Description
The Pixietech SFP28 25G WDM optical module is the second half of the pair that carries 25 Gbps over a single fiber. It transmits at 1270 nm and receives at 1330 nm — mirroring PXT-SFP28-W37-20 — and is installed at the opposite end of the line. A reach of up to 20 kilometers covers links between sites within a city.
Advantages
- One fiber instead of two — saves an expensive fiber resource
- 25 Gbps at distances up to 20 km
- Frees half the ports on the optical patch panel
- Installed without stopping the equipment; hot swap supported
- DDM diagnostics: monitoring of optical power and temperature
- One-year Pixietech warranty
Applications
- Densifying live fiber lines at telecom operators
- Links between a company's offices over leased fiber
- Metro access networks short of spare fibers
- Connecting remote surveillance nodes at high speed
- Backup links where dedicating two fibers makes no sense
Frequently asked questions
Does this module replace W37 or work alongside it?
Alongside: W73 at one end of the line, W37 at the other. Separately they do not work.
Is a special patch panel or splice closure required?
No, an ordinary single-fiber line and standard LC adapters are used.
How do I know which module goes at which end?
The roles are equivalent; what matters is only that the two ends carry different models — W37 and W73.
