Product details
Overview
The FT-SFPPLUS-1-25G-3 is the F-tone Networks 1.25 Gbps DWDM SFP+ transceiver family, with reach options of 40 km, 80 km and 120 km. All variants use DFB lasers for the tight wavelength stability that dense WDM multiplexing requires; the 120 km variant adds an APD receiver for extra receive sensitivity on the longest spans. Commercial (0 to 70 C) and industrial (-40 to 85 C) temperature grades are available. Dense wavelength division multiplexing packs many more channels onto a single fiber pair than CWDM, making this family suited to capacity-constrained metro and long-haul routes where fiber is scarce.
Key Features
- 1.25 Gbps DWDM SFP+ family, 40/80/120 km reach options
- DFB lasers for DWDM wavelength stability
- PIN receivers on 40/80 km; APD receiver on 120 km
- Commercial 0 to 70 C and industrial -40 to 85 C temperature grades
- Dense channel packing on single fiber pairs via DWDM
Applications
- DWDM metro and long-haul transport networks
- Carrier wavelength services and leased-line capacity
- Fiber-exhaust routes needing maximum channel density
