TEOSCO has released complete 100G QSFP28 series, it includes QSFP28 SR4, LR4, ER4, CWDM4, PSM4, CLR4, QSFP28 AOC cables and QSFP28 DAC cables.

TEOSCO is pleased to announce that our 96 Channel DWDM Mux/Demux is released. This will greatly improve your network connection. Our range of passive DWDM multiplexers allow up to 90 DWDM channels to be connected simultaneously over a dark fiber network now. They are protocol transparent and suit applications including 10/1GEthernet, SDH/SONET,16/8/4/2/1GFibre Channel/FICON, FTTx and CATV.

DDM (Digital Diagnostic Monitoring) is a technology that users can monitor the real-time parameters of optical transceivers, including working temperature, voltage, current, transmitting and receiving optical power, etc. Besides, it can also show the optical wavelength, data rate, transmission distance, manufacturer‘s name, model, serial number, date, alarm information, etc. But electrical interface modules are without DDM function.

Transmitting optical power refers to the output optical power of the light source at the transmitting end of the optical transceiver, the unit is dBm. Receiving sensitivity refers to the minimum received optical power of an optical transceiver at a certain rate, the unit is also dBm. In general, the higher the rate, the worse the receiving sensitivity, that is, the greater the minimum received optical power, and the higher the requirements for the receiving end devices of the optical transceiver.

During the use of the optical transceiver, there will be light attenuation and packet loss. The technicians may consider the quality of the module and the line attenuation. However, there is one thing that must not be ignored, that is, the cleaning of the optical module.

Teosco Thermal/Athermal AWG products include 50GHz, 100GHz and 200GHz. Athermal AWG(AAWG) have equivalent performance to standard Thermal AWG(TAWG) but require no electrical power for stabilization. They can be used as direct replacements for Thin Film Filters(Filter type DWDM module) for cases where no power is available, also suitable for outdoor applications over -30 to +70 degree in access networks. Teosco AAWG provides excellent optical performance, high reliability, ease of fiber handling and power saving solution in a compact package. Different input and output fibers, such as SM fibers, MM fibers and PM fiber can be selected to meet different applications. We can also offer different product packages, including metal box and 19” 1U rackmount.
