Juniper Networks M7I - Manual (Page 48)

• Duplex LC/PC connector (Rx and Tx); single-mode fiber
• SONET/SDH OC12/STM4 fiber-optic SFP transceivers:
• Short reach (model number: SFP-OC12-SR)
• Intermediate reach (IR-1) (model number: SFP-OC312-IR)
• Long reach (LR-1) (model number: SFP-OC12-LR)
Optical interface specifications—see SONET/SDH OC12/STM4 Optical Interface Specifications
Cables and connectors
One tricolor per port:
• Off—Not enabled
• Green—Online with no alarms or failures
• Yellow—Online with alarms for remote failures
• Red—Active with a local alarm; router has detected a failure
LEDs
