The CWDM-SFP-1490-C is a Cisco-compatible, hot-pluggable 1000Base-CWDM SFP module operating at 1490 nm for single-mode fiber links up to 80 km.
This transceiver supports link lengths up to 80 km over standard single-mode fiber (SMF), assuming compliant fiber attenuation and splice loss.
The module supports a data rate of 1.25 Gbps, fully compliant with IEEE 802.3ah 1000BASE-BX standards.
It operates at a fixed wavelength of 1490 nm, part of the CWDM (Coarse Wavelength Division Multiplexing) grid.
Single-mode fiber (SMF) with an 8–10 µm core diameter and maximum attenuation of 0.4 dB/km is required.
Yes. It is Cisco-compatible via proper EEPROM signature and is interoperable with Cisco switches, routers, and DWDM/CWDM MUX/DEMUX systems.
It uses the Small Form-factor Pluggable (SFP) form factor with a duplex LC optical connector and a hot-plug design.
Yes. It conforms to SFF-8472 for DDM, providing real-time access to optical power, temperature, voltage, and bias current.
The module operates reliably from 0 °C to +70 °C (commercial temperature range) without performance degradation.
It requires a 3.3 V supply and consumes less than 1 W under maximum operating conditions.
Power down the port (if required), remove the protective caps, insert the transceiver until the latch clicks, then power up and verify link status.
Yes. As long as all modules comply with CWDM wavelength plans and IEEE 802.3 standards, multi-vendor interoperability is guaranteed.
Use show interface transceiver commands for DDM readings, or an optical power meter to confirm Tx/Rx power levels against specifications.
Cisco-compatible means the module mimics Cisco’s EEPROM vendor ID and SFP register profiles for seamless integration without error messages.
Refer to your CWDM channel plan and specify the required wavelength (e.g., 1490 nm) in your purchase order to match your MUX/DEMUX mapping.
