BIDI is belong single-fiber bidirectional transceiver, only has 1 port, filtering through the filter in the optical transceiver, and finish the emission by 1310nm and reception by 1550nm at the same time, or on the contrary. So this kind of module must be used in pairs. Its biggest advantage is to save fiber resources. The common wavelength of BIDI optical transceiver are TX1310 / RX1550nm; TX1310 /RX 1490nm; TX1550 / RX1490nm.

SFP+ optical transceiver, (10 Gigabit Small Form Factor Pluggable) is a hot pluggable optical transceiver independent of communication protocol, the usual wavelength are 850nm, 1310nm or 1550nm. Used for 10G bps SONET/SDH, fiber channel, gigabit Ethernet, 10 gigabit Ethernet and other applications, also includes DWDM link.

Therefore, BiDi SFP+ optical transceiver is developed and designed based on the CPRI and OBSAI standard. BiDi SFP+ optical transceiver uses SFP+ small package, meet SFF- 8431 MSA, SFF-8432 and SFF -8472 and other protocol standards. Supports bidirectional transmission. Also supports different transmission distances, including 10km, 20km and 40 km etc. In addition, its operating temperature range is very wide, can be easily operated from 0℃ to 75℃, becomes the first choice for both indoor and outdoor communication networks, provides high-speed and stable signal transmission channel.
The advantages of BiDi SFP+ optical transceiver:
※ The transmission distance of TX1270/RX1330nm is 10KM / 20KM / 40KM / 60KM; TX1490/RX1550nm is 80KM
※ Single power +3.3V power supply
※ LVPECL/PECL data interface
※ Working temperature: 0℃-70℃
※ Meet the requirement of GR-468-CORE
