1431nm, 1451nm, 1471nm, 1491nm,. 1511nm, 1531nm, 1551nm, 1571nm, 1591nm and 1611nm, compatible 30dB. The transmitter section of FTM-6112C-SLxxxxxG incorporates a highly reliable uncooled DFB laser and the receiver section utilizes a PIN/APD receiver. All modules satisfy Class 1 Laser Safety requirements. FTM-6112C-SLxxxxxG provides an enhanced with ITU-T G694.2. It offers a guaranteed minimum optical link budget of 22dB or
monitoring interface, which allows real-time 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 a sophisticated system of alarm and warning flags, which alerts end-users when particular operating parameters are outside of a factory set normal range. FTM-6112C-SLxxxxxG is compliant with RoHS.

Regulatory Compliance
The transceivers have been tested according to American and European product safety and electromagnetic compatibility regulations (See Table 1). For further information regarding regulatory certification, please refer to Fiberxon regulatory specification and safety guidelines, or contact with Fiberxon, Inc. America sales office listed at the end of documentation. Table 1 - Regulatory Compliance Feature Electrostatic Discharge (ESD) to the Electrical Pins Electrostatic Discharge (ESD) to the Duplex LC Receptacle Electromagnetic Interference (EMI) Immunity Laser Eye Safety Component Recognition RoHS Note: In light of item 5 in Annex of 2002/95/EC, "Pb in the glass of cathode ray tubes, electronic components and fluorescent tubes." and item 13 in Annex of 2005/747/EC , " Lead and cadmium in optical and filter glass." ,the two exemptions are being concerned for Fiberxon's transceivers, because Fiberxon's transceivers use glass, which may contain Pb, for components such as lenses, windows, isolators, and other electronic components.

TX Fault is an open collector output, which should be pulled up with a 4.7k~10k resistor on the host board to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates a laser fault of some kind. In the low state, the output will be pulled to less than 0.8V. 2. TX Disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a 4.7k~10k resistor. Its states are: Low (0~0.8V): (>0.8V, <2.0V): High (2.0~3.465V): Open: Transmitter on Undefined Transmitter Disabled Transmitter Disabled Name VeeT TX Fault TX Disable MOD-DEF2 MOD-DEF1 MOD-DEF0 Rate Select LOS VeeR VeeR VeeR RDRD+ VeeR VccR VccT VeeT TD+ TDVeeT Function Transmitter Ground Transmitter Fault Indication Transmitter Disable Module Definition 2 Module Definition 1 Module Definition 0 Not Connected Loss of Signal Receiver Ground Receiver Ground Receiver Ground Inv.

3. MOD-DEF 0,1,2 are the module definition pins. They should be pulled up with a 4.7k~10k resistor on the host board. The pull-up voltage shall be VccT or VccR. MOD-DEF 0 is grounded by the module to indicate that the module is present MOD-DEF 1 is the clock line of two wires serial interface for serial ID MOD-DEF 2 is the data line of two wires serial interface for serial ID 4. LOS is an open collector output, which should be pulled up with a 4.7k~10k resistor on the host board to a voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates loss of signal. In the low state, the output will be pulled to less than 0.8V. 5. These are the differential receiver output. They are internally AC-coupled 100 differential lines which should be terminated with 100 (differential) at the user SERDES.
