PERFORMANCE EXAMPLES


Ordering information
SLD-35(a)-(b)-(c)-(d)-(e)-XXX,
where:(a) – 0 (free space) or 1 (fiber pigtailed), (b) – power category, HP1, HP2 or HP3,(c) – package type, (d) – SM or PM (for fiber coupled modules), (e) – PD (if PD monitor is required),XXX – wavelength (830, 845, 860; a ±10-nm tolerance is guaranteed). SLD modules with central wavelengths in the range from 825 to 830 nm are available upon request.
Example: SLD-351-HP1-DIL-SM-PD-845.
