NOTES

1. For full compliance with OC-3/STM-1 Intermediate Reach/S-1.1 standard, the STX-03-YYY-T-L3 modules are recommended.

2. For full compliance with OC-3/STM-1 Long Reach 1310 nm/L-1.1 standard, the STX-03-YYY-A-L0-LR1 & STX-03-YYY-B-

L0-LR1 are recommended. The STX-01-YYY-A-L0-LR1 uses a DFB laser to satisfy the Center Wavelength requirement.

3. For full compliance with OC-3/STM-1 Long Reach 1550 nm/L-1.2 standard, the STX-03-YYY-A-L0-LR2 & STX-03-YYY-B-

L0-LR2 are recommended. Both modules use DFB lasers. However, the STX-03-YYY-A-L0-LR2 module is specified only over

- 25°C to +70°C temperature range. Please consult OCP Sales for the - 40°C to +70°C pigtailed option.

4. The LR1 (-40°C to +85°C) and LR2 options are only available with DFB lasers and L0 or HP optical power levels.
