GPON vs. EPON Costs Comparison

GPON and EPON Technology Comparison The key factor for determine FTTH network cost is understand the performance characteristics of the PON tecnology. because The PON upstream/downstream bandwidth, bandwidth efficiency and the splitting ratio will affect it. the following table have a brief comparison about the GPON and EPON technology. detailed comparison please read our blog: […]

How to clean SFP (SFFP), XFP, CFP, MSA Transceivers

Most SFP (small form-factor pluggable) module transmitters have an LC (Simplex or duplex) or SC connector with a stub. It is relatively easy to clean following the standard connector if you follow the following cleaning steps: However, the SFP receiver can have an air gap chamber or an internal lens, which makes cleaning and inspecting […]

Connector Cleaning Method

Cleaning Procedure Figure 9 below, illustrates the step-by-step inspection/cleaning procedure that should be rigorously followed before a fiber is connected to another optical component—using this simple procedure can avoid costly network downtime A reliable network begins with connector care and cleaning. Through the years, many devices and procedures have been used. In the past, the way […]

Connector Inspection

Light Budget is one of the key items for designing fiber optic network. in order to create a product that will meet application requirements. To adequately characterize the budget loss, the following key parameters are generally considered: Transmitter: Output power, temperature and aging Fiber connections: Active connection and splices Fiber Cable: fiber attenuation and temperature effect Receiver: Detector […]

ITU T G 652 Fiber Link Design consideration

A concatenated link usually includes a number of spliced factory lengths of optical fibre cable. The requirements for factory lengths are given in clauses 5 and 6. The transmission parameters for concatenated links must take into account not only the performance of the individual cable lengths but also the statistics of concatenation. The transmission characteristics […]

Standard Specification for ITU G 652 Optical Fiber

Recommendation ITU-T G.652 describes the geometrical, mechanical and transmission attributes of a single-mode optical fibre and cable which has zero-dispersion wavelength around 1310 nm. The ITU-T G.652 fibre was originally optimized for use in the 1310 nm wavelength region, but can also be used in the 1550 nm region. This is the latest revision of […]
