FAQs

Q: Is this module tunable?
A: No. It is a fixed-wavelength DWDM XENPAK at 1534.25 nm.

Q: What fiber and connector are required?
A: Single-mode fiber (9/125 µm) with LC duplex connectors.

Q: Does it support DOM?
A: Yes, digital optical monitoring is supported.

Q: What is the maximum reach?
A: Up to 40 km on standard SMF without amplification, dependent on loss budget and link quality.

Q: Can it interoperate with other vendors’ DWDM optics?
A: Yes, provided the wavelength, optical standard (10GBASE-ER), and link budget match.

Q: Is it hot-swappable?
A: Yes, it can be inserted and removed without powering down the host device.
