Isi mmalite nke modul anya
Ngwa anya ihe mejupụtara ngwaọrụ optoelectronic, sekit arụ ọrụ na oghere anya. Ngwa optoelectronic gụnyere akụkụ abụọ: nnyefe na ịnata. Na nkenke, ọrụ nke modul optical bụ ịgbanwe akara ngosi eletrik n'ime akara ngosi na njedebe izipu. Mgbe ebufechara mgbama ngwa anya site na eriri anya, njedebe nnata na-atụgharị akara ngosi n'ime akara ọkụ eletrik.
Akụkụ nke mbufe bụ: mgbama mgbanaka eletrịkị ntinye nke ụfọdụ ọnụego ka a na-ahazi ya site na mgbawa nke ime, wee chụpụ semiconductor laser (LD) ma ọ bụ ọkụ na-emitting diode (LED) ka ọ wepụta akara ngosi anya modulated nke ọnụego kwekọrọ. Emebere sekit njikwa anya akpaka nke ime ime ka ike mgbama ngwa anya pụta kwụsie ike.
Akụkụ na-anata bụ: modul ntinye mgbama ngwa anya nwere ntakịrị ntakịrị ntakịrị ka a na-atụgharị n'ime mgbama eletrik site na diode nchọpụta anya, na mgbama ọkụ eletrik na ọnụọgụ ọnụọgụ kwekọrọ na-apụta mgbe preamplifier.
-Basic echiche nke ngwa anya modul-
Port-optical modul bụ aha izugbe nke ụdị modul dị iche iche, na-ezo aka na modul transceiver agbakwunyere ngwa anya
- Ọrụ nke modul optical-
Ọrụ ya bụ naanị ịghọta ngbanwe n'etiti akara anya na akara eletrik.
-Optical modul Ọdịdị-
Modul anya na-ejikarị transmitter anya, ihe nnata anya, sekit na-arụ ọrụ na ngwa anya (eletrik).
N'ebe onye na-ebufe ya, onye na-anya ụgbọ ala na-arụzi mgbama ọkụ eletrik mbụ, wee chụpụ semiconductor laser (LD) ma ọ bụ ọkụ na-emitting diode (LED) ka ọ na-ebunye mgbama ngwa anya modulated.
Ọdụ ụgbọ mmiri dị na njedebe nnabata. Mgbe mgbama ngwa anya batara, a na-atụgharị ya na mgbama eletrik site na diode nchọpụta anya, wee wepụta akara eletrik site na preamplifier.

Emebere CFP na ndabere nke interface SFP, yana nnukwu nha yana ịkwado nnyefe data 100Gbps. CFP nwere ike ịkwado otu mgbaàmà 100G yana otu ma ọ bụ karịa 40G.
Ihe dị iche n'etiti CFP, CFP2 na CFP4 bụ olu. Olu CFP2 bụ ọkara nke CFP, na CFP4 bụ otu ụzọ n'ụzọ anọ nke CFP. CFP8 bụ ụdị nkwakọ ngwaahịa akwadoro maka 400G, na nha ya dabara na CFP2. Na-akwado 25Gbps na 50Gbps ọwa ọnụego, na-aghọta 400Gbps modul ọnụego site 16x25G ma ọ bụ 8 × 50 eletrọn interface.
