HFBR-5720L serial id memory are defined in table 10 as specified in the sfp msa. transmitter section the transmitter section includes the transmitter optical subassembly (tosa) and laser driver circuitry. the tosa, containing an 850 nm vcsel (vertical cavity surface emitting laser) light source, is located at the optical interface and mates with the lc optical connector. the tosa is driven by a custom silicon ic, which converts differential logic signals into an analog laser diode drive current. this tx driver circuit regulates the optical power at a constant level provided the data pattern is valid 8b/10b balanced code. tx disable the HFBR-5720L accepts a transmit disable control signal input which shuts down the transmitter. a high signal implements this function while a low signal allows normal laser operation. in the event of a fault (e.g., eye safety circuit activated), cycling this control signal resets the module as depicted in figure 6. the tx disable control should be actuated upon initialization of the module. tx fault the HFBR-5720L module features a transmit fault control signal output which when high indicates a laser transmit fault has occurred and when low indicates normal laser operation. a transmitter fault condition can be caused by deviations from the recommended module operating conditions or by violation of eye safety conditions. a fault is cleared by cycling the tx disable control input. eye safety circuit for an optical transmitter device to be eye-safe in the event of a single fault failure, the transmitter will either maintain normal eye-safe operation or be disabled. in the event of an eye safety fault, the vcsel will be disabled. receiver section the receiver section includes the receiver optical subassembly (rosa) and amplification/ quantization circuitry. the rosa, containing a pin photodiode and custom transimpedance preamplifier, is located at the optical interface and mates with the lc optical connector. the rosa is mated to a custom ic that provides post-amplification and quantization. this circuit also includes a loss of signal (los) detection circuit which provides an open collector logic high output in the absence of a usable input optical signal level. loss of signal the loss of signal (los) output indicates that the optical input signal to the receiver does not meet the minimum detectable level for fibre channel compliant signals. when los is high it indicates loss of signal. when los is low it indicates normal operation. the loss of signal thresholds are set to indicate a definite optical fault has occurred (e.g., disconnected or broken fiber connection to receiver, failed transmitter). functional data i/o agilents HFBR-5720L fiber-optic transceiver is designed to accept industry standard differential signals. in order to reduce the number of passive components required on the customers board, agilent has included the functionality of the transmitter bias resistors and coupling capacitors within the fiber optic module. the transceiver is compatible with an ac-coupled configuration and is internally terminated. figure 1 depicts the functional diagram of the hfbr- 5720l. figure 3. transmitter eye mask diagram and typical transmitter eye. 0.8 0.5 0.2 0 x1 0.4 1-x1 normalized time normalized amplitude 1.0 1.0 0 1.3 0.6 ?.2
