Description

CWDM SFP for SONET/SDH OC-3/STM-1 over single‑mode fiber at the 1570 nm wavelength. Designed for dense wavelength transport via passive CWDM mux/demux systems, it features an LC duplex interface and hot‑swappable SFP form factor for rapid deployment in metro and transport networks.

Features

- CWDM 1570 nm for efficient wavelength utilization
- 155 Mb/s OC-3/STM-1 SONET/SDH operation
- SMF reach up to 80 km (budget dependent)
- LC duplex connector; easy service with hot-swappable SFP
- Ideal for metro transport via passive CWDM mux/demux
- Works in SFP slots supporting OC-3/STM-1 CWDM optics

FAQs

Q: Do both ends need the same wavelength?
A: Yes. For CWDM links, use the same wavelength (1570 nm) at both ends through the CWDM mux/demux.

Q: What fiber type is required?
A: Single-mode (9/125 µm) terminated with LC connectors.

Q: Is this suitable for Ethernet services?
A: No, it is intended for SONET/SDH OC-3/STM-1 circuits.

Q: What determines maximum reach?
A: Overall optical budget: transmitter power, receiver sensitivity, fiber attenuation, splices, and connector losses.

Q: Is it hot-swappable?
A: Yes, it uses the SFP form factor and supports hot-swap installation.
