The LS-DW3610-80I is specifically engineered with an integrated TEC (thermoelectric cooler) on the EML transmitter and tested in thermal chambers from -40°C to +85°C, preventing wavelength drift across adjacent 100GHz ITU channels in unheated outdoor cabinets and 5G base stations. by LINK-PP Technical Support
Yes. The LINK-PP LS-DW3610-80I operates on the standard 100GHz ITU-T Grid Channel C36 (1548.51nm) and supports 10GBASE-ZR/ZW and SDH STM-64 (10.7Gbps). Just specify Extreme or Arista compatibility when ordering—we program the EEPROM to match each host platform with full SFF-8472 DOM/DDM telemetry. by LINK-PP Technical Support
Use standard OS2 (9/125µm G.652.D) single-mode fiber with Duplex LC/UPC connectors. Since the cooled EML transmits at -1 to +5dBm and the APD receiver overload is -6dBm (sensitivity -23dBm), install a 10dB–15dB LC attenuator for short spans or back-to-back lab testing so RX power stays safely between -10dBm and -20dBm. by LINK-PP Technical Support
The LS-DW3610-80I complies with SFF-8431, SFF-8472 (DDM/DOM), IEEE 802.3ae 10GBASE-ZR/ZW, ITU-T G.694.1 100GHz DWDM grid (C36 1548.51nm), and SONET OC-192 / SDH STM-64, as well as RoHS, CE, FCC, and Class 1 laser safety standards. by LINK-PP Technical Support
