Description

Fixed-wavelength 10G DWDM SFP+ transceiver for long-reach single-mode links. Supports 10GBASE-ER over OS2 fiber up to 40 km, with digital diagnostics (DOM) and LC duplex interface. Tuned to 1546.92 nm on the ITU-T DWDM C-band grid; ideal for dense wavelength multiplexed backbone and metro links. Actual reach depends on fiber loss, splices, and dispersion.

Features

- DWDM 10G long-reach optics for metro/backbone links
- Fixed 1546.92 nm channel for dense wavelength deployments
- Up to 40 km over OS2 SMF with LC duplex interface
- Standards-compliant 10GBASE-ER with DOM monitoring
- Hot-swappable SFP+ for rapid service turn-up

Technical Specifications

FAQs

Q: Is this module tunable?
A: No. It is a fixed-wavelength DWDM SFP+ tuned to 1546.92 nm.

Q: What fiber type is required?
A: Single-mode OS2 fiber with duplex LC connectors.

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

Q: Will it reach 40 km without amplification?
A: It supports up to 40 km under typical link budgets; actual distance depends on fiber attenuation, splices, and connector losses.

Q: Is dispersion compensation needed?
A: Generally not for 10GBASE-ER up to the specified reach, but confirm with your link budget and fiber characteristics.

Q: What devices is it compatible with?
A: Any 10G SFP+ port that supports 10GBASE-ER DWDM optics and the required wavelength; vendor-specific compatibility policies may apply.
