Q&A for 100G SFP-DD and 100G DSFP Systems

Q1: What are the SFP-DD and DSFP form factors? A1: The SFP-DD is short for Small Form-factor Pluggable – Double-Density and SFP-DD form-factor is defined by the SFP-DD MSA, while the DSFP is short for Dual Small Form-factor Pluggable and is defined by the DSFP MSA. They are a compact SFP-like form factor with 2x […]

Introduction to O-band WDM

WDM helps the network operators to run several transmission wavelengths on the same pair of optical fiber, it increases the bandwidth capacity among sites. The O-band WDM wavelengths range between 1260nm and 1360nm, compared with C-band featured with lower attenuation, and higher chromatic dispersion, it features a very low chromatic dispersion, but a higher attenuation […]

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 […]

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‚Äďdivision 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 […]
