Technical Specifications

FAQs

Q: What span length does LR-2 typically support?
A: LR-2 optics at 1550 nm are commonly specified for spans up to ~80 km, subject to total loss and dispersion.

Q: Do I need optical amplification or dispersion compensation?
A: For near-maximum spans, amplification and/or dispersion compensation may be required depending on fiber route characteristics.

Q: Is the module hardened for outdoor cabinets?
A: Yes, the industrial-temperature rating supports extended environmental conditions.

Q: Can this be used alongside CWDM/DWDM systems?
A: This is a fixed 1550 nm optic. For channelized DWDM/CWDM solutions, use wavelength-specific transceivers designed for those systems.
