Recommended Circuit Schematics
Inputs C-1x-2500/C-Fx-SLCx series transmitters coupled internally terminated through ground. These transceivers operate with LVPECL logic levels. input signal must have least peak peak (single ended) signal swing. Output from receiver section module also coupled expected drive into load. Different termination strategies required depending particular Serializer/Deserializer chip used. C-1x-2500/C-Fx-SLCx series product family designed with coupled data inputs outputs provide following advantages: Close positioning SERDES with respect transceiver; allow shorter line lengths gigabit speeds reduces EMI. Mininum number external components. Internal termination reduces potential unterminated stubs which would otherwise increase jitter reduce transmission margin. Figure illustrates recommended transmit receive data line terminations SERDES with LVPECL Inputs/outputs respectively.

POWER COUPLING
suggested layout power ground connections given figure below. Connections made separate voltage ground planes. mounting posts case ground should connected circuit ground. mounting posts case gound should connected circuit ground. ferrite gead should provide real impedance ohms 1000MHz. Bypass capacitors should placed close 10-pin connector possible.

Printed Circuit Board Layout Consideration fiber-optic receiver employs very high gain, wide bandwidth transimpedance amplifier. This ampifier detects amplifies signals that only tens amplitude when receiver operating near limit. unwanted signal current that couples into receiver circuitry causes decrease receiver's senitivity also degrade receiver's signal detect(SD) circuit. minimize coupling unwanted noise into receiver, careful attention must given printed circuit board. minimun, double-sided printed circuit board (PCB) with large component side ground plane beneath transceiver must used. applications that include many other high speed devices, multi-layer highly recommended. This permits placement power ground separate layers, which allows them isolated from signal lines. Multilayer construction also permits routing signal traces away from high level, high speed signal lines. minimize possibility coupling noise into receiver section, high level, high speed signals such transmitter inputs clock lines should routed away possible from recevier pins. Noise that couples into receiver through power supply pins also degrade performance. recommended that filter both transmitter receiver supplied.
Considerations transceivers offer metalized plastic case special chassis grounding clip. shown drawing, this clip connects module case chassis grounding clip then installs flush through panel cutout. grounding clip this brushes edge cutout order make proper contact. grounding clip also provides increased electrostatic protection helps reduce radiated emissions from module host circuit board through chassis faceplate. attaching posts case potential connected chassis ground. They should connected circuit ground. Plastic optical subassemblies used further reduce possibility radiated emissions eliminating metal from transmitter receiver diode housings, which extend into connector space. proficing non-metal receptacle optical cable ferrule, gigabit speed electrical signal isolated from connector area thus preventing radiated energy leakage from these surfaces outside panel.
Laser Safety This single mode transceiver Class laser product. complies with 1040.10 1040.11. transceiver must operated within specified temperature voltage limits. optical ports module shall determinate with optical connector with dust plug.
