Troubleshooting Of Fiber Media Converter

1, the Power light does not shine

Power failure encountered in the Power light does not shine, just direct replace the transceiver or the power supply box, but the socket replaced before test voltage is normal, so as not to cause damage once.

2, the optical path Link light does not shine

a) Check the fiber optic cable line is open circuit, the available loopback test method or with optical power meter and light source testing.

b) power meter check the fiber line loss is beyond the scope of equipment to receive different transceiver reception range should be confirmed according to the actual situation.

c) Check whether the optical interface docking with the flange correctly.

d) Check the fiber optic interface transceiver is correct, the test commonly used transceiver swap.

e) transmission length and distance match, especially over long distances must be selected can reach the distance of Fiber Media Converter.

f) both ends of the transceiver model match the model of the card more mixed interpolation may lead to unreasonable or other faults.

g) transceiver to connect the fiber mode matching, single-mode card to use single-mode fiber, multimode card use multimode fiber.

h) damage to the port transceiver light from the Tour de France tests, such as ring, the Link light is still not lit, then judge for the optical interface failures.

3, the circuit Link light does not shine

a) Check the network cable is open circuit or bad contact.

b) Check the connection type to match some of the fiber optic transceiver does not yet support adaptive, according to the type of connection to select a crossover cable or straight cable.

c) to inspect equipment, the transfer rate to match, if not adaptive, when both ends of the mandatory rate mismatch may cause transmission interruptions.

d) switches Optical port is disable.

e) The transceiver circuit port is damaged.

4, the network packet loss is a serious

a) fiber optic transceiver damage, lightning or high-voltage transient packet loss in general can determine the transceiver damage.

b) The transceiver's power port and the Network Device Interface, or both ends of the device interface duplex mode mismatch.

c) fiber optic connectivity issues, line attenuation reaches a critical state often this happens.

d) The cable quality issues.

5, send and receive lights are normal, but the network is disconnected

a) and the upper switch port does not match the check is not easy to find fault, from the physical layer.

b) The transceiver is damaged, or hanged.

c) cable production error, the wrong fiber jumper production also make electrical port link lights, but the link does not conduction.

d) The single fiber conduction, some transceiver just received optical signal optical port LINK light to light up, at which point there is no light signal is sent.

7, commonly used in transceiver test methods

a) the substitution method: When a spare transceiver, using the substitution method to forensics transceiver problem is the most direct and quick way.

b) stand-alone test method: put aside the external connection circuit, stand-alone transceiver test directly connected, such as able to ping the General Principles of judgment for the transceiver to normal, if not to ping you need to check the upper fault.

c) both ends of the test method: both ends of the transceiver connected computer if ping, ping General Clauses exclude transceiver failure, such as the ping fails you need to check the reasons for the connection from the transceiver, the optical path network cable.
