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 72 .
