DWDM-100G-Q28-120-XX

100G DWDM transceiver DWDM-100G-Q28-120 is a Multi-Vendor MSA Compatible Single- wavelength 100G DWDM QSFP28 Transceiver (Quad Small Form-Factor Pluggable 28) Transceiver designed for multiple channel 100G transmission over G.652 Single-Mode Fiber (SMF). Efficient multiple 100G Ethernet signal transmission over double or single fiber is a milestone in the optical communication industry and helps Data Centers, Mobile Operators and Fixed Operators to migrate legacy 10G DWDM/CWDM connections to high speed 100G DWDM optics connections.

100G DWDM QSFP28 transceiver DWDM-100G-Q28-120 has a minimum guaranteed optical budget of 7 dB, which in most cases is enough to reach 2 km distance without DCM (Dispersion Compensation Module) and EDFA (Erbium-Doped Fiber Amplifier), however for long and extended reach applications up to 120km EDFA and DCM are required to compensate the fiber link loss and fiber dispersion. With help of EDFA and DCM 25dB link budget can be achieved and up to 120km reach can be fulfilled considering near ideal conditions with fiber loss 0.2dB/km (or 24dB total) and with 1dB safety margin. We have summarized typical applications for DWDM-100G-Q28-120 transceivers and are able to offer complete solutions including DWDM filters, EDFA Boosters and DCM units, for more details – Contact Us. 100G DWDM QSFP28 transceivers support standard 40 DWDM channels (ITU-T 100GHz DWDM grid) which are compatible with standard Double Fiber DWDM or Single Fiber DWDM 100GHz filters. Supported channels are starting from Channel 21 (1560.61 nm) up to Channel 60 (1529.55 nm). Additional channels are available upon request and can be offered as customized products. The 100G DWDM QSFP28 module supports DDM/DOM optical diagnostics, which provide diagnostic information about the present operating conditions. The 100G DWDM optics transceiver operates in the standard 0°-70°C temperature range and has a duplex LC optical connector and on the electrical side supports 4×25.78 Gbps CAUI-4 host interface which is compatible with standard 100G Ethernet switches. 100G DWDM Transceiver has integrated QSFP28 PAM4 (Pulse Amplitude Modulation 4-level) DSP (Digital Signal Processor) chip and module uses a PAM4 gearbox to convert the 4×25.78 Gbps CAUI-4 electrical signals to a single lane PAM4 100G optical signal. Transceiver uses DFB (Distributed Feedback Laser), Silicon Photonics external modulator and receiver use wideband PIN-Photodiode and is DWDM channel independent. The 100G DWDM QSFP28 module preferably should be used in high power QSFP28 switch/router ports (Power Class 7, 5W). Module has an integrated FEC, while FEC on the host platform needs to be disabled.

100G DWDM transceivers DWDM-100G-Q28-120 are certified and are compliant with product safety standards. Transceivers are fully compliant to QSFP28 Multi Source Agreement SFF-8636, QSFP28 MSA digital monitoring functions and are Laser Class 1 compliant according to International Safety Standard IEC-60825. Consequently, compliance to above standards guarantees that module is compatible and works with majority of networking equipment, where is not implemented special algorithm for protection against third party modules.

The 100G DWDM transceivers can be used in Cisco, Juniper, Nokia, HP, Huawei and other manufacturers equipment which have 100G QSFP28 port capabilities. So far originally almost none of these manufacturers have 100G DWDM QSFP28 transceivers in their portfolio, however we have accumulated deep expertise in custom-encoded firmware for 100G DWDM QSFP28 in order to make these modules work in almost any brand of equipment.
