8CH MWDM Mux Module 1271.5–1341.5nm 10nm Spacing Low Insertion Loss FC UPC 100*80*10mm ABS Box,Passive Optical Components

1. Product Overview

This 8-channel MWDM multiplexing module combines eight optical signals within the 1271.5nm to 1341.5nm range into a single common port. The eight channels are spaced 10nm apart and are designated as 1271.5, 1281.5, 1291.5, 1301.5, 1311.5, 1321.5, 1331.5, and 1341.5nm, suitable for O-band multi-wavelength transmission and customized optical communication systems.

2. Key Features

• 8-Channel MWDM Multiplexing Design
• Combines eight different wavelength input signals into a single common fiber optic port.
• 1271.5–1341.5nm Channel Range
• Coverages eight MWDM operating channels with a 10nm channel spacing.
• ±3nm Passband Range
• Each channel has a passband range of ±3nm, with a measurement reference point of −0.5dB.
• Low Channel Insertion Loss
• Insertion loss (IL) ≤ 3.0 dB, helping to control the optical power budget of multi-channel links.
• Low Passband Ripple
• Ripple ≤ 0.5 dB, reducing loss fluctuations at different wavelengths within the passband.
• Channel Isolation Performance
• Adjacent channel isolation > 25 dB, non-adjacent channel isolation > 35 dB.
• High Directivity and Return Loss
• Directivity (DIR) ≥ 50 dB, return loss (RL) ≥ 45 dB.
• Low Polarization Dependent Loss (PDL) ≤ 0.1 dB, reducing the impact of input polarization state variations on transmission performance.
• FC/UPC Connector Configuration
• FC/UPC connectors are configured on all channels and the common terminal.
• 100% End-Face 3D Inspection
• Connector end-face geometry and cleanliness are inspected to control end-face defects and assembly consistency.
• Box-Type Packaging Structure
• Uses a 100*80*10mm ABS box for easy internal installation and fiber management.

4. FAQ

1. Q1: What operating wavelengths does this module contain?

   This MUX module contains the following eight channels:

   Channel	Center Wavelength
   CH1	1271.5nm
   CH2	1281.5nm
   CH3	1291.5nm
   CH4	1301.5nm
   CH5	1311.5nm
   CH6	1321.5nm
   CH7	1331.5nm
   CH8	1341.5nm

   The channel spacing is 10nm.

2. Q2: What is the function of the MUX module?

   The MUX module combines eight independent wavelength optical signals into a common port, enabling multiple signals to be transmitted through a single optical fiber. The receiver typically requires a DEMUX module to separate each channel.

3. Q3: What are the main optical performance characteristics?

   Parameters	Specifications
   Channel Insertion Loss	IL≤3.0dB
   Passband Ripple	≤0.5dB
   Return Loss	RL≥45dB
   Directivity	DIR≥50dB
   Polarization Dependent Loss	PDL≤0.1dB
   Adjacent Channel Isolation	>25dB
   Non-Adjacent Channel Isolation	>35dB
   Maximum Optical Power	≤300mW

4. Q4: What are the fiber optic pigtail and connector configurations?

   The module uses 0.9mm white loose tubing. The pigtail length, including the FC/UPC connector, is 100±3cm. FC/UPC connectors are configured on the common end and all eight channel ends.

5. Q5: What are the module dimensions?

   The standard ABS box package dimensions are 100*80*10mm.

6. Q6: Why is 3D connector inspection necessary?

   3D inspection is used to confirm geometric parameters such as the radius of curvature, fiber height, and apex offset of the connector end face. Combined with end face cleaning and defect inspection, it can reduce the risk of abnormal connection loss and unstable end face contact.

7. Q7: Is a DEMUX version of the product available?

   A DEMUX module can be designed according to the same channel wavelength configuration. The port orientation and insertion loss requirements for MUX and DEMUX need to be confirmed separately in the order.

8. Q8: Does the product support other channel or interface configurations?

   The number of channels, center wavelength, pigtail length, connector type, and packaging can be adjusted according to project requirements. Specific specifications need to be confirmed before production.
