25G Tunable DWDM SFP28 C-band 48 channels 15km Optical Transceiver Module


25G DWDM Tunable SFP28 C-band 48 channels 15km Optical Transceiver Module

The MSA Compatible 25G DWDM Tunable SFP28 (Small Form-Factor Pluggable 28) multi-rate (9.83-25.78 Gbps) transceiver is designed for operation over duplex Single-Mode Fiber (SMF) optical cable in 5G Mobile Fronthaul environments for interconnection of radio heads and baseband units. On the transmission side 25G DWDM 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.

This 25G DWDM 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 DWDM 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. 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).
