Description

DWDM SFP transceiver for OC-48/STM-16, providing fixed ITU-grid wavelength operation over single-mode fiber with hot-swap convenience. Ideal for dense channel multiplexing in metro core and long-haul optical networks where precise wavelength alignment is required.

Features

- OC-48/STM-16 SONET/SDH compatibility
- Fixed ITU-grid DWDM wavelength for dense multiplexing
- SFP hot-swap form factor for rapid service
- LC duplex interface on single-mode fiber
- Long-haul ready when paired with appropriate amplification/dispersion solutions

FAQs

Q: Is this SFP suitable for OC-48/STM-16 DWDM ports?
A: Yes. Use it in ports that explicitly support DWDM SFPs for OC-48/STM-16 rates.

Q: Is it tunable?
A: No. It is a fixed-wavelength DWDM transceiver; select the exact wavelength required by your channel plan.

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

Q: Can I mix this with CWDM optics?
A: No. It is a DWDM optic and should be used with DWDM MUX/DEMUX and matching ITU channels.
