You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).

Cisco GLC-LH-SMD 1000BASE-LX/LH SFP 適用於多模和單模光纖。
1000BASE-LX/LH SFP 與 IEEE 802.3z 1000BASE-LX 標準相容,可在長達 10 km 的標準單模光纖鏈路跨度上運行,在任何多模光纖上可長達 550 m。當在傳統多模光纖類型上使用時,發射器應透過模式調節跳線進行耦合。 1300 nm 波長、擴展的工作溫度範圍和 DOM 支援、雙 LC/PC 連接器。

筆記:
*無論跨距長度為何,都需要 IEEE 標準指定的模式調整跳線。請注意 62.5 μm 光纖的模式調節跳線與 50 μm 光纖的模式調節跳線有不同的規格。
** IEEE 802.3z 標準指定的 ITU-T G.652 SMF。
***指定傳輸波長。
