Description
Fiberxon 155M 2.67Gbps Spring-latch SFP
Features
Support 155M2.67Gbps multi-rate data links 1310nm 1550nm uncooled uncooled DFB DFB laser laser and and APD APD photodiode for 40km transmission photodiode for 80km transmission Digital diagnostic monitor interface compatible with SFF-8472 SFP MSA package with duplex LC connector With Spring latch for high density application Class I laser product Hot-pluggable capability Operating case temperature: 0 to +70
transceiver is high performance, cost effective module that supports data-rate up to 2.67Gbps and transmission distance from 40km to 80km. The transceiver consists of two sections: The transmitter section incorporates an uncooled DFB laser, and the receiver section consists of APD integrated with a trans-impedance preamplifier (TIA). All modules satisfy class I laser safety requirements. The optical output can be disabled by a TTL logic high-level input of Tx Disable. Tx Fault is provided to indicate degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver. The transceiver provides an enhanced monitoring interface, which allows real time access to the transceiver transceiver operating temperature, parameters laser bias such as current,

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 FlexonTM regulatory specification and safety guidelines, or contact Fiberxon, Inc. America sales office listed at the end of the 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.

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
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 grounded by the module indicates that the module is present MOD-DEF 1 is the clock line of two-wire serial interface for serial ID MOD-DEF 2 is the data line of two-wireserial 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 outputs. They are AC-coupled 100 differential lines which should be terminated with 100 (differential) at the user SERDES. 6. These are the differential transmitter inputs. They are AC-coupled, differential lines with 100 differential termination inside the module.
