MikroTik S+2733LC10D SFP+ BiDi Pair 10G Single-Mode

10G fibre links where the number of available strands is limited require a solution that carries traffic in both directions over a single fibre. A pair of single-mode BiDi SFP+ modules that transmit and receive on different wavelengths addresses this need and halves fibre usage on routes of up to 10 km. S+2733LC10D delivers long-distance 10G connectivity and suits networks that need fast uplinks over a single fibre without laying additional fibre.

The pair operates at 10G over single-mode fibre, transmitting on 1270 nm at one end and 1330 nm at the other over a single strand. Built-in digital diagnostics (DDM) monitor optical power, voltage, temperature, and laser bias current, flagging abnormal activity or breaches of configured operating limits. This data supports maintenance and upgrade planning based on real performance, reducing the risk of disruption on critical links.

The standard SFP+ form factor and single-fibre bi-directional LC connector ensure compatibility with switches and routers that support 10G BiDi optics at 10 km. The modules must be used as a matched pair (the 1270 nm end with the 1330 nm end) and provide an affordable alternative to the XS+2733LC15D pair for infrastructures that do not need 25G SFP28. They fit into 10G backbone links, site-to-site interconnects, and long-range single-fibre uplinks.

The pair is aimed at system integrators, infrastructure engineers, and IT teams operating enterprise networks, industrial deployments, and ISP nodes with limited fibre resources. It suits interconnecting buildings across a campus, metropolitan 10G single-fibre links, and aggregation uplinks at ISP points of presence. DDM support makes it suitable for backbone links, where proactive monitoring of optical parameters reduces diagnostic time and allows interventions to be scheduled before the link degrades.
