How to avoid mistakes in Fiber Optical transceivers Installation?

When install a Optical fiber optic network, people may make some common mistakes, which were usually overlooked. HTFuture list the most common ones. Hope to give you some guidance for your optical network installation.

1. SFP BIDI transceiver must be used in pair
The SFP BiDi transceiver must be matched correctly. Take an example: The paired BIDI transceivers connect with switch A and switch B. If the switch A connect with TX1310/RX1550nm module, the switch B must be a TX1550/RX1310nm module. The TX1550/RX1310nm module is more expensive than the TX1310nm/RX1550nm one due to the cost of their more powerful lasers. So some network engineers may hope to save money by installing two TX1310nm/RX1550nm. But it doesn’t work. 

2. Understand All kinds of Fiber connectors First
Optical transceivers use a variety of connectors, so make clear their differences before you begin ordering products for a fiber installation is necessary. SC (stick and click) is a square connector. ST (stick and twist) is a round, bayonet-type. LC connectors look like a compact version of the SC connector. It's half the size of SC. SFP transceivers usually use LC connector.  Less common connectors include FC, MT-RJ and E2000.

3. Don’t Use APC connector with UPC Connector
Fiber connections may use Angle Polished Connectors (APC) or Ultra Polished Connectors (UPC), and they are not interchangeable. There are physical differences in the ferules at the end of the terminated fiber within the cable (shown in the figure below). An APC ferrule end-face is polished at an 8° angle, while the UPC is polished at a 0° angle. If the angles are different, some of the light will fail to propagate.

4. Don’t Connect SFP to SFP+ Transceivers
Standard SFP typically support speeds of 100Mbps or 1Gbps. XFP and SFP+  support 10Gbps connections. SFP+  is smaller than XFP and allows for greater port density. Though the size of SFP and SFP+  is the same, you can’t connect SFP+  to a device (SFP) that only supports 1 Gbps.
