NOTES
1. For full compliance with OC-1 Intermediate Reach standard, the STX-01-YYY-A-L3 & STX-01-YYY-B-L3 are recommended.
2. For full compliance with OC-1 Long Reach 1310 nm standard, the STX-01-YYY-A-L0-LR1 & STX-01-YYY-B-L0-LR1 are
recommended. The STX-01-YYY-A-L0-LR1 uses a DFB laser to satisfy the - 40°C to +85°C requirement for Center Wavelength.
3. For full compliance with OC-1 Long Reach 1550 nm standard, the STX-01-YYY-A-L0-LR2 & STX-01-YYY-B-L0-LR2 are
recommended. Both modules use DFB lasers.
However, the STX-01-YYY-A-L0-LR2 module is specified only over - 25°C to +70°C temperature range.
4. The LR1 (-40°C to +85°C) and LR2 options are only available with DFB lasers and L0 or HP optical power levels.
