Technical Specifications

FAQs

Q: Do I need optical attenuators at short distances?
A: Possibly. LR-2 transmit power can be high; use attenuation if receiver overload is indicated on short links.

Q: Is this compatible with Ethernet ports?
A: No. It is for SDH/SONET OC-3/STM-1 interfaces only.

Q: Can I mix LR-2 with LR-1 at the far end?
A: Use matching optical classes to ensure compatible power budgets and wavelengths.

Q: Does it support DDM/DOM?
A: Not specified; support depends on module revision and the host platform.
