1. Why choose to use BIDI SFP?
(1) The BIDI SFP module integrates a duplex data link through a single fiber. It can reduce the cost of fiber cabling infrastructure. As the bundle is cut in half, the number of jumpers and patch panel ports can be reduced accordingly.
(2) Using BIDI SFP modules, it is possible to increase the capacity and reliability by operating at multiple wavelengths simultaneously.
(3) It supports transmission distances up to 120 km.
2. How BIDI SFP connects?
For BIDI SFP, because it uses different wavelengths to transmit and receive signals, (security weak current ring) we should connect two BIDI SFPs with opposite wavelengths together. For example, we use the TX1310/RX1550nm BIDI SFP on one end, then we should use the TX1550/RX1310nm BIDI SFP on the other end.
3. Application of BIDI SFP
BIDI SFP modules are usually applied to high-performance integrated duplex data links through a single fiber. If the transmission distance is within 40km, the wavelength scheme of BIDI SFP modules is 1310nm/1550nm, 1310nm/1490nm. If the transmission distance is above 40km, the wavelength scheme of the BIDI SFP module is 1550 nm/1490 nm.
FAQ
1、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.
