Four-Wavelength, Four-Channel Output Lan WDM Light Source

Basic concepts of Lan WDM light source:

1. From the wavelength points: wavelength is defined as the L1:1271/1291/1311/1331 nm and L2:1295.56/1300.05/1304.58/1309.14 nm. Other wavelength combinations are named L3, L4,...

2. From the packaging form of light emitting devices, it is divided into: the first group L1, there are two kinds of packaging of coaxial devices and butterfly devices, and the second group L2, generally for butterfly device packaging. We define the coaxial package device as U8154-T (TO) and the Butterfly package device as U8154-B (Butterfly).

3. Divided from four wavelength output forms: there are four wavelengths divided into four outputs, and four wavelengths combined with one output; We define the four-wavelength four-way output as U8154 and the four-wavelength four-way output as U8151.

4. From the form of power output: general users need four wavelength equal power output, some users need four wavelength each power adjustable output (adjustable range of 30dB), we define equal power output as: U8154-P, power adjustable output U8154-V;

What is LANWDM?

The full name of LWDM is LAN WDM, which usually refers to a wavelength range dense wavelength division multiplexing technology using four wavelength division multiplexing technology in 100G optical modules. According to the LAN WDM wavelength defined by IEEE 802.3, it mainly covers 10km. Wavelength of 1295.56 nm and 1300.05 nm and 1304.58 nm and 1309.14 nm four wavelengths.
