Juniper Networks devices support a variety of fixed and pluggable transceivers and network cable, including multimode and single-mode fiber-optic cable. We strongly recommend that only transceivers qualified for Juniper Networks be used on Juniper Networks devices. Different transceiver types (long-range, short-range, copper, and others) can be used together on multiport interface modules as long as they are qualified by Juniper Networks. We cannot guarantee that the interface module will operate correctly if third-party transceivers are used.
