Yes, you can use it over short fiber runs. The transmitter power output ranges between -15 dBm and -8 dBm, while the receiver overload threshold is -8 dBm. Since the maximum output power does not exceed the receiver overload limit, short-range connections will not saturate or damage the PIN photodiode receiver, and an optical attenuator is generally not required for short testing or patch links.

The LS-SM3106-20C is a commercial-grade optical module with an operating case temperature range of 0°C to 70°C (32°F to 158°F), ideal for indoor data centers, enterprise wiring closets, and climate-controlled switch rooms. If your deployment involves harsh outdoor cabinets or unconditioned environments, we recommend choosing the industrial-grade variant (LS-SM3106-20I), which operates from -40°C to 85°C (-40°F to 185°F).

Deployed these for municipal security camera backhaul over single-mode fiber lines. The 20km transmission reach gives us plenty of optical power budget reserve. No packet drops observed during 72-hour stress testing :-)

One of the dust caps was missing inside the protective tray, so I had to clean the LC ferrule before insertion. Once cleaned, the duplex LC connector snapped in tightly and optical power levels were spot on over a 8km single-mode run.

Installed this 622Mbps SFP module into our Cisco Catalyst switch for a campus fiber link across two office buildings about 4km apart. Link registered immediately with zero CRC errors. DDM readings in CLI show solid optical power levels: TX at -11dBm and RX at -18dBm. Very pleased with the stability =D

Shipping took 5 days via DHL instead of the estimated 3, which slightly delayed our maintenance window. However, the optical transceiver module itself is top-tier. Tested the 1310nm FP laser transmitter over a 15km single-mode fiber span and optical power levels are well within spec.

We used these 20km SMF SFP modules to link outdoor cabinets across our industrial facility. Even in non-climate-controlled enclosures operating near 60°C, the temperature telemetry via DDM remains well within operating thresholds (0 to 70°C). Rock solid reliability =)

The outer cardboard box was slightly crushed during transit, but the individual anti-static ESD packaging protected the transceivers completely. Tested all 10 units on our fiber patch panel at 1310nm wavelength; receiver sensitivity is around -28dBm as advertised. Good quality overall.
