Single-mode/multimode fibers and single-mode/multimode optical modules cannot be mixed. For details about the optical modules supported by optical ports on switches, see "Appearance and Structure" of a specific switch model in the Hardware Description. These small but powerful plugins use a 1310nm laser to push signals through single-mode fiber, reliably reaching up to 10km. On an optical network, a sender needs to convert electrical signals into optical signals before sending them to a receiver, and the receiver needs to convert received optical signals into electrical signals.

To check the status of SFP modules on Juniper devices, utilize the command "show interfaces diagnostics optics" to retrieve detailed information about the SFP module status and transceiver data for various types of optical transceivers (SFP, SFP+, XFP, QSFP+, CFP) installed in. The information provided by this command is known as digital optical monitoring (DOM) information. During times, Juniper OS has offered different command versions to display transceiver information – legacy Juniper show SFP type, to nowadays versions show interfaces diagnostics. Their most popular Operating Software (OS) is named Junos OS, with the latest version today, 22.
