NADDOD 100G Optical Transceiver Enables New Infrastructure for 5G and Data Centers

In 5G network deployment, operators need to place wider bandwidth for the use of high traffic data, such as long distance medical transport, VR, 4K/8K video, etc. Therefore, mobile networks must have higher rates at all levels, which also drives the development of 25G optical transceivers/100G optical transceivers.

In addition to the huge demand for optical transceivers in carrier networks, the accelerated construction of cloud computing data centers has raised the demand for 25G optical transceivers/100G optical transceivers. Therefore, the demand for 100G optical transceivers brought by the new construction and transformation of global data center networks will be planned to be released, and the high-speed optical transceiver market will maintain a high boom.

As a leading supplier of optical network solutions, NADDOD provides operators and data centers with high-quality, cost-effective 100G optical transceiver solutions to fully meet the optical network needs of different scenarios and enable 5G and data center new infrastructure.

100G Short-range Transmission: QSFP28 SR4 (100m)

100G QSFP28 SR4 is specifically designed for short-range transmission in 100G Ethernet and provides four independent transmit and receive channels, each operating at 25Gbps. 100G QSFP28 SR4 optical transceivers feature an MTP interface and have a transmission distance of 70m when used with OM3 multimode fiber and 100m when used with OM4 multimode fiber.

NADDOD 100G QSFP28 SR4 optical transceivers are mainly used for data center 100G direct connection and 25G-100G network upgrade. 100G direct connection only requires inserting two 100G QSFP28 SR4 optical transceivers into the corresponding ports of two 100G switches, and then connecting the two transceivers using OM3 or OM4 multimode fiber patch cables.

For 25G-100G network upgrade, simply plug one QSFP28 SR4 optical transceiver and four 25G SFP28 SR optical transceivers into the 100G and 25G switch ports, respectively, and connect them with MTP branch patch cables.

100G Medium-range Transmission: QSFP28 PSM4, CWDM4 (2km)

NADDOD 100G QSFP28 PSM4 and 100G QSFP28 CWDM4 both have transmission distance up to 2km. 100G QSFP28 PSM4 adopts parallel transmission technology, transmitting four identical wavelengths with four independent single-mode fibers. 100G QSFP28 CWDM4 adopts coarse wavelength division multiplexing technology, transmitting through one transceiver and one transmitter with two single-mode fibers, effectively reducing fiber resources cost in medium and long distance.

NADDOD 100G QSFP28 PSM4 is used for 100G-100G and 25G-100G interconnections. The former only requires two 100G QSFP28 PSM4 optical transceivers to be plugged into the corresponding 100G switch and connected with MTP single-mode fiber patch cables; while the latter requires one QSFP28 PSM4 optical transceiver and four 25G SFP28 LR optical transceivers to be plugged into the corresponding 100G and 25G The latter requires one QSFP28 PSM4 optical transceiver and four 25G SFP28 LR optical transceivers to be inserted into the corresponding 100G and 25G switches, and then connected with MTP/MPO to LC single-mode fiber patch cables to complete the 25G-100G interconnection.

NADDOD 100G QSFP28 CWDM4 is commonly used for 100G-100G interconnection, just plug two 100G QSFP28 CWDM4 optical transceivers into the corresponding ports of two 100G switches, and then use LC duplex single-mode fiber patch cable to achieve 100G interconnection.

100G Medium to Long Range Transmission: QSFP28 LR4/LR single channel (10km)

100G QSFP28 LR4 is used for 100G Ethernet long-distance transmission and can be used with single-mode fiber optic patch cables up to 10km. 100G QSFP28 LR4 direct connection solution is very simple, just insert two 100G QSFP28 LR4 optical transceivers into the corresponding 100G switch ports and connect the two transceivers with an LC single-mode duplex fiber patch cable.



In addition to the QSFP28 LR4, NADDOD can also provide QSFP28 LR single-channel 100G optical transceivers with transmission distances up to 10km, connected in the same way as the QSFP28 LR4.

100G Long Range Transmission: QSFP28 ER4 (40km)

NADDOD 100G QSFP28 ER4 optical transceiver can transmit up to 40km on single-mode fiber. 100G QSFP28 ER4 optical transceiver transmitter works on four LAN WDM wavelength bands of 1295nm, 1300nm, 1305nm and 1310nm, the optical signals on these four bands are multiplexed by WDM wavelength division multiplexer and then transmitted through LC duplex single-mode fiber patch cable. At the receiving end, the optical signal is first amplified by the SOA (PIN receiver is used to convert the optical signal back to electrical signal), and then the signal is broken down into individual channels by the WDM multiplexer.



NADDOD 100G QSFP28 ER4 can be used for 100G direct connection, just insert two 100G QSFP28 ER4 optical transceivers into the QSFP28 ports of two 100G switches and connect them with an LC duplex single-mode fiber patch cable to achieve 100G direct connection with a maximum transmission distance of 40km.
