What is the L band DWDM?

WDM technology can be divided into WDM, CWDM, and DWDM according to different wavelength modes. The wavelength range defined by ITU-T, The CWDM range is 1271 to 1611nm based on ITU-T G 684.2. Considering the fiber attenuation of the 1270-1470nm band in the application, the band of 1470~1610nm is usually used. The channel space of […]


What is the different between LSH Cable and LSZH Cable

LSF Cable (Low Smoke & Fume Cable) LSF cable is different than LSZH Cable, it is made up of a modified PVC compound and produces HCL gas and black smoke when burning, but about 80% less than PVC cable. Some points to remember about these cables are: These cables are often purchased to cut costs […]


4-Rule for using Standard MPO Patch Cord, MPO Connector and MPO Adaptor

Rule-1: When mating two MPO patch cords, it shall be an MPO male connector and an MPO female connector. Rule-2: For the standard MPO Connectors, changing the polarity, or adding or removing the guiding pins in the field is not allowed. Rule-3: MPO Female connector for direct connection to the optical module if it is […]

Applications of MCF (Multicore Fiber)

Multicore fiber consists of several optical fibers, which are buffered inside a single jacket. Multicore fiber can also be arranged and consolidated inside of a further jacketing. This arrangement of fiber can be referred to as space鈥揹ivision multiplexing since the buffered optical fibers are spatially separated while arranged within a single jacket. Applications for MCF […]

Which 40G MMF duplex transceiver should I choose, QSFP-40G-SRBD or QSFP-40G-SWDM4?

TARLUZ currently offers two 40G transceivers that operate over duplex multimode fiber, QSFP-40G-SWDM4, and QSFP-40G-SRBD transceivers. Both transceivers operate at multimode fiber and are widely deployed in the industry. QSFP-40G-SWDM4 and QSFP-40G-SRBD are using different technology, so they are not able to use each other. QSFP-40G-SWDM4 Transceiver TARLUZ 40G QSFP+ SWDM4 transceiver provides 40Gbps bandwidth […]
