General Description
HTF’HTSF-C1MxxXx Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA), The optical output can be disabled by a TTL logic high-level input of Tx Disable, and the system also can disable the module via I2C.
Mechanical Dimensions
What are the main packaging methods and types of CWDM optical modules?
The CWDM optical module package is available in three types: SFP, SFP, and XFP optical modules. The transmission distances are generally as follows: 40KM, 80KM, 100KM, and 120KM.
CWDM optical modules can be classified into CWDM SFP optical modules, CWDM GBIC optical modules, CWDM SFP optical modules, CWDM XFP optical modules, CWDM X2 optical modules, CWDMXENPAK optical modules, and CWDM LX-4 optical modules.
FAQ
1、Question: Just making sure, I can plug an LC fiber connector into these correct?
Answer: Yep, these are LC. Make sure you are using MMF, not SMF for the -SR part number.
2、Question: Will this works with single mode or multi-mode or both?
Answer: No, it only works with single mode and the wavelength confirms that.
3、Question：Which would I choose, SFP+ or 10GBase-T？Why?
Answer：SFP+ is the most cost effective, dedicated fiber is the best for air flow in the DC, RJ45 is cheap but bulky.
