Pluggable Coaxial SFP
The HDX line of routers can also utilize coaxial SFP’s to send signals directly through the
routers without the use of extenders. The Thinklogical CSA-000001 is an electrical SFP
Transceiver module with reclockers designed to transmit and receive SDI signals up to
2.97Gbps over 75
Ω coaxial cables via DIN 1.0/2.3 connectors.

Fiber Optic Cable
Fiber Optic Cable Requirements
Thinklogical recommends SX+ Laser Enhanced (50µm) fiber for your HDX Router and SDI
Xtreme 3G+ Extension System. Multi-mode fiber has the ability to extend up to a maximum of
1000m, where Single-mode fiber has the ability to extend distances beyond 1000m.
Warning! Do not use APC (Angle Physical Contact) Connectors! If inserted
into an SFP+, APCs will destroy the SFP+.
Patch Panels
A Patch Panel is a panel of connectors/ports that connect incoming and outgoing lines. Patch
panels are typically chosen for cable management, allowing long fiber runs to be kept in place
and to minimize handling. If your application involves the use of Single-Mode Extenders,
your patch panel connectors must be APC.
Handling Fiber Optic Cable
Unlike copper cabling, fiber optic cable requires special handling. A small spec of
dust or a scratch to the ferrule tip can attenuate the optical signal so that it becomes
unusable.
Warning! The ends of the connectors (the ferrule) should never come in
contact with any foreign object, including fingertips.
