10GB SFP+ DWDM Optical Transceivers
SFP+ transceivers are high performance,cost effective modules supporting data rate of 11.3Gbps and 40km/80km transmission distance with SMF. The transceiver consists of three sections: a cooled EML DFB laser transmitter, a PIN photo-diode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements.

FAQ About 10G SFP+ DWDM Optical Transceivers
A 10G DWDM SFP+ transceiver is a hot-pluggable optical module that supports 10 Gigabit per second (Gbps) data rates and uses Dense Wavelength Division Multiplexing to transmit multiple signals over a single optical fiber. It operates on specific wavelengths within the DWDM ITU grid (typically C-band, 1528.38–1563.86 nm) to enable high-capacity, long-distance data transmission.
- DWDM uses narrower wavelength spacing (0.4–0.8 nm), supporting up to 80–96 channels, ideal for long distances and high capacity.
- CWDM uses wider spacing (20 nm), supporting up to 18 channels, suited for shorter distances (up to 80 km) and lower costs.
DWDM is more expensive but offers greater scalability for dense networks.
Compatibility depends on the device and vendor:
- DWDM SFP+ modules follow the Multi-Source Agreement (MSA), ensuring broad compatibility.
- Some vendors may enforce firmware checks, requiring vendor-specific or programmable modules.
- Always verify the device’s compatibility matrix before deployment.
- DWDM multiplexers/demultiplexers to combine or separate wavelengths.
- Optical amplifiers (e.g., EDFA) for long-distance transmission.
- Dispersion compensation modules for ultra-long links to manage signal distortion.
Ensure the network infrastructure supports DWDM wavelengths.
- Distance: Select based on required reach (e.g., 40 km, 80 km).
- Wavelength: Fixed or tunable, matching your DWDM grid.
- Compatibility: Verify with your switch/router vendor.
- Environment: Ensure the module supports your operating temperature range.
- Budget: Balance cost with scalability needs.
