Routine knowledge of OEMfibers Optical Transceiver

 The composition of the Optical Transceiver: There are launching excitation (TOSA), getting (ROSSA) circuit board IC external accessories

The Optical Transceiver interface is divided into FC type, SC type, LC type, ST type and FTRJ type. RJ45

Optical Transceiver classification

According to the rate: 100Base (100M), 1000Base (Gigabit) for Ethernet applications, 155M, 622M, 2.5G, 10G for 10GE SDH applications

Based on the package: 1×9, SFF, SFP, GBIC SFP+ XFP X2 XENPAK

1×9 package-welding type optical module, general speed is 52M/155M/622M/1.25G, and SC interface is mostly used

SFF package-welding small package optical module, the overall rate is 155M/622M/1.25G/2.25G/4.25G, mostly using LC interface

GBIC package-hot-swappable Gigabit interface optical module, using SC interface

SFP package-hot-swappable small package modules, the existing highest data rate can reach 155M/622M/1.25G/2.125G/4.25G/8G/10G, mostly using LC interface

XENPAK package-used in 10 Gigabit Ethernet, using SC interface

XFP package-10G Optical Transceiver, can be utilized in 10 Gigabit Ethernet, SONET and other systems, mostly using LC interface

According to laser type: LED, VCSEL, FP LD, DFB LD

According to the emission wavelength: 850nm, 1310nm, 1550nm, etc.

Based on the mode useful: non-hot pluggable (1×9, SFF), hot pluggable (GBIC, SFP, XENPAK, XFP)

Fiber optic modules are split into single-mode and multi-mode

The wavelength of light used by single-mode fiber is 1310nm or 1550nm. How big is single-mode fiber is 9-10/125μm, and its transmission distance is normally 10KM 20kM 40KM 70KM 120KM

The light wavelength utilized by multimode fiber is mainly 850 nm or 1310nm. Multimode fiber is 50/125μm or 62.5/125μm, and its own transmission distance differs. Generally, 50/125μm line can transmit 550M, 62.5/ in Gigabit environment. 125μm can only just transmit 330M. (2KM 550M)

Single-mode fiber and multi-mode fiber could be distinguished from color. The outer body of single-mode fiber is usually yellow, and the outer body of multi-mode fiber is orange-red.

The electrical frequency of the optical fiber module: PECL Current: 18 mA, voltage: 3.3V, 5V, temperature: 0~70, -40~70 (industrial grade)

Some commonly used symbols for Optical Transceiver: HP J4858D (850nm 550M) LX SM (1310nm 15KM) LHSM (1310nm 40km) ZX (1550nm 70KM) EZX (1550nm120KM) SR LR ER ZR.Learn:www.oemfibers.com

Differences between cisco GLC-T and cisco GLC-TE

 Cisco GLC-T, GLC-TE and SFP-GE-T optical modules are all Gigabit port optical modules with RJ45 interface and 100m transmission distance. They are cost-saving solutions for Gigabit Ethernet connection in data center, access network and storage area network applications. Therefore, these three types of optical modules are often difficult to distinguish. In fact, the transmission effect of these three optical modules is the same, which optical module can achieve Gigabit transmission, but it is certainly noteworthy that the original Cisco GLC-T and SPF-GE-T optical modules were terminated on June 1, 2017 and replaced by GLC-TE optical module. SFP-GE-T optical module with NEBS 3 ESD function needs to be selected if it is traded directly with the telecommunications company (which requires NEBS).The price of GLC-T and GLC-TE optical modules is low, and they can also meet the needs of Gigabit Ethernet. The Cisco Gigabit optical modules provided by Easy Communications can meet a large number

Why the sfp transceiver not work

 The failure of the sfp optical module is divided into the failure of the transmitter and the failure of the receiver. Through the analysis of the main causes of the phenomenon, the most likely problems are mainly concentrated in the following aspects: The optical port of the  1000base SFP transceiver  is contaminated and damaged Because of the pollution and damage of the optical interface of the module, the loss of the optical link is increased, so that the optical fiber link is unreachable. The main reasons for this phenomenon are the following four points: 1. The optical port of the SFP optical module has been exposed to the environment for a long time, resulting in contamination and contamination of the SFP optical port; 2. The end face of the fiber jumper connected to the  Cisco SFP-10g-sr  optical module has been contaminated, and the SFP optical port provides been contaminated; 3. Improper operation of the end face of the optical connector with pigtails, scratching of the finish
