12 Core Waterproof SM Pigtail, 10.458 m, SC/APC-NC Wavelocker The coupler is a 1x2

The coupler is a 1x2 1310 nm 50/50 PM Fused Coupler

The LD-635-80-PM-CM is a 635 nm pigtailed laser module

and greatly simplifies the power supply circuit and weak signal detection circuit of APD

This Long Reach (LR) version uses InGaAs avalanche photodiodes (APDs) to achieve high sensitivity

12 Core Waterproof SM Pigtail, 10.458 m, SC/APC-NC Wavelocker The coupler is a 1x2The waterproof pigtail is an optical cable with an optical fiber connector and a durable waterproof connector. It is used to connect the backbone optical cable line and the optical receiver in the optical fiber communication system. They are ultra reliable components featuring low insertion loss and return loss. They come with your choice of simplex or duplex cable configuration and are made to conform to IEC, Telcordia GR 326 CORE standard.
