The Power of the Green LC Connector
The “LC” connector revolutionized networking by halving the space required compared to older SC connectors. When you add the APC (Contato Físico Angular) polish—identifiable by its green housing—you get a connection that virtually eliminates back-reflection, which is vital for the stability of high-power laser sources.

Why the LC/APC-LC/APC-SM-SX is Essential
-
Double the Density: The LC connector’s 1.25mm ceramic ferrule allows network engineers to fit twice as many connections into a 1U patch panel compared to SC or FC connectors.
-
Superior Return Loss: With a return loss often exceeding 65dB, LC/APC cables are mandatory for sensitive applications like GPON, video transmission (CATV), and long-haul DWDM systems.
-
User-Friendly Latch: The RJ45-style “push-pull” latching mechanism provides an audible click, ensuring the connector is fully seated and secure.
-
100% Geometry Testing: Each cable is factory-inspected for core-to-cladding concentricity, ensuring the tiny 9μm cores align with microscopic precision.
Expert Q&A: Professional Insights
Q1: Can I use an LC/APC cable with a standard LC/UPC (Blue) transceiver?
A: No. This is the most common cause of network failure. The APC’s 8-degree angle will not sit flush against a flat UPC face, resulting in a -15dB to -20dB loss and potential hardware damage. Always match Green to Green.
Q2: What is the benefit of Simplex (SX) over Duplex (DX) for LC?
A: Simplex cables are ideal for BiDi (Bi-directional) transceivers, which send and receive data over a single fiber strand using different wavelengths. This saves space and reduces the amount of cabling required by 50%.
Q3: How does the “LSZH” jacket handle tight bends in a rack?
A: Our LSZH jackets are designed for flexibility. However, for extremely tight corners, we recommend our G.657.A1 “Bend Insensitive” version of this LC/APC jumper, which maintains signal integrity even with a 10mm bend radius.
Q4: Is this cable compatible with 400G networks?
A: Yes. While 400G often uses MPO/MTP connectors, the LC/APC-LC/APC single-mode jumper is frequently used in breakout configurations or for connecting 400G-FR4 transceivers that use standard LC duplex/simplex ports.
