2. Transceiver Identification Test
        Pair the SFP-10G-BIDI-T1270/R1330-20KM-I-D14 and SFP-10G-BIDI-T1330/R1270-20KM-I-D14 transceivers with a 1-meter optical fiber and insert them into a Cisco N9K-C93180YC-EX switch. The transceivers establish a normal link with port indicators lit. The switch can accurately recognize transceiver information, including type, vendor name, model number, serial number, rate, and transmission distance. DOM data is readable, and all values are within the standard threshold with no alarms.
