Questions & Answers
What is the CWDM-SFP-1590-40-C module?
The CWDM-SFP-1590-40-C is a Cisco-compatible 1000Base-CWDM SFP transceiver operating at 1590 nm for Gigabit Ethernet links up to 40 km over single-mode fiber.
Which wavelength does the CWDM-SFP-1590-40-C use?
It operates at a center wavelength of 1590 nm, following ITU-T CWDM channel specifications for minimal crosstalk in multi-channel deployments.
What is the maximum transmission distance?
The module supports a link length of up to 40 km (24.8 miles) over ITU-T G.652 single-mode fiber at 1310 nm attenuation rates.
Which network standard does it support?
It complies with the IEEE 802.3ah 1000Base-CWDM standard for Gigabit Ethernet transport on CWDM wavelengths.
Is the CWDM-SFP-1590-40-C compatible with Cisco hardware?
Yes. It is fully Cisco-compatible and interoperates with Cisco switches and routers without requiring proprietary firmware or licenses.
What fiber type and connector does it require?
It requires ITU-T G.652 single-mode fiber with LC duplex connectors for both transmit and receive interfaces.
Can I hot-swap the CWDM-SFP-1590-40-C module?
Yes. The module is hot-pluggable, allowing safe insertion and removal without powering down the host device.
What is the operating temperature range?
The module operates reliably from –5 °C to +70 °C (23 °F to 158 °F) for standard commercial installations.
What are the optical power specifications?
Transmit power ranges from –3.0 dBm to 0.0 dBm; receive sensitivity is –24.0 dBm maximum, ensuring a power budget suitable for 40 km links.
How do I install the CWDM-SFP-1590-40-C module?
Align the module with the SFP slot, insert until it latches, connect LC duplex fiber, then verify the LED link/activity indicator on the host.
Does it require special licensing on Cisco devices?
No. The module is recognized as a standard SFP by Cisco IOS and requires no additional licensing or software keys.
