There are supposed to be Multimode-purpose SFP BiDi available

BERT generated a 1G Ethernet Signal, the BIDI transceiver coupled it to multimode link  with 1310nm and carried it to the other SFP BiDi . Then, the incoming signal inside the flexBox loop was sent to the transmitter of the same BIDI and in turn, was sent through the same fibres with 1550nm back to BERT.  This allowed us to analyse if the sent Bit Pattern corresponded to that of the received one.  This worked well up to a distance of 320m.  Over larger distances we ended up with bit failure rates.During Nov., 2010, any Shenzhen Sopto Systems Co.,http://www.fiberyes.com/sfp-bidi Ltd. from a technical perspective revealed during 10. 3125G together with 9. 953G SFP BiDi optical transceiver module meant for 10GBASE-BX, together with complies when using the IEEE 802. 3ae world principles. Any SFP BiDi optical transceiver module help support several numerous Loopback form: SFP BiDi optical transceiver module loopback form together with path loopback, giving you more effective provider together with help support to your product registers.

SFP (small form-factor pluggable) is a compact, hot-pluggable transceiver used for both telecommunication and data communication applications. It interfaces a network device mother board to a fiber optic orcopper networking cable. It is a popular industry format jointly developed and supported by many network component vendors. SFP transceivers are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards.Fiberstore supply various kinds of SFP module such as DWDM SFP,SFP BiDi.
