This BiDirectional (BDSR) optical module transmits 40Gbps over a single pair of standard multimode fiber via a Duplex LC interface. Eliminating the need for expensive MPO cable upgrades, it provides an instant, plug-and-play 10G-to-40G migration path for distances up to 100m or 150m. Cisco® QSFP-DD and OSFP 800G ZR/ZR+ coherent optics modules enable 800G traffic over. QSFP-DD pricing creates significant challenges for buyers due to the extreme opacity of the market. Standard procurement guides list endless catalog numbers without valuable context, overwhelming engineers with technical specifications while completely obscuring actual market costs. OEM SFP modules are small form-factor pluggable (SFP) optical transceivers that are manufactured by original optical component suppliers but sold under the branding and part numbers of major networking equipment vendors such as Cisco, Arista, or Juniper.
