· Mobile fronthaul and backhaul

· DWDM sparing

 

The tunable small form-factor pluggable (SFP) transceiver is based on Lightip’s patented proprietary technology, the half-wave coupled V-cavity laser (VCL). With the advantages of compactness, fabrication simplicity and easy wavelength control of VCL, this tunable transceiver offers a cost-effective solution for tunable applications in access, mobile fronthaul and backhaul, data center and metropolitan DWDM networks. In addition, it has now incorporated the port agnostic feature with message channel via low-frequency envelope modulation, compliant to ITU-T G.698.4 (G.metro) standard. It enables the tunable SFP module to automatically adapt its DWDM channel frequency, thus reducing the installation and maintenance cost.

The TSFP10D series single mode tunable SFP transceiver is hot-pluggable 20-pin duplex SFP module compliant with SFF-8472 MSA. It is based on Lightips TLD-BD series tunable XMD TOSA, co-packaged with an APD ROSA, and an SFP MSA compatible interface. The optical interface is duplex LC connector. It supports 10Gbps data rates with a typical fiber coupled output power of 6dBm, and can provide 16-32 channels at 100GHz spacing or 32-64 channels at 50GHz spacing in C- or L- band with a customer specified starting wavelength. The transceiver module can be operated under ambient operating temperature between 0 and 70.
