DWDM-SFP-37.40 — 1537.40 nm — SFP 1 Gbps

Operating at a DWDM wavelength of 1537.40 nm, the Cisco DWDM-SFP-37.40 is a 1 Gbps SFP module for single-mode fiber supporting links of up to 80 km. An LC (UPC) duplex connector, IEEE 1000BASE-X compliance, and a thermal range of 0 to 70 degrees C make it a professional-grade transceiver for high-density DWDM infrastructures.

Designed to slot into carrier or enterprise campus DWDM multiplexers, it routes a Gigabit stream over a precise channel at 1537.40 nm, coexisting with many other channels on the same fiber strand. The ideal choice for capacity expansion without new cabling. Genuine Cisco hardware, manufacturer warranty.
