Juniper Networks M20 Network Router User Manual


 
You can install any transceiver supported by the PIC. For information about installing
and removing transceivers, see the PIC and Transceiver Installation Instructions.
NOTE: Do not install SONET/SDH SFPs in the Gigabit Ethernet port. The port will not recognize
the SFP.
Fiber-optic SX, LX, and LH small form-factor pluggable transceivers (SFPs):
Connector: Duplex LC/PC (Rx and Tx)
Optical interface supportSee Table 14 on page 54
Copper 1000Base-T SFPs:
Connector: Four-pair, Category 5 shielded twisted-pair connectivity through an RJ-45
connector
Pinout: MDI crossover
Length: 328 ft/100 m
Cables and connectors
