Model: Huawei Optical Modules

Basic Information:

The Huawei Optical Modules are designed for high speed data transmission over long distances. The specific model in question is the 1.25G TX 1310nm RX 1490nm 10km SM BIDI SFP, which is part number 34060470. This module is compatible with SFP (Small Form factor Pluggable) transceivers, making it suitable for use in various networking devices that support SFP interfaces.

Transmitter Characteristics:

The transmitter section of the module operates at a wavelength of 1310nm, which is a common wavelength for telecommunications. It is designed to transmit data at a rate of 1.25 Gbps (Gigabits per second). The transmitter's output power is typically around  3 dBm to +3 dBm, ensuring reliable signal transmission over the specified distance.

Receiver Characteristics:

The receiver section of the module operates at a wavelength of 1490nm, which is another common wavelength used in telecommunications. It is designed to receive data at the same rate of 1.25 Gbps. The receiver's sensitivity is typically around  26 dBm to  30 dBm, which means it can detect signals with very low power levels, ensuring high quality reception even over long distances.

BIDI (Bidirectional) Feature:

The BIDI feature of this module allows it to transmit and receive signals simultaneously over a single fiber strand, effectively doubling the capacity of the fiber link. This is achieved by using two different wavelengths for transmission and reception (1310nm for TX and 1490nm for RX), which are separated by a WDM (Wavelength Division Multiplexing) filter within the module.

Distance Capability:

This module is designed for long distance transmission, with a specified range of up to 10 kilometers. This makes it suitable for use in wide area networks (WANs) and other applications that require high speed data transmission over extended distances.

In summary, the Huawei 1.25G TX 1310nm RX 1490nm 10km SM BIDI SFP (part number 34060470) is a high performance optical module that offers reliable and efficient data transmission over long distances. Its BIDI capability and compatibility with SFP interfaces make it a versatile solution for various networking applications.
