SFP to ethernet converter 1.25G DWDM 80km 50GHz
General Description
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. 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.

FAQ
1、Question：What is your lead time for sampling?
Answer：It is about 1-3 working days after payment received.
2、Question：What is your minimum order?
Answer：To achieve customers' satisfaction, we accept sample order, even one piece.
3、Question： What cable type is needed for this transceiver?
Answer：The 1250Mb/s SFP DWDM 80km transceivers use single mode fiber patch cables with duplex LC/UPC connectors.
4、Question：What are the differences between MTP/MPO interface and LC interface 40G QSFP+ transceivers?
Answer：On one hand, the HTF 40G QSFP+ transceivers with LC interface are used for long-distance transmission over single mode fiber, and those with MTP/MPO interface are utilized for short distance transmission over multimode fiber. On the other hand, for the HTF 40G QSFP+ transceivers with LC interface, they cannot be split into 4x10G as they use 4 wavelengths on a pair of single-mode fibers and do not lend themselves to “splitting” into 4 pairs without substantial complexity to split out the wavelengths. For the HTF 40G QSFP+ transceivers with MTP/MPO interface, they can be used in 4x10G connectivity via an external 12-fiber parallel to 2-fiber duplex breakout cable, which connects the 40G transceiver to four 10G optical interfaces.
