thanks for your response but I mean what connections are required between 16f877a and 4n35 and servo motor?

Connect the output pin of the pic to pin 1 of 4n35 via a resistor of 330 ohms connect pin 2 to digital ground. you can also place a led diode in series (between pic and opto to detect the state)
Pin 4 and 5 (4nn35) will be used to drive your servo (max current 150mA) if you need more current you must use a power transistor or a mosfet. Connect to analog ground pin 4 and pin 5 to your servo ground side. Connect the positive analog voltage directly to the servo.
When your pic pin will go high the opto will conduct switching on your servo.

I am sorry but i dont get exactly.Can you send any proteus file to here?
my servo is this http://www.rcuniverse.com/market/item.cfm?itemId=230128
what kind of circuit should I use?

Find enclose the schematic. You should separate the supply of the pic from the supply of the servo to avoid the electrical noise generated by the servo will disturb the functionality of your pic. Remember that 4N35 can supply a maximum current of 50 mA so if you want to use the schematic as it is, you must check that your servo does not need higher current. Naturally you do not need to change the software, because the wiring will give you a direct interfacing.
Hope this will solve your problem.

Forgive me i asked too many questions but i am a rookie about pic.my servo motor has three cable.+5 volt,ground and i have another cable as signal cable.Where do I connect signal cable??? Thank for your patience...

. . . . . If using the opto . . then to that . . . otherwise to the pic . . . . Why use the optoisolator . . .are you using some dangerous voltage, somewhere ? Or just trying to keep servo isolated from pic?Originally Posted by burak450

I am just trying to keep servo isolated from pic.my question is that where should I connect orange cable?
