The CMR4 is applied to the CWDM system. The channel spacing is 20 nm. The CMR4 supports the add/drop multiplexing function and channel expansion function.
Table 1 provides the functions and features of the CMR4.
| Function and Feature | CMR4 |
|---|---|
| Basic functions | Adds/Drops and multiplexes four signals to/from the multiplexed signals. |
| Channel expansion | Provides the interface to cascade another optical add/drop multiplexing board to realize the expansion of the add/drop channel. |
The feature code of the CMR4 contains eight characters, which indicate the wavelengths of the four channels of optical signals processed by the CMR4.
Table 1 describes the feature code of the CMR4.
| Feature Code | Indication | Description |
|---|---|---|
| 1st and 2nd characters | Wavelength of optical signals | The two characters are the two middle characters of the figure that indicates the wavelength of the first channel of optical signals processed by the CMR4. |
| 3rd and 4th characters | Wavelength of optical signals | The two characters are the two middle characters of the figure that indicates the wavelength of the second channel of optical signals processed by the CMR4. |
| 5th and 6th characters | Wavelength of optical signals | The two characters are the two middle characters of the figure that indicates the wavelength of the third channel of optical signals processed by the CMR4. |
| 7th and 8th characters | Wavelength of optical signals | The two characters are the two middle characters of the figure that indicates the wavelength of the fourth channel of optical signals processed by the CMR4. |
Consider the TN11CMR4 whose feature code is "47495961" as an example. The meaning of the feature code of the TN11CMR4 is as follows:
The technical specifications of the CMR4 include the parameters specified for optical interfaces, laser safety class, mechanical specifications, and power consumption.
Table 1 lists the parameters specified for the optical interfaces of the CMR4.
| Optical Interface | Parameter | Value |
|---|---|---|
| - | Operating wavelength range (nm) | 1291 to 1611 (1371 nm excluded) |
| - | Channel spacing (nm) | 20 |
IN-D1 IN-D2 IN-D3 IN-D4 | 0.5 dB passband bandwidth (nm) | ≥ ±6.5 |
| Insertion loss (dB) on the drop channel | ≤ 2 | |
| Adjacent channel isolation (dB) | > 25 | |
| Non-adjacent channel isolation (dB) | > 35 | |
A1-OUT A2-OUT A3-OUT A4-OUT | 0.5 dB passband bandwidth (nm) | ≥ ±6.5 |
| Insertion loss (dB) on the add channel | ≤ 2 | |
IN-MO MI-OUT | Insertion loss (dB) | ≤ 1.5 |
| Isolation (dB) | > 13 |
The safety class of the laser on the board is Class 1M. The maximum launched optical power of the optical interfaces is within the range from 10 dBm (10 mW) to 22.15 dBm (164 mW).
The mechanical specifications of the CMR4 are as follows:
The power consumption of the CMR4 at room temperature (25°C) is 0 W.
