SFP BIDI 1.25G 1310/1490nm DDM 20KM Transceiver
SOPTIC’s SFP-DB20-LC13 Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). The SFP transceivers are high performance, cost effective modules supporting Gigabit Ethernet and 20km transmission distance with SMF. They are RoHS compliant and lead-free.
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.

Bidi-sfp: BIDI (Bidirectional). It USES WDM (wavelength division multiplexing) technology to transmit and receive different central wavelengths in two directions, so as to realize bidirectional transmission of optical signals. Generally, optical modules have two ports, such as TX transmitting port and RX receiving port, while BIDI optical module has only one port, which can be filtered through a filter in the optical module to simultaneously transmit 1310nm optical signal and receive 1550nm optical signal, or vice versa. Therefore, BIDI modules must be used in pairs, such as SFP-DB20-LC13 and SFP-DB20-LC15. When SFP-DB20-LC13 is used on one end, the corresponding SFP-DB20-LC15 on the other end. The biggest advantage of the BIDI optical module is to save the optical fiber resources, so that the two transmission fibers are combined.
