Where a conventional 40GBASE-SR4 module needs eight fibers and MPO\/MTP cabling, the BiDi module transmits and receives simultaneously on two wavelengths (nominal 850 nm and 900 nm), so operators can reuse the two-strand OM3\/OM4 duplex cabling already in place for 10G and move to 40G without re-running fiber. It presents a 4 × 10.3125 Gbps electrical interface (40GbE XLPPI, IEEE 802.3ba), reaches 100 m over OM3 and 150 m over OM4\/OM5 multimode fiber, and supports digital optical monitoring (DOM). Typical use is 40G leaf-spine uplinks and aggregation on Cisco QSFP+ ports in data-center and enterprise networks.\u003c\/p\u003e\u003cp\u003eThis listing is for a new, genuine Cisco-branded QSFP-40G-SR-BD module with a duplex LC optical interface, sold as a single transceiver with multiple units in stock. Fiber patch cabling is not included.\u003c\/p\u003e\u003cp\u003eThis unit is new, as listed.
