1.25Gb/s 1310nm Onye na-ebufe SFP otu ụdị

Foto a na-egosi na 1.25Gb/s 1310nm SFP Transceiver nke nwere otu ụdị

Nkọwa Dị Mkpirikpi:

Transceivers Small Form Factor Pluggable (SFP) dakọtara na Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). Transceiver ahụ nwere ngalaba anọ: LD driver, amplifier na-egbochi, FP laser na PIN photo-detector. Data modulu ahụ na-ejikọ ruo 20km na eriri mode otu 9/125um.

Enwere ike gbanyụọ mmepụta anya site na ntinye TTL nke Tx Disable dị elu. E nyere Tx Fault iji gosi mmebi nke laser ahụ. E nyere mfu nke mmepụta mgbaàmà (LOS) iji gosi mfu nke mgbaàmà anya ntinye nke onye nnata ma ọ bụ ọnọdụ njikọ na onye mmekọ.
