BD-24E1-GE-CON is a Gigabit Ethernet aggregator with inverse multiplexing and VLAN TAG function; it provides three gigabit Ethernet interfaces (2 electrical and 1 optical Ethernet interfaces) compliant with IEEE 802.3 series standard and up to 24 E1 interfaces. It can separate the Ethernet data from GE port (the carried VLAN Tag correspond to different VCG channels), encapsulate them into EoPDH signal, and then into E1 signal; in the opposite direction, it can de-map the Ethernet data from E1 signal, aggregate them into GE port.

The BD-S36048PFM is a full gigabit managed PoE switch. It has 48*10/100/1000Base-T RJ45 ports and 4*100/1000Base-X SFP fiber slot ports. Port 1-48 can support IEEE802.3af/at standard PoE power supply. single port PoE power reaches 30W. As a PoE power supply device, it can automatically detect and recognize the power receiving equipment that meets the standard and supply power through the network cable. It can supply power to POE terminal equipment such as wireless AP, webcam, VoIP phone, building visual access control intercom, etc. through network cable, to meet the network environment that needs high-density PoE power supply.It is suitable for hotels, campuses, parks, shopping malls, scenic spots, hospitals, factory dormitory and small and medium-sized enterprise.
It has 7 function modules: RF control, DFB laser, optical modulator, SBS control, CSO control, communication/display control and power supply. Automatic gain control circuit (AGC) or manual gain control circuit (MGC) amplifies the RF signal. AGC or MGC control makes the optical modulator maintain a suitable input level. Use the detected RF root-meansquare(RMS)-total power to calculate the optical modulation index(OMI). In general we recommend using the AGC function, and special users can use the MGC function to adjust the CNR/CSO/CTB performance indexes. The core of transmitter is the optical modulator. The 1550nm signal input the optical modulator, make the laser intensity changed follow the external RF signal voltage, and then generate the AM optical signal. Stimulated Brillouin Scattering (SBS) occurs, when the optical input power is greater than a certain threshold value. SBS generate the lower frequency backscattered light which will attenuate the transmission light and return to the laser while destroying its performance. Causing optical power fluctuation, generates large noise, and seriously deteriorates the system carrier to noise ratio (CNR). To improve the SBS threshold, this optical transmitter adopts SBS control technology which is independent researched and developed by ourselves. The threshold value can be set up to 19dBm. The optical modulator has a two-way optical signal output. Parts of that signal are routed to an InGaAs photodiode. This detection of the optical signal has two functions: 1) Detect whether the laser is normal working. Once the output optical power is 2dB lower than standard power, alarm will be set off. 2) Detect CSO distortion to optimize the bias point of the optical modulator. For working normal the detector circuit needs at least two carrier signal inputs with an interval of 24MHz. There is a CSO initialization program in the boot process. If the CSO install failed, the RF indicator will flash red, see details in 6.2 Troubleshooting.
