You need dependable connections. This SC connector offers just that. It uses a 2.5 mm ferrule. The design features a push-pull mechanism for simple use. It is perfect for single-mode fiber. This connector ensures low 0.2 dB insertion loss. You get return loss greater than 50 dB.
The connector operates from -40°C to 75°C. It utilizes zirconia ceramic material. Its housing is compact at 9 mm x 56.6 mm. The boot size is 3.0 mm. You will appreciate its durability, rated at 500 cycles. It features a secure latching system and guarantees secure connections.
Expect precise 125 µm fiber alignment. The outer shell is PBT plastic. The product weighs 5 grams. It operates with cable diameters of 3.0 mm, 2.0 mm and 0.9 mm. This is the perfect link for your optical network.
This SC connector highlights top-tier zirconia ceramic. However, this material provides excellent hardness, 9 in Mohs scale. It provides precise 125.5 µm fiber alignment. You will find minimal thermal expansion, 7 x 10^-6 /K coefficient. The ferrule length measures 15.5 mm. Expect superior durability and signal integrity.
Our SC connector uses tight concentricity tolerances, improving alignment. Core-to-cladding concentricity is under 1 µm. The ferrule bore tolerance measures 126 +1/-0 µm. You gain reduced signal loss. Cladding diameter variations are under 125 ± 0.5 µm. The ferrule outside diameter is 2.499 ± 0.0005 mm.
SC connector end-face geometry optimizes light transmission. You achieve a radius of curvature between 10 mm, 25 mm. Apex offset is under 50 µm. Fiber undercut measures at 50 nm maximum. Ferrule end-face angle stands at 0 degrees, plus/minus 0.2 degrees for UPC type.
Choose between UPC, APC for specific network needs. UPC connectors feature a 0-degree polish. APC connectors use an 8-degree angled polish, reducing reflections. APC back reflection is -60 dB. UPC back reflection reaches -50 dB. Either way, you get a reliable connection choice.
SC connector polishing employs a multi-stage process. It utilizes diamond films from 9 µm to 0.5 µm. You will appreciate the final polishing with colloidal silica. At each stage, the surface is getting more refined. The surface roughness is less than 20 nm. The result is minimal signal loss.

Initially, the typical fiber optic cable attenuation is 3dB per 1000 feet at 1310 nanometers. For multi-mode fibers, expect 1.5 dB loss at 850nm. As such, each SC connector reduces signal strength little, preserving link integrity. Ferrules are made of zirconia.
Reflection within the 2.5mm ferrule assembly causes signal degradation in fiber channels. Secondly, you should know, SC APC connectors feature an 8-degree angle polish. Thus, return loss measures below -60 decibels, reducing back reflections. 125-micron fiber core alignment is good.
You should use the TIA/EIA-568 standard for optical loss. Each connection point with these parts has a maximum loss of 0.75 decibels. Therefore, high quality SC connectors minimize the loss per termination. A 900-micron tight-buffered fiber should be inside.
A single-mode fiber link might have a power budget of 25 decibels. Further, ensure receiver sensitivity is -30 dBm. Finally, each SC connector fits within this range, offering sufficient power. Your optical transceiver outputs -5 dBm.
