BFKK 7M OM3 8F Type-B LSZH 50/125µm MPO Fibre Optic Cable Aqua
A 7-metre OM3 multimode patch cord with eight fibres in a Type-B LSZH jacket, rated for 40 G networks with typical insertion loss of 0.3 dB at 850 nm
- Low insertion loss under 0.6 dB at 850 nm
- Typical loss of 0.3 dB ensures efficient signal transmission
- OM3 multimode fibre supports 10G and 40G networks
- LSZH jacket reduces toxic smoke in fire situations
- Type B polarity maps channel 1 to channel 12 for cassette links
7-metre OM3 MPO patch cable
This 7-metre multimode cable uses OM3 50/125 µm fibre with eight cores in a Type-B polarity layout. It is built for 40G network links between MPO or MTP cassettes and QSFP+ transceivers. The aqua LSZH jacket meets low-smoke zero-halogen requirements for indoor routing.
Check connector gender and polarity before ordering
The cable carries female MPO connectors without guide pins on both ends, so the mating equipment must provide pinned male interfaces. Verify that your cassettes or transceivers expect Type-B channel mapping (channel 1 to channel 12) and that the link budget can accommodate the specified insertion loss.
Replaces shorter or lower-grade OM3 jumpers
The jump is worth it when a 7-metre reach is needed without adding intermediate patch panels, or when an existing cable exceeds the 0.6 dB typical insertion loss at 850 nm. It does not suit single-mode runs, male-pinned trunk cables, or networks requiring OM4 or OM5 bandwidth headroom.

Questions about this item
Does the 7 m LSZH cable include both MPO connectors, or do I need to buy them separately?
The cable ships with MPO female connectors on both ends, pinned for Type‑B (channel 1 to 12) wiring, so no separate connectors are required.
When should I choose this 8‑fibre OM3 Type‑B version instead of a 12‑fibre or Type‑A cable?
Pick this 8‑fibre Type‑B assembly when your QSFP+ or cassette ports use an 8‑core MPO interface and need the channel 1‑to‑12 flip for correct polarity.
What does the <0.6 dB insertion loss at 850 nm mean for a 40 G link?
Typical loss is only 0.3 dB per connector, so the total link budget stays well within OM3 40 G limits even with multiple patch panels.
