Description

Fixed optical attenuator for single-mode links requiring precise 7 dB loss, ideal for DWDM/CWDM power leveling, receiver protection, and lab/test environments. Low-reflection LC/UPC interfaces and broad 1260–1620 nm operating range ensure multi-rate compatibility across legacy and high-speed optics.

Features

- Precise fixed 7 dB attenuation for accurate power control
- Broadband SMF operation across O–L bands (1260–1620 nm)
- LC/UPC pass-through design for quick inline installation
- Multi-rate compatible from legacy to 400G optics
- Low-reflection UPC polish for stable link performance

FAQs

Q: Is this attenuator compatible with DWDM and CWDM optics?
A: Yes. Its 1260–1620 nm operating range makes it suitable for DWDM and CWDM systems as well as standard SMF links.

Q: Can I use it on high-speed links like 100G or 400G?
A: Yes. It is passive and multi‑rate compatible; select the attenuation value needed for your power budget.

Q: What connector polish does it use?
A: LC/UPC. If your plant is APC, use appropriate APC attenuators to match connector geometry.

Q: Where should I place the attenuator?
A: Typically near the receiver or as specified by your power budget to maintain receiver input within the recommended range.
