StarTech.com LOOPBACKLCLC00DB — LC/UPC Single Mode Fiber Loopback, 0 dB

LC/UPC single mode0 dB loopback1,000 test cycles

The StarTech.com LOOPBACKLCLC00DB is an LC/UPC duplex fiber loopback module for single-mode OS1/OS2 (9/125 µm) networks that routes the transmit signal straight back to the receive side of the same port. Technicians use it to verify transceivers, switch ports and patch panels during installation and fault isolation; the low-loss 0 dB design gives a clean baseline, with repeatability within 0.2 dB and return loss above 50 dB.

Compatibility note: Single-mode LC/UPC only — it will not suit multimode (OM3/OM4) or APC-polished ports. Long-reach, high-power optics can overload their own receiver on a 0 dB loop, so check the transceiver receive range and add an attenuator if needed.

Frequently Asked Questions

What does a fiber loopback module test?
It lets a switch, media converter or transceiver receive its own transmitted light, so you can confirm the optic, port and link-up behaviour without a far-end device — useful for commissioning and for isolating whether a fault is in the equipment or the cabling.
Can I use it with multimode SFP+ transceivers?
No. It is built for single-mode 9/125 µm fibre with LC/UPC connectors. Multimode transceivers such as 10GBASE-SR need a multimode loopback module.

Singular Expert Insight

A single-mode LC loopback belongs in every network technician kit: it turns a “no link” call into a quick test of the optic and port before anyone pulls cables. The 0 dB version gives the truest baseline for short and medium reach optics; for long-haul modules use an attenuated loopback. It pairs well with SFP+ media converters such as the MCM10G6SSFP.
✓ Buy it if you commission or troubleshoot single-mode LC transceivers, switch ports or patch panels.
✕ Skip it if your links are multimode or use APC-polished connectors.
