Technical Specifications

FAQs

Q: Is this module tunable?
A: No. It is a fixed-wavelength DWDM SFP+ at 1540.56 nm per the ITU-T 100 GHz grid.

Q: What fiber and connector type is required?
A: Single-Mode Fiber (SMF) with LC duplex connectors.

Q: How far can it reach?
A: Up to 80 km on suitable SMF links, subject to optical budget, span loss, and DWDM components.

Q: Does it support DOM/DDM?
A: Yes, digital diagnostics monitoring is supported.

Q: Can I use it without a DWDM mux/demux?
A: It can operate point-to-point at its fixed wavelength, but it is primarily intended for DWDM systems.
