Cisco Compatible SFP+ CWDM Modules

A

A Cisco Compatible SFP+ CWDM module is a hot-swappable 10 Gigabit pluggable transceiver that uses coarse wavelength division multiplexing to increase fiber capacity while remaining fully interoperable with Cisco optics ports.

A

CWDM uses wider channel spacing (20 nm) for up to 18 channels at lower cost and power, while DWDM uses narrower spacing (0.8 nm) for many more channels but at higher complexity and expense.

A

Modules are offered in standard CWDM ITU channels from 1271 nm to 1611 nm, covering wavelengths: 1271, 1291, 1311, 1331, 1351, 1371, 1391, 1411, 1431, 1451, 1471, 1491, 1511, 1531, 1551, 1571, 1591, and 1611 nm.

A

Up to 40 km on single-mode fiber (SMF) at 1310 nm with a standard optical link budget, depending on fiber quality and channel count.

A

Yes. They adhere to MSA specifications (SFF-8431, SFF-8472) and Cisco’s transceiver compatibility requirements for seamless plug-and-play operation.

A

Single-mode fiber (SMF) with an 8.3/125 µm core is required to support CWDM wavelengths and minimize dispersion over long distances.

A

Yes. These SFP+ CWDM transceivers support hot-swap functionality, enabling insertion or removal without powering down the host device.

A

1. Power on the switch. 2. Remove protective caps. 3. Insert the module into the SFP+ slot until it clicks. 4. Connect LC fibers matching transmit/receive ends.

A

Use your device CLI: ‘show interface transceiver details’ or ‘show hw-module subslot optics status’. Check DDM parameters like temperature, voltage and optical power.

A

Cost-effective fiber utilization via multiplexing, simplified network expansion, lower power and cooling requirements compared to DWDM, and guaranteed Cisco compatibility.

A

Yes. They meet Multi-Source Agreement (MSA) standards SFF-8431 for electrical and SFF-8472 for digital diagnostics monitoring, ensuring universal compatibility.

A

Verify correct wavelength pairing, inspect fiber integrity, check DDM RX/TX power levels, confirm module compatibility, and replace suspected faulty modules or cables.

A

Typical link budget ranges from 9 to 13 dB, depending on wavelength, vendor tolerances, and fiber attenuation characteristics.

A

They comply with IEEE 802.3ae (10G Ethernet), ITU-T G.694.2 (CWDM), RoHS, and optional TAA country of origin requirements.

A

Map your link’s fiber count to ITU channel plan, avoid overlapping wavelengths, and select modules in matching transmit (Tx) and receive (Rx) pairs.

Standard stock availability is 3–5 business days; customized wavelengths or bulk orders may require 7–10 business days depending on supplier inventory.
