available upon request
* It is not allowed to exceed maximum output power or maximum
drive current, whatever happens first
** Center wavelength 670 nm is not guaranteed. Contact Superlum
representative if you require a tighter tolerance of center
wavelength.
*** Rated at minimum power, not guaranteed at maximum power of a
particular power category
**** Pseudo-depolarized versions (light is launched into the fiber at 45
degrees to the birefringent axes) are available upon request
PERFORMANCE EXAMPLES
?All specifications are subject to change without notice ?
Additional & customized:
- FC/APC termination of fiber pigtail
The following part numbers should be used when ordering:
SLD-261-MP(a)-(b)-(c)-PD,
where:
(a) – power category (MP1 or MP2),
(b) – package type (DIL, DBUT, SBUT),
(c) – type of fiber — SM (isotropic) or PM (polarization maintaining).
Example: SLD-261-MP1-DIL-SM-PD.
