I have 9200 switch with TtenGigabitEthernet Transceiver Module. Connected through (not sure but will confirm tomorrow) WDM to another switch.

when do "sh interf tenGigabitEthernet 1/1/4"
TenGigabitEthernet1/1/4 is up, line protocol is up (connected)
Hardware is Ten Gigabit Etherne
MTU 1500 bytes, BW 1000000 Kbit/sec, DLY 10 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive not set
Full-duplex, 1000Mb/s, link type is auto, media type is 1000BaseLX SFP
input flow-control is on, output flow-control is unsupported
ARP type: ARPA, ARP Timeout 04:00:00
Last input 02:06:19, output 00:00:00, output hang never
Last clearing of "show interface" counters 00:46:44
Input queue: 0/2000/0/0 (size/max/drops/flushes); Total output drops: 0
Queueing strategy: fifo
Output queue: 0/40 (size/max)
5 minute input rate 0 bits/sec, 0 packets/sec
5 minute output rate 3000 bits/sec, 5 packets/sec
0 packets input, 0 bytes, 0 no buffer
Received 0 broadcasts (0 multicasts)
0 runts, 0 giants, 0 throttles
0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
0 watchdog, 0 multicast, 0 pause input
0 input packets with dribble condition detected
15565 packets output, 1179815 bytes, 0 underruns
Output 4969 broadcasts (0 multicasts)
0 output errors, 0 collisions, 0 interface resets
0 unknown protocol drops
0 babbles, 0 late collision, 0 deferred
0 lost carrier, 0 no carrier, 0 pause output
0 output buffer failures, 0 output buffers swapped out
There is output but no input. The other side has the same "there is output but no input".
The strange is, when the fiber is connected to a fiber-To-UTP converter, it works. When connecting the fiber port of the converter to the TtenGigabitEthernet of the switch, it works also.
How to find out the problem source?
