What is a SFP?

The Small Form-Factor Pluggable (SFP) devices are adapters that generate an interface to allow access to an Ethernet signal through Optical Fiber. These devices can be connected to the inputs of different Ethernet and GPON equipment, allowing the transmission/reception of the information by connecting to sigle-mode or multi-mode fiber or Ethernet cables.
Among the advantages of using SFP modules, we can highlight the reduction of space, lower energy consumption, or the increase of transmission distances.

Which SFP do I need?

Based on the devices to which they are connected, the transmission speed, or the type of cable used, several options are available in the whole range of media converters. The compatibility between the SPFs and the different Ethernet and GPON equipment is described below.

The GPON standard (providing services to the users) is defined by its class (A, B, C, B+, and C+). They differ in the transmitting power and the receiving sensitivity. Most common classes B+ (OLT/ONT) powers lie in the 1.5 dBm - 5 dBm / 0.5 dBm - 5 dBm ranges respectively. Receiving sensitivities <28 dBm / <27dBm respectively. Most common classes C+ (OLT/ONT)powers lie in the 3 dBm - 7 dBm / 0.5 dBm - 5 dBm ranges respectively. Receiving sensitivities <32 dBm / <30 dBm respectively.

The Ethernet standard (data sharing) was developed in order to share information among multiple devices with large capacity. This type of network does not have fixed transmission speeds and wavelengths like GPON networks. One of the most popular standards for Gigabit Ethernet (1000 Mbits) over optical fibre is 1000BASE-LX (1260 nm... 1360 nm,up to 10 km, single mode). For 10 Gigabit Ethernet the most popular standard is 10GBASE-LR (1310 nm, up to 10 km, single mode). In addition, most popular standards for twisted pair (up 100 m) are 1000BASE-T (CAT5, CAT5e or CAT6), and 1000BASE-TX (CAT6 or CAT7).

There was a need to create a device capable of sending/receiving and managing information from a single equipment called transceiver. The most widely used format is SFP (Small Form-factor Pluggable).

Currently, Televes provides two SFP for Gigabit Ethernet (fibre and twisted pair), one SFP+ for 10Gigabit Ethernet (fibre), and two SFP for GPON:
