General Description
HTF’HTSF-C1MxxYx Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). Tx Fault is provided to indicate that degradation of the laser. Loss of signal (LOS) output is provided to indicate the loss of an input optical signal of receiver or the link status with partner. The system can also get the LOS (or Link)/Disable/Fault information via I2C register access.
Mechanical Dimensions
What is the difference between a CWDM optical module and a normal optical module?
The CWDM optical module is a passive module that does not emit laser light itself. Generally, optical planar waveguide (PLC) technology is used, which simply divides a beam of light into several beams of light. The ordinary optical module belongs to the photoelectric conversion device and is an active optical module. Each module has one receiving and two ports, and the inside of the transmitting port is a laser.
FAQ
1、Question：What are CWDM, DWDM, SFP and GBIC used for? What kind of company buys them?
Answer：These are optical fiber transceivers designed to be used with passive optical multiplexers. If you have a number of these all transmitting on different wavelengths, you can use a passive multiplexer to combine each signal onto a single fiber pair, and then de-multiplex the signal at the far end. Unlike active systems, a passive multiplexer requires no power or management - it's literally a set of waveguides and prisms in a rack mount chassis - which greatly reduces the cost of doing WDM and eliminates a potential point of failure in the system.
2、Question：What is the best method to make fiber runs with SFP connectors 100M+?
Answer：Making fiber runs with SFP and distance over 100m is easy to reach. Both single-mode SFP and multi-mode SFP transceivers can meet the requirement. It's all depends on your actual need.
3、Question：What's HTSF-C1MxxYx transceiver max supported distance?
Answer：The transceiver supports up to 160km over single mode fibers.
