SFP
Small Form-factor Pluggable - Replaceable Optical Module for Network Connected
Device
SFP28
,An optical transceiver module with a transmission rate of 25Gbps, which complies with
multiple standards and specifications such as IEEE802. 3, SFF-8472, SFF-8402, SFF-
8432 and SFF-8431. Mainly used for 25G Ethernet and 100G (4x25Gbps) Ethernet, and
supports 25G Ethernet and 28.05Gbps (for 32GFC) data rate
SFP20
SX-SFP20 SFP+ optical transceivers are based on 10G Ethernet ( 10Gb/s SFP+ LR
(Long Range) over SMF or MMF ) IEEE 802.3ae standard and SFF-8431 standard.
SFF
Small Form Factor: A class of type of optical connector (Includes LC-Style connector).
SFF-8431, SFF-8419, SFF-8474
SFP+
Small Form Factor Pluggable Plus.
A type of SFP that can send and receive data at rates of up to 10 Gbps.
LASER (L.A.S.E.R.)
Light Amplification by Stimulated Emission of Radiation
Single mode / SMF / OS2 mechanical connector mating / mated-connector loss at
[ 1310nm, 1550nm ] is [ _______ ] dB
0.75 dB
ANSI/TIA-568 stipulates that the maximum INSERTION LOSS for a mated pair
(patch-panel) is [ ___________ ] dB
0.75 dB
Insertion loss (IL)
, The amount of light that is lost between two fixed points in a fiber optic cable. It's
measured in decibels (dB).
Single mode connector mating at 1550nm features an insertion loss of [ _______ ]
dB
0.75 dB
Single mode fusion splice at 1310nm max acceptable loss?
0.30 dB
Single mode fusion splice at 1550nm max acceptable loss?
0.30 dB
Single mode fusion splice max acceptable loss?
0.10 dB

[ Index Matching ] Gel
VCSEL
Vertical Cavity Surface Emitting LASER. A light source for MultiMode Fiber. Used in
combination with LOMMF Fiber.
The advantage over traditional LED (normally limited to 200mb/s) is more concentrated
power allowing for higher data rates (1gb, 10gb, 25gb) in MMF. VCSEL emit infrared
light perpendicular to the mounting surface as opposed to parallel like edge emitting
laser diodes.
LOMMF
Laser-Optimized MultiMode Fiber. Fiber optimized for use with a VCSEL.
