It is the B-end module of Omada's 10GBase-BX pairing, intended for 10 km single-mode runs where fibre count, not distance, is the constraint.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eHalve your fibre count on every 10G run\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eConventional 10G optics burn two strands per link, one for each direction. The SM5110LSB-10 uses wavelength-division multiplexing to put both directions on a single strand of 9\/125 um single-mode fibre, transmitting at 1270 nm and receiving at 1330 nm through one simplex LC\/UPC connector. On a campus or inter-building route where you are paying per strand, or working with a duct that is already full, that turns a link you cannot build into one you can. It also frees existing dark fibre for other services without trenching or re-splicing.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eFull 10.3125 Gbps line rate out to 10 km\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThis is a full-rate 10 Gigabit module, not a throttled one: 10.3125 Gbps to IEEE 802.3ae and the 10GBase-BR specification, with a rated reach of 10 km over single-mode fibre. A DFB laser transmits between -8.2 and 0.5 dBm with an extinction ratio above 3.5 dB, and the PIN-TIA receiver is sensitive below -14.4 dBm with an overload point above 0.5 dBm. That gives roughly 14 dB of optical margin to absorb splice, patch-panel and connector losses across a real-world route.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eSee the link health before it fails\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe module implements Digital Diagnostic Monitoring to SFF-8472, so the host switch can read live module temperature, supply voltage, laser bias current and both transmit and receive optical power. On a 10 km single-fibre span those readings are the difference between guessing and knowing: a receive power figure drifting toward the -14.4 dBm sensitivity threshold flags a dirty connector or a degrading splice while the link is still passing traffic, rather than after an outage. It also makes commissioning straightforward, since you can verify budget on day one.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eDrops straight into Omada 10G SFP+ slots\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe SM5110LSB-10 is built to the SFP+ multi-source agreement and complies with SFF-8431, SFF-8432 and SFF-8472, so it seats in a standard 10G SFP+ cage and is hot-swappable with the switch live. It runs from the 3.3 V rail at no more than 1 W, and measures 57 x 14 x 12 mm. TP-Link lists compatibility with Omada switches carrying 10G ports such as the SG3428X and SG3452X. Operating range is 0 to 70 degrees C, with CE, FCC and RoHS compliance.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eOrder it as a pair, not on its own\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eBiDi optics only work in matched pairs with opposed wavelengths, and this is the B end. Its 1270 nm transmit must meet the 1270 nm receive of an SM5110LSA-10 at the far end, and vice versa at 1330 nm. Two B-end modules facing each other will not link, because both would transmit on the same wavelength. For each single-fibre 10G span, buy one SM5110LSB-10 and one SM5110LSA-10, and label which end of the run takes which so future maintenance does not swap them.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eIdeal For\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eSingapore businesses, schools, hotels and managed-service providers building on Omada, and IT teams that want a accessory they can adopt, monitor and update centrally rather than box by box.
