I've a CPE connected to a 4506 switch. The interface is Up but I don't see traffic CPE MAC address on MAC sddes-table
I've already replaced the cable, SFP and port. Now I've the minimal config (nothing i.e. switchport access) and no MAC yet.

SFP is 1000Base-2BX10-D and I check the specifications. I saw the operation range for the SFP is RX: -3 to -19.5 and TX: -3 to -9.
When I type the command,
4506-1#sh int gi2/1 transceiver
ITU Channel not available (Wavelength not available),
Transceiver is internally calibrated.
If device is externally calibrated, only calibrated values are printed.
++ : high alarm, + : high warning, - : low warning, -- : low alarm.
NA or N/A: not applicable, Tx: transmit, Rx: receive.
mA: milliamperes, dBm: decibels (milliwatts).

So I think this is related with Fiber Optic link but the packets counters are incrementing.
ADD info :
Patched cable of 3M cable due to specification. Problem not solved.

Best Answer
You're not getting adequate signal for the receiver: -22 when it wants at least -19.5 dBm. Could be a bad/dirty connector, fiber trouble, etc.
My immediate suspicion is, however, the bone-simple one. I notice you are using a 1000Base-2BX10-D - is the other end also a 1000Base-2BX10-D, or is is it a 1000Base-2BX10-U? The two types must be used in pairs, one D (downlink) the other U (uplink) - the same type of single-fiber SFP is sometimes tagged A and B from other makers - they are also generally color-coded.
Since they work over one fiber by transmitting at one wavelength and receiving on a different one the transmitter on one end must match the receiver on the other, and vice versa. If both are sending on 1490 and listening on 1310, nothing works. Likewise, if one is transmitting on 1310 and listening on 1490, while the other is transmitting on 1490 and listening on 1550, the link won't work, even though one direction matches. You need one D transmitting on 1490 and listening on 1310 while the other U transmits on 1310 and listens on 1490 (more generally, for different Bi-Directional pairs, substitute in any matching set of wavelengths - 1550/1490, etc.)
Presumably the "wavelength not available" message relates to the excessively low signal on the receiver.
