Q
What data rate does the ONS-SI-2G-L1-C module support?
A
This SFP module supports a 2.488 Gbps data rate, meeting OC48/STM16 specifications for high-speed optical networks.
Q
What is the maximum transmission distance for the LR1 1310nm ITEMP SFP?
A
Over single-mode fiber, the ONS-SI-2G-L1-C delivers up to 10 km reach at 1310 nm under industrial temperature conditions.
Q
What wavelength does the ONS-SI-2G-L1-C operate on?
A
This OC48/STM16 LR1 SFP operates at a nominal wavelength of 1310 nm for long-reach applications.
Q
What temperature range does the ITEMP version support?
