Appendix D Transceiver modules
CAUTION:
To avoid damages to the transceiver, a compatible optical attenuation must be used if a short-haul
optical fiber is connected to a long-haul transceiver (40 km/24.86 miles or above). A loopback
occurs if you connect the receive optical bore to the transmit optical bore with a short-haul optical
fiber, as shown in
Figure 70 Loopback operation on a transceiver module
NOTE:
For the transceiver modules compatible with the modules, see the module manuals.
