DWDM-25GFH-S28-15I-TUN

    DWDM-25GFH-S28-15I-TUN is Multi-Vendor MSA Compatible 25G SFP28 (Small Form-Factor Pluggable 28) DWDM Tunable multi-rate (9.83-25.78 Gbps) transceiver designed for operation over Double Single-Mode Fiber (SMF) optical cable in 5G Mobile Fronthaul environments for interconnection of radio heads and baseband units. Module has a guaranteed optical budget of 19.5 dB, which in most cases is enough to reach up to 15 kilometer distance with FEC (Forward Error Correction) present on the host device. Distance is just an indicative parameter for comfort of identification that is calculated by taking into account minimal optical budget and average attenuation of optical cabling in industry. On the transmission side 25G SFP28 DWDM 100GHZ C-Band Tunable module converts a 25-Gbps NRZ electrical signal into a 25-Gbps optical signal on a specific wavelength and reversely at the receiver side 25-Gbps optical signal is converted into 25-Gbps NRZ electrical signal. DWDM-25GFH-S28-15I-TUN SFP28 transceiver has a tunable laser with 48 channel support from the ITU-T 100GHz DWDM Channel Grid, more specifically Channel 13 to Channel 60 (191.3~196.0 THz) are supported. Transceivers support Wavelength auto-tuning (auto negotiation) functionality, where transceivers at both sides of the link can automatically match the link wavelength in the WDM system. Manual operation of wavelength tuning can be performed according to SFF-8690 Rev1.4 specification Page 6 description. One of 25G tunable SFP28 modules’ advantages is to reduce the extensive backup module amount in dense DWDM network environments with many hops and dedicated DWDM channels for each link.

    25G SFP28 DWDM 100GHZ C-Band Tunable module has DDM/DOM optical diagnostics functionality, which provides real time access to device operating parameters, control and status registers as specified in SFF-8472. DWDM-25GFH-S28-15I-TUN operates in -20° to 80°C temperature range and has a Double LC interface. This SFP28 supports 9.8-25.78 Gbps data rate and such applications as CPRI option 10 (24.33 Gbps), CPRI option 7 (9.830 Gbps), CPRI option 8 (10.138 Gbps), CPRI option 9 (12.165 Gbps).

    25G SFP28 DWDM 100GHZ C-Band Tunable transceiver is CE/RoHS certified and it is Compliant with product safety standards. DWDM-25GFH-S28-15I-TUN SFP28 Transceiver is fully compliant to SFP28 Multi Source Agreement, IEEE802.3cc (25 Gb/s Ethernet over Single-Mode Fiber), SFF-8472 and SFF-8690. Consequently, it means that module is compatible with 80% of networking equipment, where is not implemented a special algorithm for protection against third party modules. However – we can provide an SFP28 transceiver with custom-encoded firmware in order to make it work in almost any base station manufacturers equipment. Therefore, we will be glad to know your requirements.
