omplementary Wavelength Pairing: To prevent signal collision on a single fiber, this module uses a specific wavelength offset:

Transmit (Tx): 1550 nm (Sends data out)

Receive (Rx): 1310 nm (Listens for incoming data)

WDM Technology: Uses Wavelength Division Multiplexing to differentiate between the "talk" and "listen" signals on the same physical glass core.

Industrial Hardening: Like its counterpart, it is rated for extreme environments (–40 °C to +85 °C), making it suitable for unventilated street cabinets or industrial sites.

Plug-and-Play (PnP): No software configuration is required on your Dahua switch; the hardware automatically negotiates the link once connected to its "T" version partner.
