What is the optical receiver sensitivity for this 40km 10G DWDM SFP+ module, and is an inline optical attenuator needed during short-distance bench staging?

This module is equipped with a high-performance PIN receiver photodiode offering a sensitivity of -15.5dBm and a receiver overload threshold around -0.5dBm. For short-distance bench testing (e.g., under 5km or direct fiber loopback), inserting a 3dB to 5dB LC optical attenuator is recommended to avoid receiver saturation and ensure optimal Bit Error Rate (BER) performance.

Can this industrial DWDM C23 1558.98nm transceiver be used with passive 100GHz CWDM MUX/DEMUX units or does it require a dedicated DWDM filter panel?

This module operates on the ITU 100GHz grid (C23 / 1558.98nm) and requires a dedicated DWDM MUX/DEMUX multiplexer filter. CWDM filters have much wider channel spacing (20nm) and different channel centers, so a DWDM module will not pass traffic properly through standard CWDM filter ports.

How does the industrial temperature rating (-40°C to 85°C) affect the wavelength stability of the 1558.98nm EML laser transmitter under extreme thermal swings?

The module utilizes an integrated Thermo-Electric Cooler (TEC) and internal wavelength locking mechanism paired with the EML laser. This active thermal control keeps the laser diode temperature stable, preventing ITU C23 100GHz center frequency drift even when ambient enclosure temperatures fluctuate from -40°C to +85°C.
