Ordering Info
If there are no special requirements, the fiber interface of the SPD6522Q device is G657A2 single-mode fiber (0.9mm tight-buffered protective tube), FC/UPC connector, and fiber length 1.0m, that is, the detailed order model is SPD6522Q.
If the fiber specifications, length, connector, etc. required for the ordered product are inconsistent with this product, please follow the following format:
Note:
● The product is an electrostatic sensitive device, and ESD protection must be taken during storage and use.
● The bending radius of the product fiber is not less than 30mm. Avoid fiber breakage and contamination or damage to the connector during storage and use.
● The product requires external refrigeration. The clamping carrier used for refrigeration needs to be made of a material with good thermal conductivity, keep the cavity wall at one end of the device lead and the contact surface of the clamping carrier tightly matched, and apply thermal conductive material on the contact surface of the two.
● The product should be stored in a clean environment with ventilation and no corrosive gas at a temperature of -10~+40℃ and a relative humidity of no more than 80%.
